VDE.REF ------- Reference Manual for the VDE Editor: version 1.62 (27 Oct 1991) (c)1987-91, E. Meyer ================================ CONTENTS ================================== 1. SYNTAX. How to invoke VDE from the DOS command line. 2. COMMAND SUMMARY: MenuBar choices; command keystrokes. 3. VDE REFERENCE, alphabetically by topic: Accessory files, Auto format, Auto indent, Auto number, Auto save, Block commands, Deleting, Envelopes, Files, Find/replace, Foreign characters, Graphics, Header, Hyphenation, Information, Inserting, Justification, Line spacing, Margins, Matching files, Moving around, Multiple files, Page preview, Pagination, Paragraph indent, Place markers, Print styles/codes, Printer drivers, Printing, Proportional spacing, Reformat, Ruler line, Run command/shell, Save/exit, Screen controls, Screen size, Splitting files, Tabs, Time/date, Undelete, Upper/lower case, Windows. 4. MACROS. Explanation and examples of: Function keys, Key redefinition files, Macro definition and use, Macro keys, Macro programming, Toggle control, Recording macros. ================================ 1. SYNTAX ================================ TO RUN VDE, you can just type "VDE", with no arguments; or, you may specify a list of up to 8 filenames. Any filename may include a DOS directory, and/or be followed by a mode option. Spaces or a comma may be used to separate filenames. A key definition or printer driver file may also be specified at the end of the command line, following a semicolon ";". vde {filename} {/m} {{,} filename2 {/m}} {...} {;name.VD_} {;name.VD_} EXAMPLES: vde vde article.doc/w;ws4.vdf vde sample.fil vde b:myfile,myfile.bak vde a:summary \wp\memo vde prog.doc/a prog.asm/n errors "filename" - file to edit. If no name is given, you begin a new (untitled) file. With multiple names, the previous item's directory carries over to the next item, unless this begins with a new drive or root "\". (In the example above, MYFILE.BAK is on drive B:.) "/m" or " m" - optional choice of file modes: "m" can be "A"SCII, "W"ordstar, WordStar "5", Word"P"erfect, "X"yWrite/NotaBene, "M"icrosoft Word, or "U"nformatted document; or "C"-source or "N"ondocument. Normally defaults to "/A". Must be separated from filename by space and/or slash. ";name.VD_" - optional utility file(s) to load, must have file type .VDF, VDK, .VDP, .VDC, or .VDG. Files must reside in the specified, current, or VDE directory. See ACCESSORY FILES. =========================== 2. COMMAND SUMMARY ============================= Explanation of Keys: special IBM PC keys are indicated in [brackets], including arrows [^,v,<,>] for the cursor keys. [+] and [-] refer to the keypad +,- keys only. "Esc" indicates pressing the Escape key, [Esc]; "Esc1" means [Esc],1. "Alt" indicates holding down the [Alt] key: "AltD" means [Alt]+D. "^" indicates holding down the [Ctrl] key: "^K" means [Ctrl]+K. Many commands use two-key sequences, like ^QR = [Ctrl]+Q,R. The prefix (^Q) displays in the header, and can be canceled by pressing [Esc] or [Space]. If you have an "enhanced" or nonstandard keyboard, you may want to remap the functions of the [Ctrl,Alt] keys; see CONTROL KEY (VKMAP). If your keyboard lacks any of the IBM PC keys, equivalents are always available (e.g., ^R for [PgUp]). If you have no [Alt] key, you can still access the Alt-commands with a double-Esc prefix: Esc,Esc,X = AltX. SPECIAL KEYS [Enter] = Carriage Return (also CR, or ^M). New line. In documents, marks a paragraph end. [Tab] = Hard Tab mode: enter Tab. Variable Tab mode: move to next stop. Shft[Tab] = backward variable Tab: move to previous stop. [BkSp] = BackSpace (also BS or ^H). [May instead delete to left.] [Del] = Delete character to left. [May instead delete at cursor.] ^[BkSp] = delete character to left. [May instead delete word to left.] [Ins] = toggle Insert on and off. ^[Ins] = Word Insert on/off. [^], [v], [>], [<] (arrow keys) = move cursor. ^[<],^[>] = move to start of previous (left), next (right) word. ^[^],^[v] = go to top, bottom of screen. (AT keyboard only) [5] = make current line center of screen. (Keypad keys, [-],[+] = scroll back, forward one line. NumLock off) [Home],[End] = go to beginning, end of line. Repeat: prev/next line. [May instead go to top/bottom of screen.] ^[Home],^[End] = move to top, end of file. [PgUp],[PgDn] = page back, forward one screen. ^[PgUp],^[PgDn] = page both windows of split screen back, forward. Shft[^],[v],[>],[<] \ (shifted arrow/keypad keys) Shft[Home,End,PgUp,PgDn] / mark block MENU-BAR MODE Press [Esc] to call up the main menu bar; select a sub-menu by typing the capitalized, highlighted letter, then select a command from it. The [Esc] key can be used to return to the main menu, or (from the main menu) to return to editing.

VDE REFERENCE =============================== ACCESSORY FILES (AltU) - AltU allows you to change many VDE settings by using (loading and saving) specific types of data files. .VDF/K files can be Loaded and Saved - see KEY DEFINITION FILES. .VDG files can be Loaded and Saved - see GRAPHICS (CHARACTERS). .VDP files can be Loaded - see PRINTER DRIVERS. .VDC files can be Loaded - see CHARACTER WIDTHS. Each of these may also be loaded with a semicolon on the command line (see SYNTAX). Files must be in either the specified, current, or VDE directory (specified with the SET command -- see DIRECTORIES). AUTO FORMAT (^OM) - When on, continuously keeps the paragraph of text you are working on properly formatted (margins and spacing), even as you add to or delete from the line; format changes are implemented instantly. When off, the manual ^B command can still be used (see REFORMAT). [Default status can be chosen.] Care must be taken in files with mixed formats, as the CURRENT settings of margins and spacing are always used. Note that with Auto Format on, certain keystrokes may have additional (or no) effects, due to the instant reformatting afterward. AUTO INDENT (^OA) - When on, wordwrap or the [Enter] key will cause the cursor, upon moving to the next line, to indent to match any existing indentation on that line (with insert OFF) or the previous line (with insert ON). Thus any structured indentation you create is maintained. Useful as a temporary (paragraph) indent, or for outlines, program source code, etc. Works in all modes, including non-document. Note: Indentation must be done with spaces or variable tabs, NOT with hard tabs. AUTO NUMBER (^K#) - VDE can automatically number items in a list. Just type a "#" character where each number in sequence should go, for example: #. First item. #. Second item... You can then mark the list off as a block (see BLOCK COMMANDS), and use the ^K# command: VDE will insert the numbers (1, 2, etc) in place of the "#" markers. You will be asked for the starting number; the default is of course 1. (Once this is done the markers are gone. For frequently revised lists, leave the "#" markers in the file on disk; use ^K# just before printing, and do not save afterward.) If auto format (^OM) is on, text will be realigned to compensate for varying length numbers. AUTO SAVE (^KA) - When on, VDE saves any changes you have made to disk automatically, at regular intervals. This ensures that you don't lose too much work if you make a mistake, have a power outage, etc. ^KA