::::BENCH_CONFIGURATION Configuring your system ═══════════════════════ The WCONFIG program is used to configure the InfoBench system. Additionally, specific tools may provide tool-specific configuration. The "Editor and Configuration" manual describes how to use the WCONFIG program. The following aspects may be configured: * screen colours (for colour monitors) * screen shades (for monitors which have shades of grey) * screen attributes (for monochrome monitors) * printers * what is displayed during file browsing ::::BROWSE_WINDOW Browsing Window ═══════════════ A browsing window is used to select or view items. The general format of the window is as follows: ┌──────────────title────────────────────┐ │ │ │ list of scrolling items │ │ │ │Escape=Cancel Enter=Select│ └───────────────────────────────────────┘ There will be a scroll bar (see <SCROLL_BAR>) on the right of the window if the number of items is greater than the capacity of the window. You can cancel the window by pressing the Escape (Esc) key. When the "Enter=Select" hotspot is present, you can select an item in the scrolling area by making that item the current item and then pressing the Enter key (the Enter key is ignored when the window is to be used for viewing only). You can change the current item by pressing the CURSOR-UP or the CURSOR-DOWN keys. When the scroll bar is present, the list of items will scroll in the window when you press the CURSOR-UP (CURSOR-DOWN) key when the current item is at the top (bottom) of the window. You can also display the next (last) window of items by pressing the PgDn (PgUp) keys. You can position to the start (end) of the list of items by pressing the Ctrl and PgUp (Ctrl and PgDn) keys simultaneously. If your computer has a mouse attached to it, you can use the scroll bar (see <SCROLL_BAR>) to reposition what is being displayed. You can select an item by pressing and releasing the leftmost button of the mouse while the mouse cursor is positioned within that item. ::::CHECK_FIELD Check Field ═══════════ A check field appears as follows: [ ] field name or [X] field name When there is an "X" between the square brackets, the field is true. It is false when there is a space between the square brackets. Setting a check field with the keyboard ═══════════════════════════════════════ You can set a check field by positioning to that field and then pressing the space bar. Setting a check field with the mouse ════════════════════════════════════ You can set a check field by clicking the mouse while the mouse cursor is within that field. The check field becomes the current field. ::::DIRECTORY_BROWSE Directory Browser ═════════════════ A directory can be selected using a Directory Browsing window which appears as follows: ┌───────────────────────────────────────┐ │ Directory Field │ ├───────────────────────────────────────┤ │ │ │ │ │ Scrolling list of directories │ │ │ │ │ │Escape=Cancel .... Enter=Select│ └───────────────────────────────────────┘ Initially, the cursor is positioned at the start of the scrolling directory field at the top of the form. This field contains the current directory to be selected. You can switch between the directory field and the scrolling area by using the TAB key. You can press the Escape (Esc) key to cancel the directory browser. You can press the F2 function key to receive a list of the drives on your computer (see <DRIVE_BROWSE>). You can select one of these drives to become the drive from which directories are displayed by the directory browser. Directory Field ═══════════════ The directory name that is displayed in the directory field determines the directory to be selected. When the directory browser was initiated from the file browser, the directory field will contain the name of the directory from which files were being displayed by the file browser. You select this directory by pressing the Enter key when the current field is the directory field. You can type a DOS directory name (see <DIRECTORY_NAME>) in this field or you can select one of the directories in the scrolling area to be placed in this area. Scrolling Area ══════════════ The scrolling area shows the directories on the current drive. The scrolling area scrolls in the usual way using the cursor keys, PgUp (display previous page), PgDn (display next page), Ctrl/PgUp (display, starting at beginning), and Ctrl/PgDn (display, last portion). The directories are shown with lines preceding them to denote the hierarchical structure of the sub-directories. Each line corresponds to one sub-directory. You can select a directory in the scrolling area by pressing the Enter key when that directory name is the current field. The full directory name will be copied to the directory field which will become the current field. Mouse ═════ If there is a mouse attached to your computer (see <MOUSE>), then you can position to the directory field by pressing and releasing the leftmost mouse button while the mouse cursor is positioned on that field. If you press and release the mouse while the