The AML Function Reference ────────────────────────── This Function Reference documents all macro language Statements, Builtin functions, and Library functions. Several editor Extension functions are also documented. For a complete description of the Aurora Macro Language (AML), see the Aurora Macro Language Reference. For information on how to install, configure, and use Aurora, see the Aurora Editor Users Guide. To use the Function Reference within a macro: move the cursor to a function name or statement keyword and press <shift f2>. You can use <shift f2> in any document, including the Language Reference (LANGUAGE.DOX) and the Function Quick Reference (QUICKFUN.DOX). You can also navigate through this document by moving the cursor to the 'see also' keywords and pressing <shift f2>. ────────────────────────────────────────────────────────────────────── Copyright (C) 1995 by nuText Systems. All rights reserved worldwide. No parts of this document may be copied in part or in whole, except as provided in the License in the accompanying documentation. ────────────────────────────────────────────────────────────────────── This document is divided into two sections: 1. Language Statements 2. Functions (builtin functions and library functions) Statements and functions are sorted alphabetically in each section. Statements are indicated by the label [Statement], library functions are indicates by [Lib], and extension functions are indicated by [Ext]. Builtin functions are not labeled. Each library function also displays the object where it is defined (i.e [Lib][edit]). ┌─────────────────────────────────────────────────────────────────────┐ │ Language Statements │ └─────────────────────────────────────────────────────────────────────┘ break [Statement] ────────────────────────────────────────────────────────────────────── remarks: The 'break' statement will force an unconditional exit from 'loop', 'repeat', and 'while' loops. returns: nothing see also: loop, repeat, while example: loop keycode = getkey case keycode when <esc> // <esc> exits the loop break otherwise say "you pressed " + (getkeyname keycode) end end case [Statement] ────────────────────────────────────────────────────────────────────── format: case case_expr when when_expr expressions when when_expr, when_expr, when_expr expressions . . otherwise expressions end The 'otherwise' clause is optional. remarks: The 'case' statement evaluates 'case_expr', and then evaluates each 'when' expression in order, until one is found whose value is equal to the value of 'case_expr'. If a matching 'when' expression is found, the expressions associated with the 'when' statement are evaluated. Multiple 'when' expressions (separated by commas) may be specified within a single 'when' clause. If no matching 'when' expressions are found, then the 'otherwise' clause (if present) is evaluated. returns: The value of the last expression evaluated in the 'when' or 'otherwise' clause. see also: if, if? example: case value when 1 say "value is one" when 3, 7 say "value is three or seven" when "abc" + "d" say "value is abcd" otherwise say "value is " + value end value = case value when 1 "one" when 2 "two" otherwise "undefined" end databuf [Statement] ────────────────────────────────────────────────────────────────────── format: databuf buffer . . end remarks: This statement creates a new buffer and initializes the buffer with data, or adds data to the end of an existing buffer. 'buffer' specifies the bufferid. Each expression listed within the databuf-end group becomes a separate line in the buffer. At least one line is required. This statement is generally used to define an 'inline' data buffer in a macro, without requiring a separate file to be loaded. returns: nothing see also: createbbuf, createbuf, destroybuf example: databuf "abc" // bufferid 'abc' "first line" // 1st line x + 5 - y // 2rd line y // 3th line "a string" // 4th line end define [Statement] ────────────────────────────────────────────────────────────────────── format: define . . end remarks: This statement defines a section of macro code which is executed at compile-time. No object code is generated for any expressions contained within the define-end group. Any functions defined within the define-end group are evaluated at compile time when called. Similarly, object variables which are assigned values within the define-end group are treated as constants when referenced outside the define-end group. returns: nothing see also: forward, function, include, set, var forward identifier [Statement] ────────────────────────────────────────────────────────────────────── remarks: This keyword defines the specified identifier as a function name. If a function is called before it is defined with the 'function' statement, the 'forward' keyword must be used to inform the compiler that the identifier is a function name. returns: nothing see also: function, key, var function [Statement] ────────────────────────────────────────────────────────────────────── format: function functionname (arg1 arg2 ...) . . end remarks: This statement defines a function in the current object with the name 'functionname'. Expressions contained within the function definition will be evaluated when the function is called. Function arguments can be referenced as variables within the function by listing them within parentheses after the function name. Note that arguments can also be referenced with the 'arg' function (see the 'arg' function). returns: nothing see also: arg, forward, key example: function hello (name) say "Hello " + name + '!' end if [Statement] ────────────────────────────────────────────────────────────────────── format: if if_expr then expressions elseif elseif_expr then expressions . . else expressions end The 'elseif' and 'else' clauses are optional. The keyword 'then' is also optional, but may make the statement easier to read. remarks: The 'if' statement evaluates the expression 'if_expr'. If the value is TRUE (not zero and not null), then the expressions in the 'if' clause are evaluated. If the value is not TRUE, then the expression 'elseif_expr' is evaluated. If the value is TRUE, then the expressions in the 'elseif' clause are evaluated, otherwise the expressions in the 'else' clause (if present) are evaluated. Multiple 'elseif' clauses may be specified. returns: The value of the last expression evaluated in the 'if', 'elseif', or 'else' clauses. see also: case, if? if? if_expr then_expr else_expr [Statement] ────────────────────────────────────────────────────────────────────── remarks: The 'if?' statement is a shorter form of the 'if' statement (see the 'if' statement'). The keywords 'then', 'elseif', and 'else' are not used. The expression 'else_expr' is optional. The 'if?' statement is primarily intended for use within expressions, where it may be more convenient than the 'if' statement. returns: The value of 'then_expr' or 'else_expr'. see also: case, if example: string1 = if? a == 1 "a is one" "a is not one" key [Statement] ────────────────────────────────────────────────────────────────────── format: key <key or event> (arg1 arg2 ...) . . end The 'end' keyword is not required if this statement is followed by another 'key' or 'function' statement. remarks: This statement defines an keyboard event handling function in the current object with for the event name: <key or event>. Expressions contained within the function definition will be evaluated whenever the event is is sent to the current object. Function arguments can be referenced as variables within the function by listing them within parentheses after the function name. Note that arguments can also be referenced with the 'arg' function (see the 'arg' function). For all keyboard events generated by the editor except <char>, a keycode is passed as the first argument. The <char> event handling function is passed the ASCII