lets you set the interval (1 to 255 minutes), or turn this feature off entirely (0). Just press [Enter] to restore the default, normally 0. [This can be changed with VINST.] Notes: Auto save does not actually occur during intervals when the keyboard is not in use, or while you are editing another file. It cannot save untitled files. BLOCK COMMANDS (^KB,^KK,^KH,^KZ,^KY,^KC,^KV,^KW; ^QB,^QK; ^KPB) - A BLOCK of text is delimited by two markers, set by ^KB (beginning) and ^KK (end), which remain in place until reset elsewhere or deleted. Alternatively, you can mark a block by moving the cursor to the start or end, holding down the Shift key, and using the PC arrow keys, [Home, End], or [PgUp,Dn] to move the cursor to the other end of the block, releasing the Shift key when finished. ^KH unmarks the block, removing any marker(s). The block operation commands all require a block to be marked first: ^KY goes to and deletes the block (including markers). (If you want to return the cursor to its position before the deletion, type ^QP.) ^KV moves the block (including markers) to the present cursor location; ^KC simply copies it, leaving the original marked. Any place markers present are not transferred. (The cursor cannot be IN the block.) ^KZ "zooms into" a block: the rest of the text is hidden, and the block is temporarily treated as the entire file. This can simply isolate one portion of a file for your attention; it can also be done to limit the scope of many VDE commands (^QA, ^B, ^KI...) to that portion. Use ^KZ again to zoom back out. In zoom mode: pagination is off; you can use block operations, though any block markers within will disappear when zooming back to the whole file; if you save (^KS), VDE will automatically zoom back out of the block first. ^KW writes the block text to a disk file; you will be asked for the filename (and optional mode). Normally this will overwrite any existing file; however, you can choose instead to append the text at the end of the file, by typing a "+" before the filename: Write to file: GORT overwrites +GORT appends ^QB, from wherever you are in the file, moves the cursor to the block start; ^QK moves to the block end. ^KPB (^KP with B option) prints the block text only. (See PRINTING.) DELETING (^G,[Del],^T,^Y; ^QY,^Q[Del],^QT) - ^G deletes the character at the cursor. Normally, [Del] or ^[BkSp] deletes the one to the left, and [BkSp] (^H) moves left without deleting. [Instead, [BkSp] may be instal- led to delete to the left, and [Del] to delete at the cursor.] ^T deletes a word to the right (everything from the cursor to the next word break.) ^Y deletes the entire current line. ^QY deletes just the part of the line to the right of the cursor; ^Q[Del] deletes the part to the left. ^QT, followed by a character, deletes everything until the next occurrence of that character. EXAMPLE: ^QT. (period) deletes to the end of the sentence. Special case: ^QT^M ([Enter]) deletes to the next HARD CR, the end of the paragraph. Unintended deletions can be recovered (see UNDELETING). ENVELOPES (^KPA) - VDE provides an easy way to print a single envelope to accompany a letter, via the "A"ddress option of the print command: 1. Begin by moving the cursor to the address of the recipient, and marking this as a block (see BLOCK COMMANDS): {Chester Fludd 193 Lakota St "{}" = block markers Norman, OK 73069} 2. Then use the print command (^KP), and at the options prompt, type "A", followed by "1" or "2" to specify the envelope size: 1 for smaller (letter) size envelopes, approx. 3-5/8 x 6-1/2"; 2 for larger (business) size, 4-1/4 x 9-1/2". 3. Optionally, you may include a return address for the upper left corner of the envelope: enter this in "double quotes", using a backslash (\) to mark the beginning of a new line. Example: Options: A2"Your name\Your street\Your city" (You may find it convenient to set up envelope printing with your usual return address as a macro key, if you will use it often. See MACROS.) 4. Load the envelope correctly in your printer, and press [Enter] to print it. Then you can continue to edit or print the letter itself. NOTES: Different printers handle envelope feeding in various ways. VDE prints the address(es) in the appropriate format; you have to ensure that they wind up on the envelope. With some dot matrix or wheel printers, you can feed in a single envelope, and manual positioning on the platen may be sufficient. With other printers, a separate tray is available for envelopes, and you will need to install special codes to select the proper tray. Many laser printers expect to feed envelopes sideways, so you will need codes to print in a landscape font. [Any control codes needed to prepare your printer for an envelope can be added with VINST; see PRINTER INSTALLATION.] Because of the way laser printers operate in landscape mode, VDE ordinarily prints both size envelopes with their RIGHT edge in the same place. This means that on other printers, the LEFT edge of the smaller envelope must be placed 3" (30 columns) in from the left margin. If this is inconvenient, it can be overridden by specifying the left margin option (e.g. "L0") AFTER the "A1" option. FILES (^KL,^KR,^KJ,^KF) - ^KL loads new file(s) to edit, REPLACING the current one. (If the file has been modified, you will be prompted to confirm that you mean to abandon it; if you want to load file(s) in ADDITION to the current one, use AltL instead.) You can enter any number of filenames, with optional modes (see SYNTAX). ^KR reads in the contents of a single disk file, inserting the text at the current cursor position. ^KJ deletes any disk file you specify. (If you need more complex file utilities, remember that you can run any DOS command with AltR.) All these commands prompt for specific filenames. If you are unsure, or would rather see a directory first, you can call up the FILE BROWSER by pressing [Enter] alone for *.*, or typing a filename with wildcards, like *.LET. (Note: if you want to load an "untitled" file, press ^J or ^[Enter], instead of [Enter], at the ^KL prompt.) The file browser can also be called up directly with ^KF. You may specify a directory (or ".." for the parent directory) and/or filename mask, and the contents will be alphabetically listed. (The default, if you just press [Enter], is the directory shown, and all files *.