mouse cursor is positioned on a directory in the scrolling area, then that directory will be selected into the directory field. You can also use the mouse in conjunction with the scroll bar (see <SCROLL_BAR>) to change the directory names displayed in the scrolling area. If you "double-click" on a directory field, then that directory will be the one selected. You "double-click" the mouse by pressing and releasing the leftmost mouse button two times, within a short time interval. ::::DIRECTORY_DIALOGUE Directory Dialogue ══════════════════ The directory window contains fields for the device and directory for which files are to be displayed in the file browsing window. You can change these fields. When you press Enter, the window will disappear and file names from the new directory will appear. If you press the Esc (escape) key, the window is cancelled and the directory from which files are displayed is unchanged. Directory browsing ══════════════════ Alternately, you can reset the device and directory fields by using the path browser (press F2) or the directory browser (press F3). The directory browser shows a full tree representation of the directories on the current disk drive (see <DIRECTORY_BROWSE>). The path browser shows only the path to the current directory and the sub-directories found within the current directory (see <PATH_BROWSE>). If you have many directories on your disk drive, you may find excessive the time that is required to build the full display shown by the directory browser (all directories on the drive need to be read). ::::DIRECTORY_NAME Directory names ═══════════════ Valid directory names have the following format: [ drive: ] [\] [ name ] [ \name ] ... [ \name ] where "name" is an existing sub-directory name. Some examples are: C:\PROJECT1 C:\PROJECT1\DATA C:\PROJECT1\DATA\BUDGET When the drive is omitted, the current drive is used. The following names are equivalent to the preceding names when the current drive is "C": \PROJECT1 \PROJECT1\DATA \PROJECT1\DATA\BUDGET When there is no "\" preceding the first sub-directory name, the entered sub-directories are assumed to be sub-directories of the current working directory on the indicated drive. Thus, if the current working directory on drive "C" is "PROJECT", then the three directories could have been given as: C: C:DATA C:DATA\BUDGET The special directory named "." ═══════════════════════════════ With DOS, each drive has a special directory termed the "current working directory" to which file names apply when there is no path specification preceding the file name. This directory can be referenced by ".". Thus, if your current working directory is C:\PROJECT1\DATA, then, the following are equivalent: . C:\PROJECT1\DATA .\JUNE C:\PROJECT1\DATA\JUNE The special directory name ".." ═══════════════════════════════ When ".." is used as a directory name, then, it refers to the parent directory of in the directory path to that point (or the parent directory of the current directory at the start). Thus, the following are equivalent when the current directory is C:\PROJECT1\DATA .. C:\PROJECT1 ..\REPORT C:\PROJECT1\REPORT ..\..\PROJECT2\DATA c:\PROJECT2\DATA ::::DOS_SERVICES DOS Services ════════════ The Control menus all contain an item "DOS Services" which, when chosen, causes the following actions to occur: * the current application is suspended * the DOS command interpreter is activated * DOS commands can now be entered The current application resumes when the DOS "EXIT" command is entered. ::::DRIVE_BROWSE DRIVE_BROWSE ════════════ A drive is selected using a Drive Browsing window which appears as follows: ┌───────────────────────────────────────┐ │ current drive │ ├───────────────────────────────────────┤ │ │ │ │ │ scrolling list of drives │ │ │ │ │ │Escape=Cancel Enter=Select│ └───────────────────────────────────────┘ Initially, the cursor is positioned at the drive field at the top of the form. This field contains the current drive to be selected. You can switch between the drive field and the scrolling area by using the TAB key. You can press the Escape (Esc) key to cancel the drive browser. When the drive is for removable media (such as a diskette drive), the text "-removable" is shown following the drive letter. Otherwise, the volume identification for that drive is displayed. Drive Field ═══════════ The drive name that is displayed in the drive field determines the drive to be selected. When the drive browser is initiated from the directory browser, the drive field will contain the drive for which directories were being displayed. You select this drive by pressing the Enter key when the current field is the drive field. You can type a valid DOS drive letter in this field or you can select one of the drives in the scrolling area to be placed in this field. Scrolling Area ══════════════ The scrolling area shows the drives on your computer. The scrolling area scrolls in the usual way using the cursor keys, PgUp (display previous page), PgDn (display next page), Ctrl/PgUp (display, starting