character entered as the first argument, and the keycode as the second argument. returns: nothing see also: arg, forward, function example: key <ctrl c> (keycode) say "you pressed <ctrl c>, keycode=" + keycode end keyword keyword1, keyword2, ... [Statement] ────────────────────────────────────────────────────────────────────── remarks: This statement inserts 'keyword1', 'keyword2', etc. as syntax highlighting keywords in the current (executing) object. The keywords must be separated by commas. Syntax highlighting keywords are stored as object variables whose value is the keyword color. If the value is null, then the keyword color defined in the 'syntax' function is assumed. The 'keyword' statement always assigns a value of null to the object variable. returns: nothing see also: setsyntax, syntax example: see the configuration file SYNTAX.AML include expression [Statement] ────────────────────────────────────────────────────────────────────── remarks: This statement includes the macro language file defined by 'expression' at the current source code location. The specified expression is always evaluated at compile time. Any user-defined variables or functions referenced within the expression must have been previously defined within a 'define-end' group. This statement will include both macro source (.AML) files and compiled macro (.X) files. returns: nothing see also: define example: include "d:\\macros.aml" include drive + path + filename loop [Statement] ────────────────────────────────────────────────────────────────────── format: loop expressions end remarks: The 'loop' statement evaluates 'expressions' repeatedly until a 'break' or 'return' statement is encountered. returns: nothing see also: break, repeat, return, while menu [Statement] ────────────────────────────────────────────────────────────────────── format: menu menuname item description1 expressions1 item description2 expressions2 . . end remarks: This statement creates a new menu buffer with the bufferid 'menuname'. 'description1', 'description2', etc. are the text strings associated with each item on the menu. Each description may contain one ampersand character (&) indicating that the character following it is to be highlighted. 'expressions1', 'expressions2', etc. are macro expressions to be associated with the menu items. These expressions can be retrieved and evaluated when a menu item is selected (see the 'getmenu' function). returns: The new menu bufferid if successful, otherwise null. see also: asciibuf, createbbuf, destroybuf, loadbuf, menubar, popup example: menu "Colors" item "&Red" say "you selected red" item "&Green" say "you selected green" item "&Blue" say "you selected blue" end menubar [Statement] ────────────────────────────────────────────────────────────────────── format: menubar window bar[1-5] item description1 expressions1 item description2 expressions2 . . end remarks: This statement creates or changes a menu bar for a window. If 'window' is null, then the current window is assumed. 'description1', 'description2', etc. are the text strings associated with each item on the menu bar. Each description may contain one ampersand character (&) indicating that the character following it is to be highlighted. If a pair of ampersand characters (&&) is specified, the character is highlighted with the window title bar control color. 'expressions1', 'expressions2', etc. are macro expressions to be associated with the menu bar items. These expressions can be retrieved and evaluated when a menu bar item is selected (see the 'getmenubar' function). Up to five menu bars can be defined for one window. 'bar' specifies which of the five menu bars is being defined, and can be one of the following values: 1 - the primary menu bar at the top of the window, under the north title bar (if any) 2 - menu bar 2 directly underneath the primary menu bar 3 - menu bar 3 directly underneath menu bar 2 4 - menu bar 4 at the bottom of the window, above the south title bar (if any) 5 - vertical menu bar 5 at the left edge of the client area If 'bar' is null, then 1 is assumed. returns: TRUE if successful, otherwise null. see also: getmenubar, menu example: menubar '' 1 // primary menu bar item "&Red" say "you selected red" item "&Green" say "you selected green" item "&Blue" say "you selected blue" end object [Statement] ────────────────────────────────────────────────────────────────────── format: object objectname ( parent1 parent2 ... ) The inheritance list (parent1 parent2 ...) is optional. remarks: This statement changes the current (executing) object to 'objectname'. If the object does not exist, then it is created. If the inheritance path '(parent1 parent2 ...)' is specified, then the object will inherit functions and object variables from the objects 'parent1', 'parent2', etc. returns: nothing see also: destroyobject, getcurrobj, inheritkeys, object? example: object abc // makes 'abc' the current object (and creates it // if it doesn't exist) object abc (def xyz) // makes 'abc' the current object (and creates it // if it doesn't exist). 'abc' will inherit // code and data from objects 'def' and 'xyz' ref variable [Statement] ────────────────────────────────────────────────────────────────────── remarks: The 'ref' keyword can be used to return more than one value from a function. When 'ref' is specified immediately before a local or global variable in a function call, it indicates that the variable is to be passed 'by reference' to the function. If the variable is modified in the called function, it is also modified where it was called. returns: nothing example: function modify (c d) c = 13 d = 14 end function callmod a = 1 b = 2 modify ref a ref b return a + b // returns 27 end repeat [Statement] ────────────────────────────────────────────────────────────────────── format: repeat expressions until until_expr remarks: The 'repeat' statement evaluates 'expressions' repeatedly until the value of the expression 'until_expr' is TRUE (not zero and not null). 'until_expr' is tested after the first iteration of the loop. The 'break' or 'return' statements can be used to force an exit from the loop. returns: null see also: break, loop, return, while example: var i repeat // counts from 0 to 9 say "i is " + i delay 500 i = i + 1 until i == 10 return expression [Statement] ────────────────────────────────────────────────────────────────────── remarks: This statement returns the value of 'expression' immediately and unconditionally to the calling function. returns: the value of the specified expression. example: return "The value is: 13" // returns a string return 6 + 7 // returns 13 return // returns the null string set variable expression [Statement] ────────────────────────────────────────────────────────────────────── remarks: Assigns the value of 'expression' to an object variable in the current (executing) object. Leading underscores are ignored. returns: nothing see also: function?, lookup, setobj, setx, setxfun, setxobj, unsetx example: set Two 2 set _Two 2 // underscore is ignored set number 1 + 2 + x - 4 set abc_string 'a' + b + 'c' set "A variable" 2 setobj variable expression objexpression [Statement] ────────────────────────────────────────────────────────────────────── remarks: Assigns the value of 'expression' to an object variable in the object defined by 'objexpression'. An object must be specified returns: nothing see also: function?, lookup, set, setx, setxfun, setxobj, unsetx example: setobj Two 2 "edit" setobj Two 2 "ed" + "it" setx varexpression expression [Statement] ────────────────────────────────────────────────────────────────────── remarks: Assigns the value of 'expression' to an object variable defined by 'varexpression' in the current object. returns: nothing see also: function?, lookup, set, setobj, setxfun, setxobj, unsetx example: setx "FourTeen" 14 setx "Four" + "Teen" 8 + 6 // assigns 