It is intended for creating small (<64K byte) DOS text files, such as files containing batch commands, source code, or printer escape sequences. TED's features include: - Fast, full screen text editing with extensive cursor control. - Simple to use. Provides on-line help and shift-sensitive function key menus. Supports both function keys and WordStar commands. - Support for monochrome or color display adapters (in character mode) and screen sizes greater than 80x25. - Copying, deleting, or moving lines or blocks of texts. - Search and replace commands. - Undo capability. - Entry and display of all ctrl codes and full IBM character set. - Retrieving text from or writing blocks of text to other files. - Temporary return to DOS. - Small program file size (approximately 12K bytes). System Requirements: TED runs on IBM-compatible machines (PC,XT,AT) under DOS 2.0 or later. It operates in text mode with MDA, Hercules, CGA, EGA, or VGA display adapters. It requires at least one disk drive (floppy or hard) and 150K bytes of free RAM. Limitations: TED is not intended for editing large files or for sophisticated wordprocessing. File and buffer sizes are limited to 64K bytes. Line length is limited to 256 characters. Tabs are fixed at 8 column intervals. TED does not support word wrap. USAGE To start TED: TED TED FILENAME.EXT To exit TED (saving changes) or quit (without saving changes): Press F7 (EXIT) or F3 (QUIT/ABORT). Function key commands (F1-F10, Shift + F1-F10, Ctrl + F1-F10) are shown on the menu at bottom of the screen. The menu changes depending on whether the shift or ctrl key is depressed. Most WordStar non-document (N) mode control-key commands are supported as alternatives to the function keys. Help is available with the F1 key. When you exit TED and save the file being edited (F7), TED will prompt for the file name (or confirmation) if the file has been modified. File and buffer sizes are limited to 64K bytes.

(Note: The Num Lock key must be released to use the keypad keys on keyboards without a separate keypad.) Cursor commands are also available using the WordStar (WS) diamond of control-key commands. Keypad WS Function Up ^E Moves the cursor up one row. If the cursor is at the top of the screen, the display is scrolled down. Down ^X Moves the cursor down one row. If the cursor is at the bottom of the screen, the display is scrolled up. Left ^S Moves the cursor left one character. Right ^D Moves the cursor right one character. PgUp ^R Moves the cursor down one screen. PgDn ^C Moves the cursor up one screen. Home ^QS Moves the cursor to the start of the current line. End ^QD Moves the cursor to the end of the current line. Ctrl-Left ^A Moves the cursor left to the first letter of the previous word. Ctrl-Right ^F Moves the cursor right to the first letter of the next word. Ctrl-PgUp ^QR Moves the cursor to the top of the file. Ctrl-PgDn ^QC Moves the cursor to the end of the file. Ctrl-Home Scrolls the screen right eight columns. Use to see portion of line which extends off screen. Note: An inverse diamond in the last column of a row indicates that the line extends off screen. Ctrl-End Scrolls the screen left eight columns. ^W Scrolls the screen up one row. If the cursor is at the bottom of the screen, the cursor gets push up one row. ^Z Scrolls the screen down one row. If the cursor is at the top of the screen, the cursor gets push down one row. SPECIAL EDITING KEYS In addition to the cursor keys, the following keys are reserved for special editing functions: BS Erases the character to the left of the cursor. If the cursor is at the start of a line, the line is joined with the previous line. Del Deletes the character at the cursor position. If the cursor is at the end of a line, the line is joined with the following line. <CR> Inserts a new line in the file. The cursor is moved to the start of the new line. Any characters which were to the right of the cursor are moved to the new line. Ins Toggles between insert (I) and overstrike (O) modes. The current mode is displayed as an I or O at the end of unshifted function key menu at the bottom of the screen. Tab Inserts a tab character (ASCII 9) into file and advances the screen cursor to the next tab position. Tabs are fixed at eight column intervals; i.e., column 9, 17, 25, etc. Tabs are expanded as spaces when displayed or printed. Tabs can be displayed on screen by use of the CF4 (Show Tabs & EOLs) command. FUNCTION KEYS Most editing functions are accessed with the function keys, F1-F10, Shift F1-F10, and Ctrl + F1-F10, designated F#, SF#, and CF# below. The function key assignments are displayed on a menu line at the bottom of the screen. The menu changes depending on whether the Shift or Ctrl key is depressed. Most function keys