at beginning), and Ctrl/PgDn (display, last portion). You can select a drive in the scrolling area by pressing the Enter key when that drive is the current field. Drive names are followed by: - removable (for diskette drives) volume label (for hard disk drives) Mouse ═════ If there is a mouse attached to your computer (see <MOUSE>), then you can position to the drive field by pressing and releasing the leftmost mouse button while the mouse cursor is positioned on that field. If you press and release the mouse while the mouse cursor is positioned on a drive in the scrolling area, then that drive will be selected into the drive field. You can also use the mouse in conjunction with the scroll bar (see <SCROLL_BAR>) to change the drive names displayed in the scrolling area. If you "double-click" on a drive field, then that drive will be the one selected. You "double-click" the mouse by pressing and releasing the leftmost mouse button two times, within a short time interval. ::::FILE_BROWSER ->FileBrowser ::::FILE_DISPLAY_OPTIONS Setting the display options for the File Browser ════════════════════════════════════════════════ Display options ═══════════════ Display options are check fields (see <CHECK_FIELD>) which determine what can be displayed about a file name. When the option is true (an "X" is shown), the file browser will display the corresponding information for each file. The options are: Time: the time that the file was last updated Date: the date that the file was last updated File Size: the size of the file Attribute: the file attributes Description: a file description for the extension Attributes are shown as letters where A: file has not been archived R: file is read/only Descriptions are based upon the file extension and indicate the probable use of that file. For example, the WP word processor uses files with an extension of "DOC" and the WATCOM Spreadsheet uses an extension of "WSS". Directory Browsing ══════════════════ There are three radio buttons (see <RADIO_BUTTON>) to determine what type of directory browsing should be obtained from the file browsing window: Path Browsing (see <PATH_BROWSE>) Directory Browsing (see <DIRECTORY_BROWSE>) Directory Dialogue (see <DIRECTORY_DIALOGUE>) File Pattern ════════════ The window also contains a field for the file pattern used to select file names to be displayed. This field shows the pattern used to restrict the files to be displayed. An application may set a pattern to restrict the display to only files with a particular file extension. You can change this pattern if you wish only certain files to be displayed. A pattern "*.*" will cause all files to be displayed. A file name consists of up to eight characters followed by an optional period and an optional file extension of up to three characters. Some valid file names are: MYDATA MYDATA.DAT BUDGET.DAT MORE.DAT A file name which matches the pattern will be displayed. The pattern can contain special characters "?" and "*". Characters in the pattern and the file name are compared one at a time according to the following rules: (1) A "?" matches any character in a file name. (2) A "*" causes the remaining characters in a file name or extension to match. (3) Any other character must match the corresponding character in the file name. Some examples are: *.* *.dat mydata.* m*.dat m?data.* MYDATA match match match MYDATA.DAT match match match match match MODATA.DAT match match match match BUDGET.DAT match match MONDAY.DAT match match match Include sub-directories in Browse window ════════════════════════════════════════ When this check field (see <CHECK_FIELD>) is set (an asterisk (*) appears), the parent directory (unless you are at the root of the device) and any sub-directories will be displayed in the scrolling area of the file browser. The parent directory is shown as: * parent directory and a sub-directory "XXXX" is shown as * sub-directory: XXXX Remember last directory browsed. ════════════════════════════════ When this check field (see <CHECK_FIELD>) is set (an asterisk (*) appears), the system will remember the directory in which you were browsing. This directory will be used as the starting directory the next time that the file browser is activated during your current session. When the field is not set, the initial directory is your current working directory. Configuration ═════════════ The Infobench configuration program (WCONFIG) can be used to configure the file browser for all WATCOM tools (see <BENCH_CONFIGURATION> for a description. ::::FileBrowser File Browser ════════════ A file is selected using a File Browsing window which appears as follows: ┌───────────────────────────────────────┐ │ current file │ ├───────────────────────────────────────┤ │ │ │ │ │ scrolling list of files │ │ │ │ │ │Escape=Cancel .... Enter=Select│ └───────────────────────────────────────┘ Depending upon the application that is displaying the browsing window, there may be extra fields at the top of the window and/or extra fields before the hot spots at the bottom of the window. You can cancel the file selection process by pressing the Escape (Esc) key. Initially, the cursor is positioned at the start of the scrolling file field at the top of the display window. You can switch between the file field and the scrolling area by using the TAB key. You can press the F2 function key to obtain a window in which you can change the directory from which files are displayed. Depending upon how file browsing is configured, one of the following hotspots will be shown at the bottom of file-browsing window: F2=Set-directory (see <DIRECTORY_DIALOGUE>) F2=Path-Browsing (see <PATH_BROWSE>) F2=Direct.