14 to the object // variable "FourTeen" variable = "Fourteen" // assigns 14 to the object setx variable 14 // variable "FourTeen" setxfun funexpression expression objexpression [Statement] ────────────────────────────────────────────────────────────────────── remarks: Changes the function definition of the function 'funexpression' in the object 'objexpression' to the macro source code in the string 'expression'. An object must be specified. This statement can be used to change the definition of a function to macro source code which is not known at compile-time. returns: nothing see also: function?, lookup, set, setobj, setx, setxobj, unsetx example: setxfun "<ctrl d>" "beep 400 400" "edit" // assigns the macro code 'beep 400 400' to <ctrl d> // in the object 'edit' setxobj varexpression expression objexpression [Statement] ────────────────────────────────────────────────────────────────────── remarks: Assigns the value of 'expression' to an object variable defined by 'varexpression' in the object defined by 'objexpression'. An object must be specified. returns: nothing see also: function?, lookup, set, setobj, setx, setxfun, unsetx example: setxobj "Four" + "Teen" 8 + 6 "edit" // assigns 14 to the object variable 'Fourteen' in // the object 'edit' var identifier [Statement] ────────────────────────────────────────────────────────────────────── remarks: This keyword defines the specified identifier as a variable name, and initializes it to zero when entering a macro or function. If a variable is referenced before it is assigned a value (and not referenced in a function argument list), then this keyword must be used to inform the compiler that the specified identifier is a variable name. returns: nothing see also: forward example: function count (b) var a while a < b do a = a + 1 end end while [Statement] ────────────────────────────────────────────────────────────────────── format: while while_expr do expressions end The keyword 'do' is optional, but may make the statement easier to read. remarks: The 'while' statement evaluates 'expressions' repeatedly while the expression 'while_expr' is TRUE (not zero and not null). 'while_expr' is tested before the first iteration of the loop. The 'break' or 'return' statements can be used to force an exit from the loop. returns: null see also: break, loop, repeat, return ┌─────────────────────────────────────────────────────────────────────┐ │ Functions │ └─────────────────────────────────────────────────────────────────────┘ about [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays an about box with the editor version, and the date and time. returns: The button pressed (Ok), or null if nothing was pressed. see also: askprint, finddlg, repldlg, scandlg addhistory historybuffer string [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Adds 'string' to the specified history buffer and makes it the most recently used history string. The history buffer is created if it does not exist. returns: nothing see also: askhistory, gethiststr, pophistory example: addhistory "_load" "C:\\FILE.TXT" // adds C:\FILE.TXT to the history buffer '_load' addhistory "_find" "apples" // adds 'apples' to the history buffer '_find' addline string col row buffer ────────────────────────────────────────────────────────────────────── remarks: Inserts a new line containing the specified string into a buffer. This function is almost identical to the 'insline' function, except that new lines are added to the end of the buffer if 'row' is not specified (see 'insline'). returns: TRUE if successful, otherwise null. see also: delline, insline, insabove, joinline, splitline example: addline // adds a new blank line to the end of the // current buffer addline "Last line" // adds a new line with the text 'Last line' // after the last line in the current buffer adjustcol col window ────────────────────────────────────────────────────────────────────── remarks: Scrolls a window left or right relative to the position of the cursor in the window. If 'window' is not specified, the current window is assumed. This function does not move the cursor in the buffer. The window is scrolled so that the cursor appears 'col' minus 1 columns from the left edge of the client area. If 'col' is not specified, the window is scrolled to a position that leaves the cursor in the vertical center of the window. returns: nothing see also: adjustrow example: adjustcol // attempts to scroll the window so that the cursor // is vertically centered in the window. adjustcol 3 // attempts to scroll the window so that the cursor // is 3 columns from the left edge of the window adjustrow row window ────────────────────────────────────────────────────────────────────── remarks: Scrolls a window up or down relative to the position of the cursor in the window. If 'window' is not specified, the current window is assumed. This function does not move the cursor in the buffer. The window is scrolled so that the cursor appears 'row' minus 1 lines from the top edge of the client area. If 'row' is not specified, the window is scrolled to a position that leaves the cursor in the horizontal center of the window. returns: nothing see also: adjustcol example: adjustrow // attempts to scroll the window so that the cursor // is horizontally centered in the window. adjustrow 3 // attempts to scroll the window so that the cursor // is 3 rows from the top edge of the window actualrow (+/-)lines row buffer ────────────────────────────────────────────────────────────────────── remarks: This function returns the actual line number which is the apparent distance on the screen of 'lines' lines away from the specified row. If 'buffer' is null or not specified, then the current buffer is assumed. If 'row' is not specified, then the line at the cursor is assumed. returns: A line number if successful, otherwise null. see also: apparentrow, fold?, getfold example: actualrow -5 // returns the line number which appears to be 5 // lines above the current line on the screen apparentrow (+/-)lines row buffer ────────────────────────────────────────────────────────────────────── remarks: This function returns the apparent line number on the screen which is the actual distance of 'lines' lines away from the specified row. If 'buffer' is null or not specified, then the current buffer is assumed. If 'row' is not specified, then the line at the cursor is assumed. returns: A line number if successful, otherwise null. see also: actualrow, fold?, getfold example: apparentrow 5 // returns the apparent line number on the screen // of the line 5 lines below the current line arg n ────────────────────────────────────────────────────────────────────── remarks: Retrieves the 'nth' argument, or the number of arguments passed to the currently executing function. If 'n' is zero or not specified, then the number of arguments is returned, otherwise the 'nth' argument is returned. returns: A function argument or the number of function arguments. see also: function, key example: function abc say (arg) + " args passed, first arg is: " + (arg 1) end abc 1 2 3 // displays: '3 args passed, first is: 1' asciibuf buffer ────────────────────────────────────────────────────────────────────── remarks: This function creates a new buffer containing an ASCII chart with 256 lines - one for each ASCII character. The new buffer will become the current buffer. If 'buffer' is null or not specified, a unique bufferid will be assigned. Note: this function will not display the new buffer in a window. The 'popup' or 'openbuf' library functions should be used to display the buffer. returns: The new bufferid if successful, otherwise null. see also: asciibuf, createbbuf, destroybuf, loadbuf, menu, openbuf, popup ask prompt history init title opt=[c12d] width [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Prompts the user to enter a string. The following