have WordStar-compatible ctrl-key equivalents (shown in parenthesis below). F1 Help (^J) - Displays help consisting of tables of function key assignments, other editing commands, and ASCII/IBM character set. Use PgUp and PgDn to view; any other key resumes editing. SF1 Setup Options - Allows modifying TED parameters. Currently, supports only turning on/off creation of .BAK file. Other setup parameters, such as colors, can be modified thru the TED environment string (see note #1 below). CF1 Display Status Line - Shows line (L) and column (C) number of the cursor position, displayable char and hex code for the char at cursor, total number of lines (#L) and bytes (#B) in the buffer, and the file name (F); e.g., L=259 C=67 (a-61h) #L=538 #B=27506 F=TEST.TXT The status line is displayed above the menu line at the bottom of the screen and obscures the last line of text until it automatically disappears when the next key is struck. If the current line (cursor) would be hidden by status line, the screen is shifted up one line. F2 Find Forward (^QF) - Prompts for a search string (60 chars max) and searches the buffer forward from the cursor position for the next occurrence of the string. Case sensitivity works like in WordPerfect searches - uppercase chars in search string will match only uppercase, while lowercase chars will match both lower and uppercase chars. There is no option in TED to search backwards towards the top of file. SF2 Find Next (^L) - Searches forward for the next occurrence of the current search string. CF2 Find & Replace (^QA) - Prompts for a search string and a replace string and then searches for next occurrence of search string and ' replaces it (after confirmation) with the replace string. To confirm replacement, press R, Y, or <Enter>. To skip replacement, press S, N, or '. This command will automatically continue searching for the next occurrence until the command is exited via the <Esc> key. To automatically replace all occurrences of the search string from the current cursor position to the end of the file without confirmation, press A. To replace all occurrences of a string in a file (i.e., global replace), reposition the cursor to the beginning of the file (ctrl-PgUp) before invoking the replace command with the A option. F3 Quit [Abort] (^KQ) - Abort without saving edited text. Command prompts for confirmation that you want to abandon changes if the file was modified during the current editing session. SF3 Unused. CF3 Replace Next (^L) - Resumes the Find and Replace command starting at the current cursor position and using last settings of the search and replace strings (CF2). (Note: ^L functions as a CF2 or CF3 depending on whether a find (F2) or replace (CF2) was more recent.) F4 Mark/Unmark [Toggle] - Turns on/off text selection. Use the cursor commands to expand the marked block of text (displayed with highlight). Marked blocks are used with cut, copy, change case, print, write file commands. Deselect text by pressing F4 a second time. (Note: The paste, read file, and insert file commands also leave the text they insert highlighted. Unlike marked blocks, the highlights left by these commands are automatically removed by any subsequent keystroke. The inserted text is highlighted by these commands simply to show the user where the text was inserted and to permit the user to undo the command (by immediately cutting the highlighted text) if needed.) SF4 Change Case Marked - Changes case of marked block to all uppercase or all lowercase. If the block is not marked, the entire file will be converted. The original text is copied to the paste buffer to permit restoration if needed. To undo a case change, exit the change case function, delete the altered lines with the F8 key, and then restore the original lines with the paste (F6) function. CF4 Show Tabs & EOLs [Toggle] - Turns on screen display of Tabs and EOLs (CRLFs). Tabs are displayed as right pointing triangles and CRLFs are displayed as left pointing triangles. Useful for editing text which is formatted using Tab chars; e.g., .ASM files. F5 Cut Marked to PB - Moves the selected text to the paste buffer (PB). You must mark (F4) the block of text to be cut before using the cut command. After cutting text (F5), you may paste it (F6) as many times as you like or write it out to a separate file (F10). SF5 Copy Marked to PB - Copies selected text to paste buffer. Same as Cut (F5) except that the selected text is not removed from the edit/file buffer. CF5 Duplicate Char - Duplicates character at cursor position. Useful for duplicating characters which don't have corresponding keys on the keyboard; e.g., line drawing characters. F6 Paste - Inserts the contents of the paste buffer into the edit buffer at the cursor