-Browsing (see <DIRECTORY_BROWSE>) You can press the F3 function key to receive a window in which your current file-display options are listed (see <FILE_DISPLAY_OPTIONS>). You can change these options to * alter the format of file entries which are displayed * set the method to change directories * remember the last browse directory * include or exclude sub-directories in the scrolling area * restrict the displayed file names to match a given pattern The Infobench configuration program (WCONFIG) can be used to configure the file browser for all WATCOM tools (see <BENCH_CONFIGURATION> for a description. File Field ══════════ The file name that is displayed in the file field determines the file to be selected. Initially, this field is blank. You select this file by pressing the Enter key when the current field is the file field. You can type a valid DOS file name in this field or you can select one of the files in the scrolling area to be placed in this area. Scrolling Area ══════════════ The scrolling area shows any files in the current directory which match the file pattern. The file pattern is described in <FILE_DISPLAY_OPTIONS>. The scrolling area scrolls in the usual way using the cursor keys, PgUp (display previous page), PgDn (display next page), Ctrl/PgUp (display, starting at beginning), and Ctrl/PgDn (display, last portion). You can select a file name in the scrolling area by pressing the Enter key when that file name is the current field. The file name will be copied to the file field which will become the current field. If the file browser is configured to include sub-directories within the scrolling area, then selecting one those directories will change the directory from which files are displayed. Mouse ═════ If there is a mouse attached to your computer (see <MOUSE>), then you can position to the file field by pressing and releasing the leftmost mouse button while the mouse cursor is positioned on that field. If you press and release the mouse while the mouse cursor is positioned on a file in the scrolling area, then that file will be selected into the file field. You can also use the mouse in conjunction with the scroll bar (see <SCROLL_BAR>) to change the file names displayed in the scrolling area. If you "double-click" on a file field, then that file will be the one selected. You "double-click" the mouse by pressing and releasing the leftmost mouse button two times, within a short time interval. ::::HelpAboutHelp How to use the HELP System ══════════════════════════ You are now looking at Help text which can be used to help you understand the particular component that you are now using. When the text is too long to be displayed, you can view the next screenful by pressing the key labelled "PgDn" or "Page Down". Similarly, the preceding screenful can be viewed by pressing "PgUp" or "PageUp". Sometimes the Help text contains references to other text such as <INDEX> which will allow you to obtain Help about another topic (in this case, to display the index of help topics for your current software package). When there is only one such reference visible on the screen, pressing the Enter key will cause that Help topic to be displayed. When there is a number of references, the current topic will be displayed when the Enter key is pressed. You can change the current topic by successively pressing the TAB-FORWARD, TAB_BACKWARD, or any of the cursor-positioning keys (denoted with arrows on your keyboard). While Help text is being displayed, you can obtain this Help text by pressing the F1 key. Similarily, if you press the F2 key, then an index for your software will be displayed. When you have displayed more than one topic, you can switch from topic to topic by pressing the F3 (view the next topic) or the F4 (view the last topic) keys. If your computer has a mouse attached to it, the mouse can be used in the Help system, with the scroll bar on the right (see <SCROLL_BAR>) or to select a topic (press and release the leftmost button of the mouse while the mouse cursor is located on the topic). A scroll bar is visible only when the current topic is too long to be displayed on the screen. ::::HelpMenu How to use the InfoBench ════════════════════════ If you do not know how to use the Help system, press the Help key (F1) and a description of how to use Help will be displayed. Across the top of your screen you will see the menu bar