*.) Files display alphabetically in uppercase, then directories in lowercase. If there are more items than will fit on screen, you will see "..." to indicate this; the display will scroll as needed. [Note: display of .COM, .EXE and other unreadable files can be suppressed.] To remove the display, press [Esc] or [Space]. But while it is on screen, you can move the cursor through the list with the arrow keys, [PgUp,Dn], or [Home,End]; additionally, a letter "A..Z" may be typed to go to the first file beginning with that letter. When the cursor is on the selected item, you can press: [Enter] to load this file in place of the current one (see ^KL); ^L to load it as an additional file (see AltL); ^R to read it into the current file (see ^KR); [Del] to delete this file (be careful; deletion is immediate). If the file you want to load/read requires a different file mode, you can first press "/" and the correct mode letter (A,U,N,C,W,5,P,X,M, or space). You may also select a directory, in which case you can press: [Enter] to view its contents in turn; [Del] to remove it (if empty). FIND/REPLACE (^QF,^QA; ^L) - ^QF is the command to FIND a string. The search normally proceeds from the cursor position forward, and is case (upper- lower) sensitive. The character ^_ (Ctrl-underline) functions as a wildcard: it will match any single character. The single code ^M (CR, or [Enter]) indicates a "newline" in VDE. Some control codes can be entered directly; some (like ^M) require the ^P prefix. Graphics characters can be entered using AltG. Examples: Find: ^MLABEL matches "LABEL" at start of line only; Find: p^_^_ce matches "piece", "peice", etc. ^QA is the REPLACE command. It asks for a string to find, as above, then what to change it to. Normally, the cursor will move to each occurrence of the string, and you will be asked ("Chg?") whether to change it; answer "Y"es or "N"o, or "*" to change all the rest without asking, or press [Esc] to quit. There are several options for find/replace: "B" = search Backward through the file; "U" = case insensitive search (ignore Upper/lower distinction); "G" = search Globally (from start or end of file); "A" = Align (reform) paragraphs again after each replacement; "N" = No query: replace all instances without asking. To skip the options prompt, finish entry of the find string (for ^QF) or replace string (for ^QA) by typing ^J or ^[Enter] instead of [Enter]. Notes: "A"lign is assumed by default if auto format (^OM) is on. (Be careful about mixed format files in this situation.) "N"o query is assumed whenever ^QA is used in a macro. ["U"ppercase can be set as your default, in which case pressing "U" means case sensitive.] There is no option for "whole word only" -- begin and end with a space to do this. ^L instantly repeats the last find or replace operation; the "B", "U", and "A" options remain as last specified. FOREIGN CHARACTERS - Characters in the upper ASCII range (128-255), such as the foreign letters and accents, can be entered directly into text using either standard DOS method: one of the DOS KEYBxx keyboard map utilities, or the [Alt] key and numeric keypad (with [NumLock] on, hold down [Alt] while pressing 1,5,5 for character 155). VDE treats these characters as "graphics": you are limited to a total of 32 such codes at a time, and any that you have used may be found in the menu brought up by the AltG command. See GRAPHICS. GRAPHICS (AltG) - You can enter an IBM graphic (or foreign) character into the file either directly from the keyboard, via [Alt] and the numeric keypad, or with the AltG command. You will be presented with a menu of up to 32 characters (labeled A-Z,1-6) to choose from; the default set contains some useful box drawing parts, and has room free for other characters that might be loaded. [It can also be modified with VINST.] Any open menu entry can be defined on the spot. Type "=", then the code (A-6) to change. You can then select the desired character from the complete graphics set, by moving the cursor to it and pressing [Enter]. Alternatively, if you press [Esc], you may enter the extended ASCII code in either hex (2 digits 80-FF) or decimal (3 digits 128-255) format. Example: the Greek alpha can be entered either as "E0" hex or "224" decimal. Once defined, the graphic can be entered into the file by pressing its menu letter; its definition cannot be changed again during the same editing session. NOTE: In addition to the 128 graphics characters, the code ^Z (hex 1A, decimal 026) may only be entered as a graphic. (^PZ embeds not ^Z but a place marker.) Furthermore, several codes in the range 00-1F,7F (000- 031,127) are reserved for internal use; though they can be entered with ^P, they will be represented as graphics. CAUTION: If you load a file containing many graphics (or binary data that will be interpreted as graphics), VDE will try to add each in turn to its table. If the graphics table fills up, any further graphics will be replaced by duplicates of graphic #6. You will see an error message, and the file will become "untitled", to guard against saving to disk and corrupting the file. If you frequently work with graphics characters you will want to keep your default table relatively empty to avoid this. Graphics are stored in disk files in accord with the current file mode. Printing of graphics depends on whether your printer font is installed [see PRINTER INSTALLATION] as IBM graphics (PC8) or Roman8, or neither, in which case VDE will "emulate" them, choosing standard ASCII character overstrikes that come as close as possible. This usually works well, especially for the foreign language characters. HEADER (^OQ) - The "header" at the top of the screen can be toggled on and off with ^OQ. [The default can be set either way.] It provides useful information, but can be removed if you prefer to edit with a screen showing nothing but your text. It looks like this: ----------------------------------------------------------------------- + VDE.DOC /A P 14 L 11 C 48 Ins vt hy AI DS J+ PS " ^K_ or (NP/BZ) (WIn) (AF) (MR) ----------------------------------------------------------------------- '+' = Multi-file flag. Present if other file(s) are being edited. 'VDE.DOC /A' = Current filename and mode. The full drive and path information, along with other files being edited, can be displayed with the ^KI command (see INFORMATION). 'P 14, etc' = Cursor position in file by page (in document modes), line, column. If pagination is off (^OP0), you will see 'NP' instead of a page number; in block zoom mode (^KZ) you will see 'BZ'. 'Ins','WIn' = Insert mode (^V) or Word Insert (^]) on. 'vt' = Variable Tab mode (^OV) on. 'hy' = Hyphenation (^OH) enabled. (Documents only) 'AI' = Auto Indent mode (^OA) on. 'AF' = Auto Format mode (^OM) on. (Documents only) 'DS' = Double spacing (^OS) on. 'J+/-' = Right Justification mode (^OJ) on. (Documents only) 'MR' = Margins released (^OX). (Documents only) 'PS' = Proportional spacing (^OK) on. " = Double quote mark appears during macro recording (Esc"). '^K_' = Command key prefixes (and some prompts) display here. HYPHENATION (^OH,^P-) - ^OH toggles hyphenation on and off. If off, midword hyphens are not treated as wordbreaks. [The default can be changed.] VDE can't hyphenate automatically, but it can recognize hyphens that you type in the text, treating them as a legitimate place to break a line. In addition to ordinary hyphens, "-", there are "soft hyphens" (SHs), which you can enter by typing ^P- (^P,hyphen), and which display in a different color. SHs indicate optional places to break a long word: they will print as a hyphen when they fall at the end of the line (that is, when actually in use to break a word), but do not print if they wind up in mid-line. (Note: only WordStar (/W or /5) file modes store soft hyphens as such; when saving to disk in other modes, as in printing, they either become hyphens or disappear, as appropriate.) INFORMATION (^KI,AltI) - ^KI displays an Information message telling you: The full name (including directory) of the current file; When it was last saved, and whether (Y/N) it has been changed since; Any print toggles (^B,D,S etc) that seem to be mispaired; A word count for document files (useful