parameters may be specified: prompt - the prompt displayed to the user history - the history buffer to use in the prompt init - the initial value to place in the prompt title - the prompt title (dialog boxes only) width - the prompt width (dialog boxes only) The following 'prompt style' options may also be specified: c - command line prompt 1 - one-line box prompt 2 - two-line box prompt d - dialog box prompt If no options are specified, the value of 'PromptStyle' in CONFIG.AML is used as the default prompt style. If a history bufferid is specified and does not already exist, then it is created. Note that entered strings are not automatically added to the history buffer (the 'addhistory' function must be used). returns: This function returns the string entered. If nothing is entered and the <enter> key is pressed, then one blank (ASCII 32) is returned. If the prompt is cancelled, then null is returned. see also: addhistory, askfile, askprint, okbox, popup, repldlg, scandlg, yncbox example: ask "Enter a string" // prompts for a string ask "Enter a file name" "_load" "C:\\FILE.TXT" // prompts for a string, initializing the prompt with // C:\FILE.TXT. The "_load" history buffer is // available within the prompt ask "Enter a string" '' "initial string" "Enter" 'd' 20 // prompts for a string using a dialog box prompt of // width 20 with the title 'Enter". The prompt // is initialized with "initial string". askfile filespec title sortoptions fmgroptions bufname [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays a file selection menu based on 'filespec'. The following parameters can be specified: title - the menu title sortoptions - One of the following sort options can be specified: d - file date/time (descending) e - file extension n - file name o - DOS default order s - file size (descending) If no options are specified, the setting 'FmgrSort' in CONFIG.AML is assumed. fmgroptions - One of the following options can be specified: d - show subdirectories h - show hidden & system files k - show file sizes in 1k increments 1 - show directories first when sorting by name If no options are specified, the setting 'FmgrOpt' in CONFIG.AML is assumed. bufname - A buffer name to be used for the menu. If a buffer name is specified, the menu will 'remember' its window and cursor positions, and associate them with the buffer name. returns: The selected file or directory, or null if nothing was selected. see also: popup example: askfile "C:\\*.*" "Select a file" // displays a file selection menu for the C drive askfile "C:\\*.*" "Select a file" 's' 'dk' // displays a file selection menu for the C drive, // sorted by file size. The menu will show // subdirectories, and file sizes in 1k increments askhistory [Lib][prompt] ────────────────────────────────────────────────────────────────────── remarks: Displays a history popup menu for the current prompt. If a string is selected, it is entered automatically into the prompt. This function is only for use within prompts. returns: The string selected from the popup menu, or null if nothing was selected or the history buffer does not exist. see also: pophistory askprint [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays a print settings dialog box. returns: The button pressed (Ok), or null if nothing was pressed. see also: about, finddlg, repldlg, scandlg assignkey [Lib][mon] ────────────────────────────────────────────────────────────────────── remarks: Assigns the current scrap key macro to a key.

If 'buffer' is null or not specified, the current buffer is assumed. returns: non-zero if the buffer is modified, otherwise null. see also: bufchanged?, bufferflag buffer? buffer ────────────────────────────────────────────────────────────────────── remarks: Tests if a buffer exists. If 'buffer' is null or not specified, the current buffer is assumed. returns: TRUE if the buffer exists, otherwise null. see also: trunc? bufferflag opt=[cdm-] buffer ────────────────────────────────────────────────────────────────────── remarks: Turns buffer flags on or off. If 'buffer' is null or not specified, the current buffer is assumed. The following flags can be specified: d - process 'dirty' or modified lines m - buffer 'modified' flag - - turns off flags If option '-' is specified, any other specified flags will be turned off, otherwise all specified flags will be turned on. The following option can also be specified: c - clear all 'dirty' or modified lines returns: nothing see also: bufchanged?, bufferflag?, lineflag, lineflag? example: bufferflag "-m" // turn off the buffer-modified flag bufferflag "c" // clear all modified lines bufferflag? opt=[dm] buffer ────────────────────────────────────────────────────────────────────── remarks: Tests if buffer flags are on.

The third argument specifies the binary line length. d - includes subdirectories when loading directories h - includes hidden/system files when loading directories k - shows file sizes in 1k increments when loading directories x - disables conversion of fold comments to folds 1 - sorts subdirectories first when loading directories If option 'b' is specified, the file is loaded in binary mode and the third argument specifies a fixed binary line length. If the third argument is not specified, the default binary line length is 64. If option 'b' is not specified, the third argument specifies a 1 or 2 byte line delimiter string to use. If the third argument is not specified, a line delimiter of 0D0Ah (CR/LF) is assumed. The argument 'trunc' specifies the length at which lines are truncated. If 'trunc' is zero or not specified, the editor maximum (16000) is assumed. The argument 'comment' specifies the fold comment string to look for when converting fold comments to text folds during the loading process. Specifying option 'x' disables the conversion. Note: this function will not display the new buffer in a window.

This function returns the fully qualified filename or directory if found, otherwise it returns null. returns: TRUE if successful, otherwise null. see also: createdir, scanfile example: locatefile "FILE.TXT" "C:\\" // returns C:\FILE.TXT, if FILE.TXT is found in C:\ locatefile "FILE.TXT" (getenv "PATH") // returns FILE.TXT (fully qualified), if FILE.TXT is // found in the DOS PATH locatefile "MACROS" "D:\\AURORA" 'd' // returns D:\MACROS\AURORA, if MACROS is a directory // in D:\AURORA lookup varexpression objexpression opt=[e] ────────────────────────────────────────────────────────────────────── remarks: Gets the value of an object variable defined by 'varexpression' in the object defined by 'objexpression'. If 'objexpression' is not specified, the current object is assumed. If option 'e' is specified, then this function only tests for the existence of the object variable. returns: If option 'e' is not specified, this function returns the value of an object variable. If option 'e' is specified, this function returns non-zero if the object variable exists, otherwise it returns null. see also: function?, set, setobj, setx, setxfun, setxobj, unsetx example: lookup "VidCols" lookup "Vid" + "Cols" "prf" lookup variable // returns the value of an object variable whose // name is the value of 'variable' mark? mark ────────────────────────────────────────────────────────────────────── remarks: Tests if a mark exists.

A character mark designates a stream of one or more characters in a buffer. If 'buffer' is null or not specified, the current buffer is assumed. If 'mark' is not specified, the default markid is assumed. If the mark does not exist then a new mark is created. If the mark already exists and is not located in the specified buffer, then it is moved there. The mark will be sized to span from 'startcol','toprow' to 'endcol','botrow'. If none of these are specified, then the cursor line and column are assumed and the mark is left 'open' (moving the cursor resizes the mark).