which consists of a number of menu names (the first menu is "Control"). There is a number of actions available for each of these menus. If you wish to learn more about how to use the menus, see <MENUS>. You can learn more about this application by examining the information for the topics in the index (press F2 to obtain the index) or by selecting the "Help" item in "Control" menu. There may also be information that is specific to your installation. See <INSTALLATION_HELP> for details. ::::HOT_SPOTS Hot spots are areas on the screen which contain text indicating function keys or special keys such as Escape or Enter. You can see a number areas at the bottom of the area for this help text. If you have a mouse, clicking the mouse on a hot spot is equivalent to pressing the indicated key. If you don't have a mouse, then these areas cannot be used (instead, use the indicated keys from the keyboard to activate the function). ::::MENUS How to use Menus ════════════════ When you start an application, you are presented with a "menu bar" on the first line of the screen. Each of the names on that line represents a menu of actions that you can request. Using the keyboard ══════════════════ You can activate the menu bar by pressing and releasing the Alt key. You can then cycle through the menu names on the menu bar by pressing the cursor-right or cursor-left keys. You can deactivate the menu bar by pressing the Escape key. When the menu bar is active, each name has a unique "hot letter" which is high-lighted within the menu-bar name. If you press the key for one of those letters, the associated menu will be pulled down. When the menu bar is active, you can also pull down a menu by pressing any of the cursor-down, cursor-up, or Enter keys. When a menu is pulled down, you can then cycle through the menus by pressing the cursor-right or cursor-left keys. When a menu is first pulled down, the first item in the menu is highlighted to indicate that it is the current item. You can press the cursor-down or the cursor-up keys to change the current item. If you wish to cancel the menu-selection process, press the Escape key (Esc) and the current menu will disappear. If you wish to select one of the actions, use the cursor-up and/or cursor-down keys to make that action the current item (the high-lighted one) and then press the Enter key. Alternatively, you can type the "hot letter" which is high-lighted within the menu item. Using the mouse (see also <MOUSE>) ══════════════════════════════════ The menu for an item on the menu bar will be pulled down when you press the leftmost mouse button while the mouse cursor is within that item, and then drag downwards (without releasing the mouse button ). To select an item from the menu, drag the mouse (move the mouse without releasing the mouse button) so that the mouse cursor is within the item to be selected and then release the mouse button. If you drag the mouse to another menu name on the menu bar, then the menu for the new name is pulled down. The menu for the old name will disappear. If you decide that you wish to cancel the menu-selection process, be careful to release the mouse button while the mouse cursor is not positioned within either the menu bar or within a menu. If you wish to pull down a menu, press and release the leftmost mouse button, while the mouse cursor is within that menu name on the menu bar. If you wish to cancel a pulled-down menu, press and release the leftmost mouse button, while the mouse cursor is within the name of the menu on the menu bar. ::::MOUSE Using the Mouse ═══════════════ General Information ═══════════════════ The mouse is a pointing device. As you move the mouse, the mouse cursor (a rectangular box) will move correspondingly about the screen. Moving the mouse, without pressing any of the button(s) on it has no effect except to move the mouse cursor. The first mouse button (the leftmost one) or the only one, depending upon the particular mouse that you have, is used to signal the pointing interaction. When you press the button, you are starting a mouse interaction that is completed when you release that button. The particular interaction depends on the location of the mouse cursor when you press the mouse. The term "click the mouse" means to press and then to immediately release the leftmost button on the mouse without moving it. Typically, you click the mouse to select an item, to invert the value of a check field (see <CHECK_FIELD>), or to set a radio button (see <RADIO_BUTTON>). The term "drag the mouse" means to move the mouse while the mouse button is depressed. Typically, you drag the mouse while a mouse interaction is not yet complete. Using the mouse with menus (see also <MENUS>) ═════════════════════════════════════════════ The menu for an item on the menu bar will be pulled down when you press the leftmost mouse button while the mouse cursor is within that item, and then drag downwards (without releasing the mouse button ). To select an item from the menu, drag the mouse (move the mouse