for professional writing); The current size of the file in bytes or K (1K = 1024 bytes); The number of bytes of memory used and free in this text segment; The amount (in K) of memory free to edit further files; The names of all other files being edited. The AltI command displays the VDE version, date, and copyright. (An uninstalled copy of VDE does this automatically on startup.) INSERTING (^V,[Ins],^],^_,^N) - ^V or [Ins] toggles Insert mode on/off, and ^] toggles Word Insert. When both are OFF, VDE is in overwrite mode: any text to the right of the cursor is replaced as you type. With Insert (^V) ON, any existing text is instead carried to the right. With Word Insert (^]) ON, you can type over the letters of a word, but anything you add at the end of the word (when the next character is a space) is inserted without overwriting; this is a handy feature for revising text. [The default insert status can be changed.] The ^_ and ^N commands (insert space, CR) are most useful in Overwrite mode (avoiding the need to turn Insert on and back off). JUSTIFICATION (^OJ) - ^OJ controls right justification mode, cycling between three states: ADD. ("J+" in header.) Text paragraphs will be formatted with an even right margin, by inserting extra spaces between words as necessary. REMOVE. ("J-" in header.) Formatting will undo justification by removing any extra spaces between words, leaving an uneven right margin again. OFF. Formatting does not change spacing of text; right margin is left uneven. Thus the Reform (^B) command can justify or de-justify text as desired. Right-justified text should not be saved to disk in file mode /U (which has no margin structure) or in modes /X, /M, or /P (because XyWrite, MS Word, and WordPerfect will not recognize VDE's method of justification). Justification does not work with proportional spacing (^OK). LINE SPACING (^OS) - ^OS toggles between single and double line spacing. In double space mode, the following functions generate double carriage returns: [Enter] (^M), Insert CR (^N), Reform (^B), Wordwrap. You can easily mix single and double spacing; ^B can convert between the two. Note: a single-spaced file can also be printed out double-spaced with the "D" option of the ^KP command (see PRINTING). MARGINS (^OR,^OL,^OX,^OC,^OF) - ^OR sets the Right margin, and enables text formatting. At the prompt, enter the column number (up to 255), or just press [Enter] for the current cursor column. (Note: in proportional mode (^OK), the number is interpreted in 1/10" instead of characters.) ^OL similarly sets the Left margin column; the value must be less than the right margin. (^OL is normally used for indenting selected paragraphs. To leave blank space at the left of the page throughout when PRINTING, see the "L" option of the ^KP command, or the left margin setting in PRINTER INSTALLATION.) "Wordwrap" is automatic in all document modes whenever the margins are set: anything typed before the left margin will move up to it; anything typed past the right margin will wrap over to the next line. (See also REFORMAT and AUTO FORMAT.) Wordwrap and formatting are disabled if the right margin is set to 1, or while margins are released (^OX). (NOTE: Margins cannot be set in /N (nondocument) mode; a left margin cannot be set in /X, /U, or /M mode.) ^OX toggles margin release, allowing you to type outside them. ^OC Centers the current line with respect to the margins; ^OF sets the line Flush right. The cursor advances to the next line. MATCHING FILES (AltM) - This command can locate small differences between two largely similar files (perhaps an earlier and a later revision of your work). You must first load these two files (AltL), then split the screen between them (AltW), and position the cursor in corresponding places in both files (for example, the top). Then press AltM. Starting from these positions, VDE searches for any difference between the files. If there is one, VDE will stop on those lines, showing the disagreeing passages side by side. If you want to continue, press AltM again. (If the difference was significant you may first need to reposition one cursor to match the other.) If the cursor winds up at the end of both files, they match. Note: in document modes, AltM compares word by word, ignoring mere formatting differences (margins, spacing etc). In /N mode, it is an exact character by character comparison. MOVING AROUND (Arrows; ^F,^A,^C,^R; ^QE,X,S,D; ^QR,C; ^QI,^QL,^QN,^QP; AltO) - VDE supports two sets of Arrow keys, which function interchangeably: the four arrow keys [^,v,<,>] on the IBM keyboard, and the WordStar "diamond" ^E,^X,^S,^D. These keys move the cursor one unit up, down, right, and left respectively. There are many other movement commands as well: ^F or ^[>] moves right, to the start of the next word; ^A or ^[<] moves left, to the start of the current (and then previous) word. ^C or [PgDn] scrolls forward (down) one screen; ^R or [PgUp] scrolls backward (up) one screen. Preceded by ^Q, any arrow key moves more Quickly: thus ^QE, ^QX go to the top or bottom of the screen; ^QS, ^QD to the left or right end of the line. Similarly, ^QR and ^QC scroll all the way to the beginning or end of the file, respectively. ^QI moves directly to a given page (for documents) or line (for non- documents). In documents, ^QL and ^QN move to the start of the Last or Next page, respectively. ^QP returns the cursor to its Previous position -- before the last large movement occurred. (This means AltM,AltO,^B,^QR,^QC,^QF,^QZ,^QB, ^QK, and any other command that moves to the block location via ^QB.) ^QP can be used again to cycle between these two positions in the file. AltO displays an Overview bar at the top of the screen. The length of the bar corresponds to the filesize, and the current position is marked so you can see where you are. You can move the place marker left or right with the arrow keys; the cursor remains in the original (current) position. To move to the selected position, press [Enter]; press [Esc] instead to cancel. MULTIPLE FILES (AltL,AltB,AltN,AltX,AltQ,AltC,AltP) - VDE allows you to edit up to 8 files simultaneously, if you have enough memory. This can be done from the command line, by giving a list of several filenames. Otherwise, to Load additional files, press AltL. You can enter any number of filenames, with optional modes (see SYNTAX); for an untitled file, press ^J or ^[Enter]. You can also access the file browser with [Enter] or wildcards (see FILES). (You will get an error message if you run out of memory, or are already editing the named file, or 8 files.) Once multiple files are in use, AltB and AltN can be used to cycle back and forth through the files being edited. If you Quit or Exit (^KQ,^KX) from one file, you will be returned to the previous one. For convenience, AltX exits ALL files immediately, saving any changes made. AltQ quits ALL files immediately, without saving; if any of them have been modified, you will be prompted (just once) to confirm this. AltC Cuts a marked block of text, placing it in a buffer for later recovery. (The original remains, unless you delete it with ^KY.) AltP Pastes in the previously cut text at the cursor position, allowing block copying and moving between files.) It is possible to view two