The following printer settings can be specified: printer - reserved for future use pagesize - specifies the lines per page of printed output. This includes the top margin and the bottom margin. After the specified lines per page have been printed, a formfeed character (ASCII 12) will be sent to the printer and a new page will be started. If 'pagesize' is zero, printing will be continuous (no formfeed characters will be sent to the printer) and 'topmarg', 'bottommarg', and the option 'p' will be ignored. linespace - specifies the number of lines to advance after printing each line of output. A value of 1 generates single-spaced output, 2 generates double-spaced output, and so on. copies - specifies the number of copies to print. topmarg - specifies the number of blank lines to precede printed output at the top of each page. This value is included in 'pagesize'. 'topmarg' is ignored if 'pagesize' is zero. bottommarg - specifies the number of blank lines to follow printed output at the bottom of each page. This value is included in 'pagesize'. 'bottommarg' is ignored if 'pagesize' is zero. leftmarg - specifies the number of blank columns to precede the printed output on each line. rightmarg - specifies the column position at which to truncate each printed line. This column position is relative to column zero of the printed output, not the file being printed. If zero is specified, lines are not truncated. Any of the following print options can also be specified: h - prints a header at the top of each page. The header is specified in the 'printbuf' or 'printblock' functions when printing. This option is ignored if 'pagesize' is zero. f - prints a footer at the bottom of each page. The footer is specified in the 'printbuf' or 'printblock' functions when printing. This option is ignored if 'pagesize' is zero. s - adds a separator line after the header line and before the footer line. p - prints a right justified page number on the header and footer lines. If neither a header or footer was specified, a blank header line is assumed. This option is ignored if 'pagesize' is zero. l - prints a line number at the beginning of each line. e - sends a formfeed character to the printer when printing is completed. returns: nothing see also: printblock, printbuf process ────────────────────────────────────────────────────────────────────── remarks: Creates an editor subprocess by invoking the editor recursively.

If 'buffer' is not specified, the current buffer is assumed. See the 'find' function for a list of available search options. If option 'a' is specified, all occurrences of the 'searchstr' found will be replaced with 'replacestr'. If option 'a' is not specified, then only the first occurrence of the search string is replaced. If the string is found and neither of the search options 'a' or 'n' are specified, then the cursor is moved to the beginning of the found string, otherwise the cursor does not move. returns: If option 'a' is specified, the number of replacements made is returned, otherwise the length of the replaced string is returned. If nothing is found, then null is returned. see also: find, search example: replace "apples" "oranges" // replaces the next occurrence of 'apples' with // 'oranges' in the current buffer, starting at one // character after the cursor position replace "apples" "oranges" "ag" // replaces all occurrences of 'apples' with 'oranges' // in the current buffer and returns the number of // occurrences.

'milliseconds' specifies the time interval in milliseconds. The first function call will occur after the specified time interval has expired (not after the 'setrepeat' call). The function is called in the specified object, passing the optional arguments 'arg1', 'arg2', etc. If 'object' is not specified, the current event object is assumed. 'timerid' uniquely identifies the timer. If a timerid is not specified, a unique timerid is generated. A maximum of 16 timerid's may be active at one time. returns: The timerid if successful, otherwise null. see also: destroytimer, setalarm, settimer, timer? example: setrepeat "xyz" 1000 '' "abc" // sets timerid 'xyz' to call the function 'abc' every // second in the current event object setrepeat "t1" 0 '' "idle" // sets timerid 't1' to call the function 'idle' // repeatedly in the current event object whenever // the editor is idle setshadow right bottom window ────────────────────────────────────────────────────────────────────── remarks: Adds or removes window shadows. If 'window' is not specified, the current window is assumed. 'bottom' and 'right' specify the shadow thickness on the bottom and right borders.

See the 'setting' command for a description of window settings. returns: Non-zero if one of the specified settings is ON, otherwise null. see also: getsettings, setting example: setting? "lw" // tests if word wrap or live word wrap are ON settitle string opt=[nsewlcrdxh1z] titleid[1-5] window ────────────────────────────────────────────────────────────────────── remarks: Changes a window title. If 'window' is null or not specified, then the current window is assumed. Each window can have up to 5 titles. 'titleid' (1-5) specifies which window title to change. If the 'titleid' is null or not specified, then 1 (the primary title) is assumed. Any combination of the following options can be specified: e - places the title on east title bar n - places the title on north title bar s - places the title on south title bar w - places the title on west title bar l - left justifies the title c - centers the title r - right justifies the title d - redraws the window title immediately after this function call x - sets the title to the 'default status line'. The status line displays information about the buffer (if any) displayed in the window. h - checks for the highlight character "&". Specifying "&" before a character in the title indicates that the character is to be highlighted. 1 - the title is not padded with spaces. Normally the title is padded with one space if it is left or right justified. z - hides the title. This can be used to associate a string with a window by storing it as a hidden window title. This option must also be used to specify a title for the end-of-text line (see the 'eotstring' function). If no options are specified, and the title has not been previously set, the options 'nl1' are assumed. If the title has been previously set, then the options of the previous title are assumed. returns: TRUE if successful, otherwise null. see also: eotstring, gettitle example: settitle "Hello World" // sets window title 1 to 'Hello World' settitle "Hello World" "cs" 3 // sets window title 3 to 'Hello World' and // centers it on the south title bar setvideo cols rows color fillstring ────────────────────────────────────────────────────────────────────── remarks: Changes the video mode and/or sets the background color attribute and background fill string. Either operation can be done separately or simultaneously. When changing the video mode, 'cols' must be 40 or 80 and 'rows' must be 12, 14, 21, 25, 28, 43, or 50. If 'cols' or 'rows' are zero or null, the video mode is not changed. Specifying either 'color' or 'fillstring' changes the video background. If 'color' is not specified, black (0) is assumed. If 'fillstring' is not specified, blanks are assumed. The maximum size of 'fillstring' is 50 characters. returns: TRUE if successful, otherwise null. see also: videomode, writebak setwinctrl controlstring rightcontrol window ────────────────────────────────────────────────────────────────────── remarks: Changes the one-character title bar controls for a window. If 'window' is not specified, the current window is assumed. Controls are normally placed on the north title bar unless south title bar controls are specified with the 'setframe' function. 