without releasing the mouse button) so that the mouse cursor is within the item to be selected and then release the mouse button. If you drag the mouse to another menu name on the menu bar, then the menu for the new name is pulled down. The menu for the old name will disappear. If you decide that you wish to cancel the menu-selection process, be careful to release the mouse button while the mouse cursor is not positioned within either the menu bar or within a menu. If you wish to pull down a menu, press and release the leftmost mouse button, while the mouse cursor is within that menu name on the menu bar. If you wish to cancel a pulled-down menu, press and release the leftmost mouse button, while the mouse cursor is within the name of the menu on the menu bar. Using the mouse with Hot Spots ══════════════════════════════ Hot spots are areas on the screen which contain text indicating function keys or special keys such as Escape or Enter. You can see a number areas at the bottom of the area for this help text. If you have a mouse, clicking the mouse on a hot spot is equivalent to pressing the indicated key. If you don't have a mouse, then these areas cannot be used (instead, use the indicated keys from the keyboard to activate the function). Using the mouse while editing ═════════════════════════════ If you click the mouse on an editable field into which data can be typed, the keyboard cursor is positioned to the field. The keyboard position is identical to the position of the mouse cursor if there is a non-blank character at that position or to the right of that position; otherwise, the keyboard cursor is positioned immediately following the right-most non-blank character. If you click the mouse on a check field, the value of the field is changed. A check field is preceded by "[X]" to indicate that the value is true and by "[ ]" to indicate a false value. See <CHECK_FIELD> for more details. If you click the mouse on a radio button, that button becomes the active button (and the previous active button becomes inactive). The active radio button is indicated by "(*)" at the start of the field; other buttons in that set of radio buttons will start with "( )". See <RADIO_BUTTON> for more details. In these cases, you don't actually have to click the mouse, although this is what you would normally do. To be more precise, you must press the mouse button while the mouse cursor is within the framed window containing the field in question. The button is released while the mouse cursor is within the field in question (the mouse could have been dragged to that field). ::::PATH_BROWSE Path Browser ════════════ A directory can be selected using the Path Browsing window which appears as follows: ┌───────────────────────────────────────┐ │ current directory │ ├───────────────────────────────────────┤ │ │ │ │ │ scrolling list of directories │ │ in path │ │ │ │Escape=Cancel .... Enter=Select│ └───────────────────────────────────────┘ Initially, the cursor is positioned at the start of the scrolling directory field at the top of the form. This field contains the current directory to be selected. You can switch between the directory field and the scrolling area by using the TAB key. You can press the Escape (Esc) key to cancel the path browser. You can press the F2 function key to receive a list of the drives on your computer (see <DRIVE_BROWSE>). You can select one of these drives to become the drive from which directories are displayed by the directory browser. Directory Field ═══════════════ The directory name that is displayed in the directory field determines the directory to be selected. When the path browser was initiated from the directory window, the directory field will contain the name of the directory on the drive displayed on that window. You select this directory by pressing the Enter key when the current field is the directory field. You can type a DOS directory name (see <DIRECTORY_NAME>) in this field or you can select one of the directories in the scrolling area to be placed in this area. In either case, the display will change to reflect the path selected. Scrolling Area ══════════════ The scrolling area shows the path to the directory in the directory field and the sub-directories of that directory. If you select any of the directories that are displayed, that directory replaces the directory in the directory field and the scrolling area is re-drawn for the selected directory. Thus, with successive selections, you can quickly change the displayed path and locate the directory for which you are searching. The scrolling area scrolls in the usual way using the cursor keys, PgUp (display previous page), PgDn (display next page), Ctrl/PgUp (display, starting at beginning), and Ctrl/PgDn (display, last portion). Mouse ═════ If there is a mouse attached to your computer (see <MOUSE>), then you can position to the directory field by pressing and releasing the leftmost mouse button while the mouse cursor is positioned on that field. If you press and release the