files on screen at once (see WINDOWS). PAGE PREVIEW (^OD) - This command shows you a preview of the text as it would print: with all non-printing codes (markers, ^P codes, etc) hidden, and page breaks indicated by a row of dotted lines. This is handy for making sure that text is aligned properly, and will help you avoid wasting time and paper on unacceptable printouts. You can scroll through the file in this mode with [PgUp,Dn] or ^R,^C; or move to the top or bottom, with ^[Home,End]. Press [Esc] to continue editing. PAGINATION (^OP,^PL) - The ^OP command sets the page length. Enter a value 0 to 255 lines, or just press [Enter] to restore the default [normally 56]. When the value is nonzero, it determines the page and line shown in the document header ("P xx L xx"), and all page functions in the Print routine (pagination, headers, start/stop at page) are enabled. A formfeed will be sent to eject each page. [VDE does not send a formfeed before printing; install one in your printer initialization if you want.] When the value is zero, pagination is off. The header will say "NP L xxxx", showing you the absolute line number in the file; printing occurs with no page breaks. (This is useful for printing small things right after each other on the same sheet; or, in conjunction with the "*" option, multiple copies of index cards, labels, etc.) The ^PL command embeds a formfeed (^L) in the text, to begin a new page; the best place to put it is at the beginning or end of a line. PARAGRAPH INDENT (^OG) - Of course you can indent text simply by changing the left margin (^OL), but there are times when you want only a temporary indent. ^OG gives a "paragraph indent"; each time you use it, the left margin is reset to the next tab stop over (see TABS). The indentation lasts until you type the [Enter] at the end of the paragraph (or use the ^B or ^OL commands), at which time the original left margin is restored. PLACE MARKERS (^PZ,^QZ) - You can set any number of temporary place markers in the text with ^PZ (they display as a highlighted "Z"). The ^QZ command moves the cursor to the next place marker in the file, cycling back to the top of the file as needed. (Place markers are NOT saved to disk.) PRINT STYLES/CODES (^P) - This command prefix is used to enter various "codes" in the ASCII range 00-1F into the text, usually for purposes of printer control. Most codes are entered in a standard fashion: ^PA embeds ^A, etc. Those with defined functions in VDE documents display as highlighted letters ("A" etc); the rest (all, in non-documents) display as graphics. It is possible to embed the code ^Z (hex 1A) in a file, but only via AltG (see GRAPHICS), since ^PZ gives a place marker. (Use caution; many programs treat the actual ^Z code as an end of file mark.) Several other common control codes produce special effects: ^P^I - hard (ASCII) tab - printers respond variously to this ^L - formfeed - will cause a page break ^H - backspace - overstrike previous character ^M - carriage return - enter a CR without a LF to overstrike line (do NOT hit [Enter] again after this, just continue typing) The further codes below operate only in documents. ^P^G causes printing to pause, with "^PG" in the display, until you press [Enter] to continue. This allows you to adjust the platen for printing various forms. (Note: on many dot matrix printers, can only be used at the start of a line.) ^PEsc or ^P[ can be used to embed the "Escape" code (hex 1B) in a file if desired. But these are most commonly used for printer control, and VDE offers a much simpler way of doing this. In place of complex "escape sequences" for print styles (underlining, etc) in document files VDE lets you enter a single marker, which will be translated into the proper codes during printing. VDE supports a set of 13 codes for this purpose: seven toggles, six switches. [See PRINTER INSTALLATION on how to install the proper driver for your printer. Otherwise, only ^PS and ^PX will work.] The conventional WordStar meanings of these codes are: Toggles: ^P^B boldface Switches: ^P^Q (user def 1) ^D ("doublestrike") ^W (user 2) ^S underline ^E (user 3) ^Y italic ("ribbon") ^R (user 4) ^T superscript ^A alternate pitch ^V subscript ^N standard pitch ^X strikeout [has no installation] But you can use them for anything you like. "Toggles" are good for features like underlining that are turned on and off; enter them in pairs, to mark the beginning and end of the desired text. "Switches" are better for multi-valued parameters like character pitch; enter them once. If toggles are not properly paired, you will find print effects continuing throughout the rest of your document. To save time and effort, use the ^KI command to check for this before printing. (If an "S" appears under the "^Check" heading, there is an unpaired ^S somewhere.) PRINTER DRIVERS (AltV,AltU) - Since many people use more than one kind of printer, VDE accomodates two different printer drivers, a primary and an alternate. Before printing a file, you can select which one is active using AltV. [You can change both drivers with VINST.] AltU gives you access to an unlimited number of further printer drivers in the form of .VDP disk files; select "L"oad, then type the file name. [See PRINTER INSTALLATION for instructions on how to create such files.] The new driver will replace the previous primary. PRINTING (^KP) - The ^KP command Prints the file from memory. You will be asked for a set of "Options:", at which point you may enter one or more of the following, in any order: '...' sends a string of printer control commands before printing begins. These must be entered in ASCII format: type in the ACTUAL characters or control codes. If the command is "Esc A" (1B 41 hex), type "Esc","A". (For control codes, 01 = ^A, 02 = ^B, etc. Some will require the ^P prefix: 00 (^@) = ^P@, etc. You may find an ASCII table helpful; see PRINTER INSTALLATION.) Tnn sets a TOP MARGIN skip of nn lines. [The default margins can Lnn sets a LEFT MARGIN skip of nn columns. be set with VINST.] D DOUBLESPACES the printout. ^ FILTERS control codes (like ^X) so they print out as text "^X". *nn prints the entire job out nn TIMES (nn=1...255). B prints only the currently marked BLOCK. (FILENAME) redirects printer output to a disk file. All print control codes will go into the file just as they would have been sent to your printer. If you want to append the output to an existing file, type a "+" before the name: (+FILENAME). A ADDRESSES an envelope; see ENVELOPES. N NUMBERS pages sequentially, at top right. C numbers pages at bottom CENTER. "..." uses the quoted string as a HEADER. The string will print at the top right unless it begins with a "<" character, in which case it prints at the left. Note: you can include the current Filename, Time or Date in the header simply by entering ^F, ^T, or ^D, respectively. S SUPPRESSES the header/page number on the first page of output. F prints FACING pages (header/number reversed on even pages). O,E prints only Odd or Even pages (print one, then run the paper back through and print the other, for double-sided printing). P PAUSES for your keystroke before each page prints (sheet feed). @nn begins printing AT page nn of the document. #nn prints only (up to) a TOTAL of nn pages. =nn RENUMBERS the printout to start at page nn. (The paging options (T,N/C,"...",S,F,O/E,P,@,#,=) will NOT work if the page length is set to 0 (^OP), or if 'B'lock print was chosen. 