'controlstring' is a string of the one-character title bar controls to appear on the title bar from left to right. By default, controls are left justified on the title bar. If specified, 'rightcontrol' defines the character position in 'controlstring' of the first right justified control. returns: TRUE if successful, otherwise null. see also: getwinctrl example: setwinctrl "" // places one left justified control () on the // title bar setwinctrl "≡" 2 // places 3 controls on the title bar. (≡) is // left justified, () and () are right justified setwincurs cursor window ────────────────────────────────────────────────────────────────────── remarks: Attaches a cursor to a window and associates a buffer with a window. If 'window' is not specified, the current window is assumed. When a cursor is attached to a window, the window will display the buffer associated with the cursor. If 'cursor' is null or not specified, then the cursor is detached from the window and the window will no longer display a buffer. Only one cursor may be associated with a window at one time. Windows that do not display a buffer do not need to use this call. returns: TRUE if successful, otherwise null. see also: getwincurs setwinobj object window ────────────────────────────────────────────────────────────────────── remarks: Sets the window event object associated with a window. If 'window' is not specified, the current window is assumed. This function also changes the current event object to 'object'. Whenever a window becomes the current window, the current event object is set to the window event object. This allows an object 'class' to be associated with an individual window. returns: nothing see also: eventobject, getwinobj example: setwinobj "edit" // sets the event object for the current window to // 'edit', and also changes the current event object // to 'edit' shiftblock (+/-)cols mark fillchar ────────────────────────────────────────────────────────────────────── remarks: Shifts marked text to the left or to the right. If 'mark' is not specified, the default markid is assumed. 'cols' specifies the number of columns to shift. Positive values shift text to the right and negative values shift text to the left. 'fillchar' is the character to use when filling empty spaces created by shifting to the right. If 'fillchar' is not specified, blanks (ASCII 32) are assumed. returns: TRUE if successful, otherwise null. see also: delchar, instext example: shiftblock -1 // shifts the text in default markid one space to the // left shiftblock 1 '' '>' // shifts the text in the default markid one space to // the right, filling empty spaces with '>' shiftkey? shiftstate ────────────────────────────────────────────────────────────────────── remarks: Tests if the specified shift key(s) are currently pressed down. 'shiftstate' can be any combination of the following values OR'ed together bitwise: 01h - right shift key down 10h - scroll lock ON 02h - left shift key down 20h - num lock ON 04h - ctrl key down 40h - caps lock ON 08h - alt key down 80h - insert ON If shiftstate is not specified, then a value of 03h (right and left shift keys) is assumed. returns: Non-zero if the specified shift keys are down, otherwise zero. see also: event?, keyhit? example: shiftkey? // tests if the left or right shift keys are pressed shiftkey? 12h // tests if the <ctrl> or <alt> keys are pressed sizekey [Lib][win] ────────────────────────────────────────────────────────────────────── remarks: Resizes the current window using the cursor keys. returns: nothing see also: pankey, sizewin sizewin l t r b reps opt=[acdrswz1] window [Lib][win] ────────────────────────────────────────────────────────────────────── remarks: Resizes the specified window. If 'window' is not specified, the current window is assumed. This function is nearly identical to the 'sizewindow' builtin function, except that the window title bar controls are set properly after resizing, and 'reps' (sizing repetitions) can be specified. returns: nothing see also: movewindow, sizewindow sizewindow l t r b opt=[acdrswz1] window relativewindow ────────────────────────────────────────────────────────────────────── remarks: Changes the size and position of a window. If 'window' is not specified, the current window is assumed. When a window is resized, all parts of the window are redrawn immediately. 'l', 't', 'r', and 'b' specify the new window coordinates. The following options can be specified: a - The coordinates are absolute and are relative to an 'origin'. The location of the origin depends on which of the following options are also specified: d - the origin is located at the top left corner of the physical screen w - the origin is located at the top left corner of the window 'relativewindow' 1 - the origin is located at the top left corner of the client area of the window 'relativewindow' z - the origin is located at the virtual coordinates (0,0) If option 'a' is specified and none of the above options are specified, then 'd' is assumed. r - the coordinates are relative to another rectangle on the screen. 'l', 't', 'r', and 'b' specify relative offsets from the left, top, right, and bottom edges of the rectangle. The location of the rectangle depends on which of the following options are also specified: d - the rectangle is the physical screen w - the rectangle is the main window area of the window 'relativewindow' 1 - the rectangle is the client area of the window 'relativewindow' z - the rectangle is the main window area of the window being resized (relative to itself, in other words) If option 'r' is specified and none of the above options are specified, then 'z' is assumed. c - the coordinates specify the size of the client area of the window being sized, not the entire window. s - scrolls the window to keep the cursor visible, if needed If no options are specified, options 'rz' are assumed. returns: TRUE if successful, otherwise null. see also: getcoord, movewindow example: sizewindow -1 -1 1 1 // expands the current window size by 1 in all four // directions sizewindow 0 0 0 0 "rd" // sizes the current window to fill the entire screen // with all the borders visible sizewindow 6 5 72 20 "ad" // sizes the current window relative to the upper // left corner of the screen sizewindow 6 5 72 20 "a1" '' "abc" // sizes the current window relative to the upper // left corner of the client area of window 'abc' shortbox message title opt=[b] [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays the specified message in a popup window without an 'Ok' button. If a title is not specified, 'Message' is assumed. If option 'b' is specified, the PC speaker beeps. returns: nothing see also: msgbox, okbox, say, yncbox example: shortbox "This is a message with a beep!" 'b' showcursor top bottom ────────────────────────────────────────────────────────────────────── remarks: Shows the physical cursor in the current window. If the current window contains a buffer, the effects of this function are temporary and may disappear the next time the display is updated. If 'top' and 'bottom' are specified, the physical cursor size is changed. 'top' and 'bottom' indicate the distance of the top and bottom of the cursor from the top of the character cell, on a scale of 0 to 99. returns: nothing see also: hidecursor example: showcursor 0 99 // sets the cursor size to fill the entire char cell showcursor 50 99 // sets the cursor size to fill the bottom half of // the character cell showentry ────────────────────────────────────────────────────────────────────── remarks: Temporarily displays the screen as it appeared in DOS immediately before the editor was started.