mouse while the mouse cursor is positioned on a directory in the scrolling area, then that directory will be selected into the directory field and the scrolling area will be re-drawn. You can also use the mouse in conjunction with the scroll bar (see <SCROLL_BAR>) to change the directory names displayed in the scrolling area. If you "double-click" on a directory field, then that directory will be the one selected. You "double-click" the mouse by pressing and releasing the leftmost mouse button two times, within a short time interval. ::::RADIO_BUTTON Radio Buttons ═════════════ A set of radio buttons appears as follows: ( ) button-1 ( ) button-2 . . . ( ) button-N The fields may be arranged horizontally, vertically, or in a rectangle, depending upon their usage in a particular window. At most one of the fields is true and is preceded by (*). When you set a radio button to be true, the button that was previously true is set to be false. When you cycle through the fields on a form using the TAB keys, only the current radio button (the one which is true) is visited. When the current field is a radio button and the buttons occur on more than one line, then the CURSOR-UP and the CURSOR-DOWN keys will cycle around the set of radio buttons in a vertical manner. When the current button is on a line containing more than one button from the current set, then the CURSOR-RIGHT and CURSOR-LEFT keys will cycle around the buttons in the current set on that line. The current radio button is always set to be true. Setting a radio button with the keyboard ════════════════════════════════════════ You can set a radio button by positioning to that field. Setting a radio button with the mouse ═════════════════════════════════════ You can set a radio button by clicking the mouse while the mouse cursor is within that radio button. The radio button becomes the current field. ::::SCROLL_BAR Scroll Bars ═══════════ A scroll bar is used when the information to be displayed is too large to fit in a display area. A scroll bar can be vertical (displayed up and down) when the information is too long and can be horizontal (displayed left and right) when the information is too wide. The bar contains two symbols (called icons) at each end plus an area in the middle which contains a slider that is used to indicate the relative position of the information being displayed to the total information. When the display area is too small, the middle area and the page-up and page-down icons may be eliminated from the scroll bar. If your computer does not have a mouse attached to it, the scroll bar is for display purposes only: it will indicate the relative position of the text being displayed. You can reposition the display text by pressing the PgUp, PgDn (TAB-FORWARD, TAB-BACKWARD) and the cursor-positioning keys (denoted with arrows on the keyboard). When you can use a mouse, the scroll bar can be used to reposition the information being displayed. First, you must press the leftmost button of the mouse while the mouse cursor is located on the scroll bar. The position of the mouse cursor when you release the mouse, determines the repositioning. If the mouse cursor is not on the scroll bar at this point, no repositioning will take place. If the cursor is on the first icon at the top (left) of the scroll bar, the information will scroll down (right) one line (column). If the cursor is on the first icon at the bottom (right) of the scroll bar, the information will scroll up (left) one line (column). If the cursor is on the second icon at the top (left) of the scroll bar, the information will scroll down (right) by the size of the display area. If the cursor is on the second icon at the bottom (right) of the scroll bar, the information will scroll up (left) by the size of the display area. If the cursor is in the middle area of the scroll bar, the slider is positioned to indicate the position of the information to be displayed when the mouse button is released. ::::SELECT_PRINTER Select current printer ══════════════════════ The current printer is the device to which printed output is directed. The InfoBench system can be configured to have more than one such printer if there is more than one printer attached to your computer. A physical printer can also be configured in a number of different ways. The printer selection window shows the names of printers that have been configured as a list of radio buttons (see <RADIO_BUTTON>). The current printer is the one with "(*)" at the start of the name. You can change the radio button to another printer by making that field the current field and then pressing the space bar. If there is a mouse attached to your computer, you can accomplish the same by positioning the mouse cursor within the field and then pressing and releasing the leftmost mouse button. The current printer is changed (and the selection window is removed) when you press the Enter key. If you press the Esc (escape) key, the selection window is cancelled and the current printer will be unchanged.