'C' cannot be used together with 'N'.) EXAMPLE 1: Options: "<STATUS REPORT: ^D" N F will put a header like "STATUS REPORT: 10/19/90" at the top left of each page, and the page number at the top right (vice versa on even pages). EXAMPLE 2: Options: L12 #1 will print one page only, with an added left margin of 12. (Printing a single page is a good check of page layout before going ahead to print a long file. To continue at page two, of course, use Options: @2.) EXAMPLE 3: Options: BD(+SCRATCH) will append the print output of the current marked Block, double spaced, to the disk file SCRATCH. NOTES: The left margin setting (via "Lnn" or VINST) is in columns, and its physical width will vary according to the font in use. If you need a fixed margin, it is better to find your printer's Esc command for a left margin setting in inches or dot columns, and add this to your printer initialization string. If you are in /W or /5 file mode, any WordStar dot commands in the file (lines beginning with ".") will not be printed. You can abort printing at any time by pressing [Esc]. PROPORTIONAL SPACING (^OK) - Normally VDE assumes a fixed pitch font: one character equals one print column. Yet if your printer has a proportional font, you can get VDE to use it, and to format text so that it will print with more appropriate margins. With ^OK on, your printer will be put in proportional mode when printing (^KP); and all wordwrap and reformatting (^B,^OC,^OF) will take advantage of a table of varying character widths, resulting in a better aligned printout. In proportional mode, the right margin needs to be interpreted in inches rather than characters, based on a conversion of 10 cpi, so that a right margin (^OR) of 70 means 7.0". (Note: characters may well extend beyond the 70th column.) [See PRINTER INSTALLATION to install codes for proportional mode on your printer, and CHARACTER WIDTHS to adjust the width table.] REFORMAT ([Enter],^B;^OB) - In documents, pressing [Enter] creates a permanent or "hard" Carriage Return marking the end of a paragraph. (This is a CR without a preceding space; wordwrap creates a removable "soft CR", preceded by a space. See TEXT FORMATTING.) ^B reformats the paragraph the cursor is in according to the current margin settings and line spacing. (Thus ^B is used not only to reshape a paragraph after editing, but also to change its format in various ways: see MARGINS, JUSTIFICATION, LINE SPACING.) If the top line is indented relative to the next one, VDE preserves that as paragraph indentation. To reformat an entire file use the MACRO command (Esc[) to repeat ^B. (See also AUTO FORMAT.) ^OB toggles display of hard CRs, which are normally marked by a left- arrow character in document files, to distinguish them from soft ones. If you find this distracting, it can be turned off. RULER LINE (^OT) - To help you align text properly, ^OT displays a "ruler line" above the text. Type ^OT again to remove it. A moving pointer indicates the current column. In each column you will see one of several symbols: the arrow "v" is the cursor column; "L,R" designate the current margins; "." indicates areas outside the current margins, "-" within them. Also, tab stops are marked by either "!" (Variable) or ":" (Hard). Examples: (/A mode) L-----!---!----------v--!--------------R........ (/N mode) :.......:.......:....v..:.......:.......:....... RUN COMMAND/SHELL (AltR) - AltR lets you run DOS commands without leaving VDE. An imitation DOS prompt is produced (e.g., "C:\WORK>"); you can copy or rename files, or run any other program you like, and afterwards VDE will prompt you to "Press [Esc]", which will return you to your undis- turbed VDE editing session. In addition, you may type "SHELL", which lets you out into what is known as a Command Shell: you are actually back IN DOS, and can use any number of commands or move around as you like; when through, you need to type the DOS command EXIT to return to VDE. Caution: don't load new memory-resident utilities from within the AltR command; this fouls up the DOS memory allocation. To use AltR, you must have enough free memory to load and run the chosen program; and VDE must be able to find COMMAND.COM in order to execute it, via the COMSPEC environment variable. Be sure either that your AUTOEXEC.BAT file includes a line like SET COMSPEC=C:\COMMAND.COM or that your CONFIG.SYS file includes a line like SHELL=C:\COMMAND.COM C:\ /P (In either case replace "C:\" with the appropriate directory.) SAVE/EXIT (^KE,^KS,^KX,^KD,^KQ) - ^KE renames your work, allowing you to change to a new filename (and/or new directory or file mode) before saving. If you enter a new directory or file mode alone, that change will be made, while the filename remains the same. (Note: If you want to make your work "untitled", press ^J or ^[Enter], instead of [Enter], at the prompt.) ^KS saves your work so far, writing the file to disk under the filename in the header. (If it's "untitled", a new name will be requested.) If the file has not been modified, you will be prompted to confirm that you meant to save it again anyway. For safety, a copy of the existing file is preserved as a BACKUP FILE (with extension ".BAK") each time you save changes. [If you prefer not to use BAK files, you can suppress their use with VINST.] There are several different commands for finishing up: ^KX saves your work (if modified), and then EXITS to DOS. ^KD saves your work, then loads a new file to edit. ^KQ just QUITS, without saving to disk. If the file has been modified, you will be prompted to confirm that you meant to do this! SCREEN CONTROLS (^W,^Z; Esc[^,v,<,>]; ^OE,^OZ) - VDE provides a number of commands to control the display screen: ^W and ^Z scroll the screen up and down a line at a time, without moving the cursor in the text (unless necessary). Preceded by [Esc], any arrow key also causes the screen to scroll: up/down by 1/4 screen, or right/left 32 columns. Again, the cursor is not moved unless necessary. (The screen cannot shift rightward past the end of the current line.) ^OE makes the current line the top of the screen. ^OZ temporarily blanks the entire screen; good for avoiding CRT burn- in, or just protecting work from prying eyes or fingers. Restore the screen by pressing [Esc]. This is also useful if some other software (like a resident utility) has messed up the screen: type ^OZ,Esc and VDE will completely restore it. SCREEN SIZE (AltA,AltE) - On IBM compatible systems, VDE automatically adapts to any size text screen currently in use (minimum: 40 columns, 8 lines). This means that (1) VDE will run on laptop/palmtop computers with small displays, and (2) visually impaired users can use the DOS command MODE CO40 to edit with a 40 column large-type screen. When running with fewer than 80 columns, VDE omits toggle indicators from the header; also, some menus remain in 80-column format, and can be scrolled horizontally by pressing the right and left arrow keys while they are on screen. On IBM EGA/VGA video systems, you can use your own software (like the popular UltraVision program, or any utilities that