position. The inserted text appears highlighted on the screen and can be undone by immediately pressing F5 (Cut). Any other key will turn off the highlight. Use the Mark and Cut commands or Read File into PB to fill the PB before using the Paste command. The contents of the PB remain until overwritten by the next Cut, Copy, Change Case, Read File into PB, or ^KR commands. Therefore the Paste command can be used repeatedly to insert the same text if needed. SF6 Insert Character Code - Prompts for the ASCII code for a single char to be inserted in file. Code may be entered in decimal (0-255) or in hex (0h-FFh). Hex inputs must be terminated with an "H" or "h". CF6 Insert Ctrl Code - Allows a ctrl code to be entered into the file. Press CF6 followed by single ctrl key combination. For example, to insert page breaks (form feeds) into the file at the current cursor position, depress the Ctrl key and hit F6 followed by L (i.e., Ctrl-F6, Ctrl-L). (Note: This function works by disabling TED's normal WS ctrl-key processing for the next key.) F7 Save & Exit (^KX) - If file has been modified, prompts for name of file (or confirmation) for text to be saved in, writes the file, and exits TED. SF7 Print Marked on LPT1 - Prints marked text on printer LPT1. If no block is marked, the entire file is printed. Print can be aborted by pressing the <Esc> key. When done, Print leaves the block marked to permit additional copies to be made or the marked block to be adjusted. You must press F4 to unmark the block. CF7 Eject Page from LPT1 - Sends form feed to printer LPT1. F8 Delete Line (^Y) - Deletes the line the cursor is on. The line is saved in a one-line undo buffer and can be restored with the undelete line function (F9). The F8 and F9 keys can be used in concert to duplicate a line (press F8, F9, F9). SF8 Delete to EOL (^QY) - Deletes text from the current cursor position to the end of the current line. Deleted text is saved in the line undo buffer. CF8 Delete Word (^T) - Deletes characters from current cursor position up to start of next word (i.e., remainder of current word plus any intervening blanks leading up to first character in next word). Deleted words are saved in a 256 byte undo buffer and can be restored with the Undel Chars/Words (SF9, ^U) command. F9 Undelete Line - Copies contents of line buffer to the file buffer. Used in conjunction with delete line (F8) command. SF9 Undel Chars/Words (^U) - Restores characters or words which were deleted with Del (^G) or Delete Word (^T) commands immediately preceding the Undel Chars/Words command. Any other intervening commands will clear the contents of the undo buffer. Characters deleted with BS key are not saved in undo buffer. CF9 GoTo Line (^QI) - Moves cursor to a specified line number. The current line number can be determined by CF1 (Status) key. F10 Write PB to File - Writes the contents of the paste buffer to a file. Prompts for the file name. Use Mark and Cut to place desired text into paste buffer before using this command. Use for extracting a section of a file and saving it in a separate file or for saving the current version of an edited file without exiting the editor. (Note: The ^KS function is similar except that it combines the paste and write file function in a single command.) SF10 Read File into PB - Reads a file (<64K) into the paste buffer. You can then use the paste function to insert the text in the file being edited. (Note: The ^KR function is similar to this command except that it also automatically pastes the retrieved file from the paste buffer into the edit buffer.) CF10 GoTo DOS [Exec] - Suspends an editing session to allow execution of DOS commands. To return to the editing session, type EXIT at the DOS prompt. This function is useful for examining a directory or file, resizing the screen, or running another program from the command processor level. NOTES 1. You may setup TED parameters in an environment string. The string has 14 characters and a fixed format as shown below. Characters 5-10 set the three text colors used by TED (normal, inverse, and search). For example, SET TED=30MN1F703E0104 where Char 1-2 = 30 (version ID) Char 3 = M (Modify File) or V (View File Only) (Note: View only mode not implemented - use M.) Char 4 = N (No Backup) or B (Create .BAK file) Char 5-6 = Normal text color in hex (00-FF) Char 7-8 = Inverse/highlight color in hex (00-FF) Char 9-10 = Search/found color in hex (00-FF) Char 11-12 = Keyboard delay (00-03=250-1000 ms, FF=don't alter system KB delay and repeat rate Char 13-14 = Keyboard repeat rate (00-1F) lower val=faster and color = text attribute in hex. Note that the 8-bit text attribute is structured as follows: XBBBFFFFb where X=1 (blink), BBBb=background color (0-7), FFFFb=foreground color (0-F); e.g., 00011111b = 1F = Bright white text on blue background. 