Values of 5 through 200 may be specified. The default queue size is 20 when the editor is started. returns: Non-zero if successful, otherwise zero. see also: dispatch, process sortblock opt=[di] mark ────────────────────────────────────────────────────────────────────── remarks: Sorts marked lines. If 'mark' is not specified, the default markid is assumed. For column marks, the text between the left and right edges of the mark is used as the sort key. For all other marks, the entire line is used as the sort key. In either case, all lines spanned by the mark are sorted, not just the text within the mark. One of the following options may be specified: d - sort in descending order i - ignore case when sorting returns: TRUE if successful, otherwise null. speaker [0/1] ────────────────────────────────────────────────────────────────────── remarks: Enables (1) or disables (0) sound from the PC speaker. returns: nothing see also: beep splitline col row buffer ────────────────────────────────────────────────────────────────────── remarks: Splits one line into two lines in a buffer. If 'buffer' is null or not specified, then the current buffer is assumed. 'row' specifies which line is to be split and 'col' specifies the column where the split is to occur. If 'row' and 'col' are not specified, the current cursor position is assumed. All characters after, and including the specified column are moved to column 1 in a new line after the line to be split. returns: TRUE if successful, otherwise null. see also: delline, insabove, insline, joinline example: splitline // splits the current line at the cursor in the // current buffer splitline 10 // splits the current line at column 10 splitstr delimit+quote multistring ref1 ref2 ... ────────────────────────────────────────────────────────────────────── remarks: Splits an editor 'multistring' (created by the 'joinstr' function) into individual strings. The 'delimit' and 'quote' characters are used as delimiters and literal quoting characters to separate the string (see 'joinstr' above). If 'delimit' and 'quote' are not specified, then the default delimiter character is a slash (/) and the default quote character is a backquote (`). 'ref1', 'ref2', etc. refer to variables passed by reference which are to contain the resulting component strings (see the 'ref' keyword). returns: This function returns the number of component strings in the multistring. The actual component strings are returned in variables passed by reference to this function. see also: joinstr, ref example: splitstr '' "abc/def/xyz" ref a ref b ref c // returns 'abc' in a, 'def' in b, and 'xyz' in c. // the entire function call returns '3' splitstr "|\\" "abc|x\|yz" ref a ref b // returns 'abc' in a, and 'x|yz' in b. // the entire function call returns '2' splitwin opt=[hv] [Lib][edit] ────────────────────────────────────────────────────────────────────── remarks: Splits the current edit window.

This stops the automatic extension of the mark when the cursor is moved. If 'mark' is not specified, the default markid is assumed. returns: nothing see also: extendmark, markchar, markcolumn, markline, markstream example: markline // marks the current line stopmark // stop cursor extension of the mark sub searchstr replacestr string opt=[irwx] ────────────────────────────────────────────────────────────────────── remarks: Replaces all occurrences of 'searchstr' found in 'string' with 'replacestr'. Any of the following search options may be specified: i - ignore case r - search in reverse from the end of the string w - whole words only x - use regular expressions (see 'Regular Expression Searching') Specifying a null replace string will remove all occurrences of 'searchstr' within 'string'. returns: The new string resulting from the substitution of 'replacestr' for all occurrences of the search string. see also: pos, poschar, posnot example: sub 'p' '112' "apples" // returns 'a112112les' sub 'es' 'y' "apples" // returns 'apply' sub 'PL' '' "apples" 'i' // returns 'apes' submenu menuname [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays the specified menu as a submenu. This function is only intended for use within a pulldown menu. returns: nothing see also: getmenu, gotomenu, menu swapfiles swapfile1 swapfile2 swapfile3 ────────────────────────────────────────────────────────────────────── remarks: Defines swap files for the editor to use in low memory situations. If available, EMS and XMS memory will always be used before the swap files are created. 'swapfile2' will only be used when there is no room on the drive containing 'swapfile1', and 'swapfile3' will only be used when there is no room on the drive containing 'swapfile2'. All swap files should be on different drives.

Truncation can occur if <ctrl break> was pressed while loading the file. If 'buffer' is null or not specified, the current buffer is assumed. returns: TRUE if the buffer was truncated, otherwise null. see also: buffer? undo buffer ────────────────────────────────────────────────────────────────────── remarks: Reverses the changes made by the last undoable function (or group of functions marked with undobegin - undoend) for a specific buffer. If 'buffer' is null or not specified, then the current buffer is assumed. returns: TRUE if successful, otherwise null. see also: redo, undobegin, undoend undobegin ────────────────────────────────────────────────────────────────────── remarks: Marks the beginning of a group of function calls which are considered to be one 'undoable/redoable' editing operation. The group is terminated by a matching 'undoend' function. 'undobegin' and 'undoend' pairs may be nested. Undo/redo information for all undoable function calls within this group is saved as one undoable operation on the undo/redo stack for each operation's buffer. The follow types of editing functions are undoable: - functions which modify buffers - functions which create or modify marks - functions which create or modify text folds The current cursor position, window size, and window view, are also saved on the undo/redo stack. When the 'undo' or 'redo' functions are called, all undoable editing operations within the group are 'undone' together at one time. returns: nothing see also: redo, undo, undocursor, undoend example: undobegin // groups 3 editing operations delline // together as one undoable writetext "some text" // operation insline "new line" undoend undocursor buffer ────────────────────────────────────────────────────────────────────── remarks: Saves the current window size, window view, and cursor position on the undo/redo stack as one undoable operation. If 'buffer' is null or not specified, then the current buffer is assumed. returns: nothing see also: redo, undo, undobegin, undoend undoend ────────────────────────────────────────────────────────────────────── remarks: Marks the end of a group of undoable/redoable function calls started with the 'undobegin' function (see 'undobegin' above). returns: nothing see also: redo, undo, undobegin undosize size buffer ────────────────────────────────────────────────────────────────────── remarks: Sets the undo/redo stack size for a buffer to 'size' editing operations. If 'buffer' is null or not specified, the current buffer is assumed. Setting the undo/redo stack size to zero disables undo/redo for the specified buffer. The stack size determines the maximum number of undoable editing operations (single or group) that will be saved for each buffer. When an undoable operation is performed and the size limit is exceeded, the undo information for the least-recently performed operation is discarded. When a buffer is initially created, the undo/redo stack size is set to zero (undo is disabled). Whenever the undo/redo stack size is changed with this function, all previous undo/redo information for the buffer is erased. returns: nothing see also: redo, undo, undobegin, undoend example: undosize // disables undo for the current buffer undosize 200 // deletes the current undo stack and sets the undo // stack size for the current buffer to 200 // editing operations unsetx varexpression objexpression ────────────────────────────────────────────────────────────────────── remarks: Destroys the object variable defined by 'varexpression' in the specified object. If 'objexpression' is not specified, then the current object is assumed. returns: nothing see also: function?, lookup, set, setobj, setx, setxfun, setxobj example: unsetx "TempVar" unsetx "Temp" + "Var" "edit" up rows buffer ────────────────────────────────────────────────────────────────────── remarks: Moves the cursor upward. 