may have come with your video adapter card) to change the font or screen size (lines,columns) before running VDE, or even while editing (via the AltR command). VDE also offers two internal commands to vary screen size: AltA changes the screen width, toggling between normal (80-column) mode and wide (132-column) mode. It can be used alone, or in combination with AltE. This command works ONLY with certain brands of video cards which offer 132 column displays [see INSTALLATION to specify yours], or if you are running UltraVision with a card that supports its 132 column mode. AltE changes the screen length, varying the number of text lines displayed. In its most basic form it simply toggles between normal 25- line mode and a compressed mode of 43 (EGA) or 50 (VGA) lines. But when possible (with VDEOPT.DAT present or under UltraVision), it displays a prompt offering a wider range of sizes: with VDEOPT.DAT VGA - 20,25,28,33,40,50,57 lines EGA - 17,25,29,35,43,50 lines with UltraVision VGA - 25,36,50,60/63 lines EGA - 25,34,43,60 lines You can enter a letter code A-G, or [Enter] for your default value [which can be changed with VINST]. Larger text is easy on the eyes; smaller text can pack a whole page of text into one screen. To make this range of sizes available (without UltraVision), the VDEOPT.DAT file must be in the current or VDE directory (set with the SET command -- see DIRECTORIES). SPLITTING FILES (AltS) - If you encounter a text file that is too large for VDE to load and edit, you can divide it into manageable chunks with the Split command. You will be prompted for the name of the file to split; VDE will divide it in pieces whose names have a number added at the end of the file name. Example: BIG.DOC will split into BIG1.DOC, BIG2.DOC, etc, each of which you can edit separately. After 9, the numbers continue with letters A..Z. (The original file also remains on disk.) If necessary, the files can later be reassembled into one with the DOS COPY command, for example: COPY BIG1.DOC+BIG2.DOC BIG.DOC. TABS ([Tab],Shft[Tab]; ^OV,^OI,^ON; ^PI,Esc[Tab]) - There are two Tab modes, Variable and Hard; ^OV toggles between them. In Hard Tab mode the Tab key produces an actual ^I (ASCII TAB) character. Hard Tabs display at fixed intervals [normally 8 columns; optionally 4 or 16]. In Variable Tab mode (the default for documents), the Tab key moves to the next tab stop set. The cursor moves over any existing text; spaces are added at the end of a line if needed. Up to eight tab stops may be set with ^OI, or cleared with ^ON; the defaults are in columns 6, 15, 35, and 55. [These can be changed.] Both commands prompt for a column number, or you can press [Enter] for the cursor column. The Set command ^OI also accepts two options, both of which replace all previous tab settings: @nn Set tabs every "nn" columns #n1,n2,... Set tabs to columns "n1,n2,..." You can simply clear all variable tabs by typing "@" or "#" alone. The Shft[Tab] command tabs backwards (left to the previous stop), useful for moving around in tables, etc. You can always get a Hard Tab with ^PI, or a Variable Tab with Esc[Tab], no matter which tab mode you are in. TIME/DATE (AltT,AltD) - VDE can read the DOS system clock and insert the current time and date in your file automatically. Just press AltT for the Time, or AltD for the Date. The string will appear at the current cursor location, as though you had typed it in yourself: for example, 1:21 PM [or 13:21 -- VINST selects the format] January 15, 1988 [or 1/15/88, 15 January 1988, 15.1.88] UNDELETING (^U) - The undelete function can be used to recover accidentally deleted text or overstruck characters. The lost text will be replaced at the current cursor location. ^U may be used repeatedly to undo a sequence of deletions, recovering each character, word, or line in order. (Once all deleted text is restored, ^U does nothing.) Exception: block deletions cannot be recovered sequentially, they must be undeleted immediately (before any other deletion occurs). Undeletion can also be used as a sort of quick-and-dirty block move. For example, if the cursor is at the start of a word, the commands ^T^F^U (which of course can be assigned to a macro key) will swap that word with the one following it. Similarly, ^Y^X^U will swap two lines. UPPER/LOWER CASE (^^; ^K",^K',^K^) - ^^ (Ctrl-caret or 6) reverses the case of the character at the cursor, if it was a letter, and moves to the next. The ^K^ (^K-caret) command reverses all text in a marked block (see BLOCK COMMANDS); ^K" makes all text in the block uppercase, ^K' lowercase. WINDOWS (^OW; AltW,AltF; ^[PgUp,PgDn]) - VDE can split the screen into two windows, showing either two parts of the same file or two different files. In either case, AltF moves the cursor back and forth between the two windows. ^[PgUp] and ^[PgDn] scroll BOTH windows in synchronization. ^OW is used in a SINGLE file; it creates a window in the bottom half of the screen, duplicating the current file text. You can move to a different place in the file within this window, and continue editing, with the original text still in view in the top window. (Note: any modifications made to the file will not be reflected in the inactive window until you return to it.) Type ^OW again to undo windowing. AltW splits the screen Window between two DIFFERENT files being edited, showing you both at once. Type AltW again to undo. ================================ 4. MACROS ================================= FUNCTION KEYS ([F1]...[F12]) - Up to 48 macros can be assigned to function keys; they can then be recalled and used with one keystroke. Each IBM function key can be used alone or with Shift, Ctrl, or Alt, to produce: [F1]...[F10] = F01...F10 in VDE notation Shift-[F1]...[F10] = F11...F20 Ctrl-[F1]...[F10] = F21...F30 Alt-[F1]...[F10] = F31...F40 And, if you have an Enhanced (101-key) AT keyboard, also: [F11],[F12] = F41,F42 Ctrl-[F11],[F12] = F45,F46 Shift-[F11],[F12] = F43,F44 Alt-[F11],[F12] = F47,F48 VDE comes with [F1] set as a "Help" key (^J), but this can be changed. Otherwise, function keys are defined (with the Esc[ or Esc] command, or with VINST) and used exactly like macro keys. See MACRO KEYS. KEY DEFINITION FILES (AltU) - These files save sets of macro key or function key definitions, and should be given file types of ".VDK" and ".VDF", respectively. You can load any key file, along with your text file(s) to edit, from the command line (see SYNTAX). AltU can be used while editing: it will ask whether you want to "L"oad or "S"ave such a file, then prompt for the name of the file. The filetype MUST be ".VDK" or ".VDF", and will determine whether MACRO or FUNCTION keys are affected. If you load such a file, those definitions will replace any previous ones. If you save, the current definitions will be written to the file. [Key files can also be created or installed as defaults in your copy of VDE, using VINST.] MACRO DEFINITION AND USE (Esc[,Esc]) - To DEFINE a macro, type Esc[. You will be asked for the macro definition; then, whether to Use or Store it. (On storing, see MACRO and FUNCTION KEYS.) You may want to plan the macro first with pen and paper. If you Use the macro, you need to decide whether you want it to repeat (and if so how many times), and whether you