0 - Black 8 - Gray 1 - Blue 9 - Bright Blue 2 - Green A - Bright Green 3 - Cyan B - Bright Cyan 4 - Red C - Bright Red 5 - Magenta D - Bright Magenta 6 - Yellow/Brown E - Bright Yellow 7 - White F - Bright White In the above example, TED 3.0 is setup to be in modify (M) mode with No (N) .BAK file created. The colors are: Normal - Bright white text on blue background (1F) Inverse - Black text on white background (70) Search - Bright yellow on cyan background (3E). The keyboard typematic settings are 500 ms delay and 20 cps repeat rate. Keyboard delay and repeat rates can only be set with enhanced (AT) keyboards. If your machine is AT-compatible, you may wish to increase the keyboard repeat rate to make horizontal cursor movements more responsive (i.e., when holding the left or right arrow keys down). Keyboard rate can be set by using an external speedup utility before invoking TED or by setting the TED environment string. See note 4 below for related information. If no environment string is specified, TED will use default settings equivalent to SET TED=30MN1F703EFF04; i.e., same colors, etc. as in above example except that keyboard delay and repeat rates are left unchanged from the system setting. If you wish to change TED's default settings (e.g., colors), place a SET TED= statement in your AUTOEXEC.BAT file or in a separate batch file (EDIT.BAT) like the following: @ECHO OFF SET TED=30mn1e303f0104 (yellow on cyan) TED3 %1 Others: set ted=30mn0770f0ff04 (monochrome) 2. The preferred way of entering special character codes in TED is to use the SF6 (enter char code) or CF6 (enter ctrl char) functions. Char codes can also be entered by holding the Alt key down and typing the ASCII code (in decimal) on the numeric keypad and then releasing the Alt key. You cannot use this feature to enter control chars since codes <32 are interpreted by TED 3.0 as WordStar commands. 3. A diamond at the right edge of the screen indicates the line extends off screen. Press Ctrl-End to shift the visible portion of the lines to the left. Note: TED is designed to work with displays greater than 80x25. TED senses the display size when the program is started or whenever you resume editing after a CF10 command. If your display system supports text screens wider than 80 characters, you can dynamically resize the screen by using the GoTo DOS command (CF10) to exit to DOS, resize the display with the appropriate utility, and then resume editing (type EXIT at DOS prompt) with the wider screen. TED's screen resizing capability works well with Personic's UltraVision screen enhancer utility which enables text displays up to 132x60 on VGA and compatible EGA systems (ref. CIS:PCVENB). 4. TED writes directly to the screen. If you scroll up or down (by keeping the up or down arrow key depressed) at a rate too fast for your system to simultaneously process the keystrokes and the display, the display may lag. The display will catch up when you release the up or down arrow (or ^Z, ^W) keys. This effect is more likely to be seen on slow machines with fast keyboard repeat rates or when using larger screen sizes (more than 25 rows or 80 columns). The effect can be eliminated by reducing the keyboard repeat rate. 5. Lines are delimited with the CR-LF sequence. Note that CR-LF pairs are treated as a single character by TED. Pressing the Enter key will insert a CR-LF in the file; deleting an EOL will delete a CR-LF pair. An adjacent CR and LF cannot be separated. 6. TED does not place a CP/M-style EOF character (1Ah, ctrl-Z) at the end of the file when a file is saved. TED strips off any ctrl-Z characters from the end of a file when it reads a file. If you need to terminate a file with an EOF character, position cursor at the end of the file (ctrl-PgDn) and use the SF6 or CF6 command to enter the EOF code. 7. Under Windows or DESQview, run TED in full screen windows. 8. TED is written in assembly language (MASM). ERROR MESSAGES 1. Error - File too big (>64K) Files and buffers in TED are limited to 64K bytes. 2. Error - File read error 3. Error - Not enough memory TED needs approximately 150K of free RAM. 4. Error - Bad environment variable (SET TED=) Check format of TED environment string (see Note 1 above). GALLERY 1. The following example contains the line drawing characters for a box. Copy the following lines into a separate file by marking the box (F4) and saving the marked lines in a separate file (ctrl-KS). Then you can retrieve the file (ctrl-KR) and edit it whenever a box is needed. ┌───────────────────────────────────────────────────────────────────────┐ │ │ │ │ │ │ │ │ │ │ └───────────────────────────────────────────────────────────────────────┘ 2.