'rows' specifies the number of lines to move. If 'rows' is not specified, 1 is assumed. If 'buffer' is null or not specified, the current buffer is assumed. returns: TRUE if successful, otherwise null. see also: down, left, right example: up // moves the cursor up 1 row up 5 // moves the cursor up 5 rows upcase string ────────────────────────────────────────────────────────────────────── remarks: Converts a string to uppercase. returns: the string in uppercase. see also: flipcase, locase example: upcase "peaches" // returns "PEACHES" usemark mark ────────────────────────────────────────────────────────────────────── remarks: Sets the default markid to 'mark'. If 'mark' is not specified, the markid '*' is assumed. When the editor is started, the default markid is '*'. returns: nothing see also: getmarkuse example: usemark 'T' // set the default markid to 'T' . . usemark // always set the default markid back to '*' videoborder color ────────────────────────────────────────────────────────────────────── remarks: Changes the video overscan border color to the specified color. returns: nothing see also: writebak videomode cols rows [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Changes the current video mode to 'cols' x 'rows'. 'cols' must be 40 or 80 and 'rows' must be 12, 14, 21, 25, 28, 43, or 50. returns: nothing see also: setvideo example: videomode 80 28 // change the video mode to 80 x 28 videomode 80 50 // change the video mode to 80 x 50 virtocol virtualX window ────────────────────────────────────────────────────────────────────── remarks: Converts a virtual screen X-coordinate to a column in a window. If 'window' is not specified, the current window is assumed. If 'virtualX' is not specified, the current mouse pointer position is assumed. returns: the window column. see also: virtorow example: say (virtocol) // displays the column in the current window where // the mouse pointer is located virtorow virtualY window ────────────────────────────────────────────────────────────────────── remarks: Converts a virtual screen Y-coordinate to a row in a window. If 'window' is not specified, the current window is assumed. If 'virtualY' is not specified, the current mouse pointer position is assumed. returns: the window row. see also: virtocol example: say (virtorow) // displays the row in the current window where // the mouse pointer is located window? window ────────────────────────────────────────────────────────────────────── remarks: Tests if a window exists. If 'window' is not specified, the current window is assumed. returns: TRUE if the window exists, otherwise null. see also: frame?, wintype? winlist [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays a list of open windows. If a window is selected, it becomes the current window. returns: nothing see also: currwin wintype? object window ────────────────────────────────────────────────────────────────────── remarks: Tests if the specified object is located in the inheritance path of the window event object. If 'window' is not specified, the current window is assumed. returns: TRUE if 'object' is located in the inheritance path of the window event object, otherwise null. see also: objtype? example: wintype? "edit_fmgr" // tests if the object 'edit_fmgr' is located in the // inheritance path of the window (tests if the // window is a fmgr window or an edit window) write string [Ext][edit,prompt] ────────────────────────────────────────────────────────────────────── remarks: Enters a string into the current buffer at the cursor position, and moves the cursor to the end of the string. If the cursor is in insert mode, the string is inserted into the text, otherwise the string is overlaid onto the text. This function is similar to the 'writetext' function. However, the 'write' function provides support for the following window settings: - Live Word Wrap - MatchCharacter - Standard Word Wrap - Translate returns: nothing see also: instext, ovltext, writetext example: write "some text" writebak string screencol screenrow color ────────────────────────────────────────────────────────────────────── remarks: Displays the specified string on the screen background. The string is displayed at physical screen coordinates 'screencol' and 'screenrow' using the color attribute 'color'. The coordinates are relative to the upper left corner of the screen. If 'screencol' or 'screenrow' are not specified, then the string is displayed immediately to the right of the last string written. If 'color' is not specified, the color of the last string is used. returns: nothing see also: hilite, writeline, writestr writefile handle string opt=[k] ────────────────────────────────────────────────────────────────────── remarks: Writes the specified string at the current position in the open file specified by 'handle'. The current position in the file is advanced by the number of characters written. If option 'k' is specified, the file date and time are not modified. returns: The number of characters written if successful, otherwise null. see also: closefile, filepos, openfile, readfile writeline string color col row ────────────────────────────────────────────────────────────────────── remarks: Displays the specified string in the current window using the color attribute 'color'. If 'col' and 'row' are not specified, the current cursor position is assumed. If 'color' is not specified, the window 'text' color is assumed (see 'setcolor'). The current cursor position is moved to column one of the next row. If the cursor was on the last row in the window, the window contents are scrolled up by one line. If the current window contains a buffer, the effects of this function (except for cursor movement) are temporary and will disappear the next time the display is updated. returns: nothing see also: clearwindow, getx, gety, gotoxy, hilite, writebak, writestr example: writeline "some text" // writes the string 'some text' at the cursor and // moves the cursor to the next line writeline "some text" 95 // writes the string 'some text' at the cursor with the // color white on magenta, and moves the cursor to // the next line writestr string color col row ────────────────────────────────────────────────────────────────────── remarks: Displays the specified string in the current window using the color attribute 'color'. If 'col' and 'row' are not specified, the current cursor position is assumed. If 'color' is not specified, the window 'text' color is assumed (see 'setcolor'). The current cursor position is moved one column past the end of the string. If the current window contains a buffer, the effects of this function (except for cursor movement) are temporary and will disappear the next time the display is updated. returns: nothing see also: clearwindow, getx, gety, gotoxy, hilite, writebak, writeline example: writestr "some text" // writes the string 'some text' at the cursor writestr "some text" 95 // writes the string 'some text' at the cursor with the // color white on magenta writetext string col row buffer ────────────────────────────────────────────────────────────────────── remarks: Enters a string into a buffer at the specified row and column, and moves the cursor to the end of the string. If the cursor is in insert mode, then the text is inserted, otherwise the text is overlaid. If 'buffer' is null or not specified, then the current buffer is assumed. If 'col' and 'row' are not specified, then the string is inserted at the current cursor position. returns: TRUE if successful, otherwise null. see also: delchar, ovltext example: writetext "some text" // writes 'some text' at the cursor in the current // buffer writetext "some text" 2 20 // writes 'some text' at column 2, line 20 in the // current buffer writetext "some text" 1 1 "abc" // writes 'some text' at column 1, line 1 in the // buffer "abc" yncbox message title [Lib][a] ────────────────────────────────────────────────────────────────────── remarks: Displays the specified message in a popup window with 'Yes', 'No', and 'Cancel' buttons. If a title is not specified, 'Message' is assumed. returns: The name of the button pressed (Yes, No, or Cancel), or null if no button was pressed. see also: msgbox, okbox, say, shortbox example: yncbox "Replace the string?" "Replace"