want to watch it happen or not. VDE asks "Make Quiet, No-repeat, Both?" Reply "Q" for Quiet (fast) operation, or press [Enter] for visible (slower) execution. (The "N" option is intended for storing keys, but can also be typed here to skip the next question.) VDE asks "Repeat count?" Type the number of times to execute (0-254), or just [Enter] for 1; or "*" to repeat indefinitely. Normally, you can see the results as the macro executes, and you can abort it at any time by pressing [Esc]. If you choose to speed up macro execution by specifying "Q"uiet mode, only the header will be updated as the macro runs. (Don't do this if the macro concludes by requesting user input -- the necessary prompts would not display!) Macros will stop if an error occurs; the error message will be visible, and can be cleared by pressing Esc. Many commands (like Find or Reformat) are designed to generate errors at the end of the file so that an indefinite ("*") macro containing them will halt there. Other indef- inite macros may need to be aborted manually. (Exception: Esc$ can change error handling. See MACRO PROGRAMMING.) Once defined, a macro can be re-used with the Esc] command, which again gives you the options to Use or Store the previously defined macro. EXAMPLES: Note -- for clarity, macro examples will be given here as they function, not as they are typed in; remember that you will need to add ^P prefixes for certain control keys ([BkSp] (^H), [Enter] (^M), ^J, ^X, ^U, ^P). Keystrokes are often separated by spaces for clarity; the "_" symbol is used to represent an actual space character typed. 1. Reformat an entire file: after Esc[, just enter ^B Specify Quiet and indefinite repeat as options ("Q,*"). 2. View a file by scrolling slowly through it: Esc; ^Z (or ^C) This pauses, then scrolls down. (Again, repeat with "*".) 3. Macros are quite powerful. Can you figure out what this one does, if entered with indefinite repeat "*"? ^QR ^QF(^J ^G ^KB ^QF)^J ^G ^KK ^QC [Enter] ^KV (It takes all phrases in parentheses out of a file, making a list of them at the end of the file.) TECHNICAL NOTE: Ordinarily macros are completely self-contained, and NEVER request input from the keyboard while executing. There is one exception: using AltR to run a program from a macro is tricky. Input while in the program or shell must be typed by you. (VDE resumes control only when the program ends.) MACRO KEYS (Esc0...Z) - Both the Esc[ and Esc] commands also give the option of Storing the macro definition to a key. Up to 36 of these can be stored on keys 0...9,A...Z; they can then be called up with two key-strokes. (48 more can be stored on IBM function keys; see FUNCTION KEYS.) Example: if stored to key 3, a macro can be reused simply by typing Esc3. VDE asks "Make Quiet, No-repeat, Both?" Reply "Q" for a key that executes in Quiet (fast) mode; "N" for a key that runs once, without asking for a repeat count; or "B" for both of these. Press [Enter] instead for a key that executes just like the "use macro" option, visibly, asking for a repeat count first. VDE asks "Store to key?" Press the desired key: a number 0...9 or letter A...Z for a Macro key (Esc0...Z), or a Function key like [F3], Alt[F9], etc. Again, don't choose "Q"uiet for a key that will request input from you. There is a total of about 974 bytes available for all 36 keys, and a 128 byte limit for any one key. (VDE's own input line is of limited width, but VINST can handle up to the full 128.) Trying to use an undefined key results in an error. You can delete a key definition by entering an empty macro string (Esc[, [Enter]) and storing it to the key. Keys defined with Esc[ or ] last only during the current editing session (VDE.COM itself is not modified). [VINST lets you install definitions permanently; see DEFAULT MACRO KEYS.] EXAMPLES: Keys are useful for storing a frequently repeated phrase; "EscW" is much more convenient than "World Wide Widgets Ltd. (N.A.)". You might also use several for sets of margins, like: ^OL 5 [Enter] ^OR 60 [Enter]. A key defined as ^QR ^N AltD ^OF would place the current date at the top right of a letter. Many VDE users set up a macro key to produce a personalized letterhead: for example, the macro ^N John Doe ^OC ^N 123 Main St ^OC ^N City, State ^OC will insert that three-line address, neatly centered. You can add print effects (bold, italic) to suit your taste. For a solid line separating this from the body of the letter, try adding ^N ^PS ^OF ^E ^V ^PS ^V ^X Macro keys can be used to create powerful new commands, for example: ^D ^A ^KB ^F ^KK will mark the current word as a block. And, similarly, ^QS ^KB ^X ^KK will mark the current line as a block. Macro keys can also effectively change the way VDE commands behave. For example, the Cut (AltC) command does not remove the cut text from the file; but if you wish it did, you can set up a command that does: just define EscC as a macro key consisting of AltC, ^KY. MACRO PROGRAMMING (^F Esc; Esc0..Z Esc! Esc=,~ Esc$ Esc() Esc+,- Esc&) - VDE has several commands that operate only within a macro definition, and give you conditional control over the execution of a macro, allowing real programming. ^F, entered as part of an input string, will be replaced by the current filename when the macro executes. This can be useful to refer to the current file when running compilers and file utilities. Thus, if you define the macro AltR compile ^PF /g /r1 [Enter], the ^F embedded in the string will be expanded, so that the DOS command executed by AltR will actually be something like compile C:\PGM\MYPROG.C /g /r1. Esc; (Esc-semicolon) gives a brief pause before macro execution continues, presumably so the user can see what's happening on screen. Use two or more to get a longer pause. Esc0...Z, when placed IN a macro, function simply as local "labels" 0...Z. They have no effect, but can be "jumped" to by other commands. Esc! followed by 0...Z is a "jump" instruction, causing macro execution to resume with the command following that label. Example: Esc!2 jumps to label 2. As two special cases, Esc![ jumps to the beginning of the macro, and Esc!] jumps to the end (exits). Esc= and Esc~ perform tests on the character at the current cursor position. There are two ways to use them: (1) Followed by a character, then a label 0...Z (or "[","]" for start or end), they are conditional jumps: they jump IF the character does (or for "~", does NOT) match the one specified. Example: Esc~^M2 jumps to label 2 if the current character is NOT a CR. (2) Followed by a character, then ">" or "<", they are search loops. They will continue to move the cursor right (or for "<", left) as long as the character at the cursor does (or for "~", doesn't) match, or until the beginning or end of the file. Example: Esc=_> moves right as long as the current character is a space (so it stops on a NONspace). If you program an endless loop, you will at some point have to abort by pressing Esc. Normally, a macro aborts when an error occurs. With Esc$ you can instead specify a label where execution should continue. Thus, after the command Esc$E, any command resulting in an error (like "not found") will cause a jump to label E, ignoring the error. Several commands allow the use of a counter variable. Esc() sets the value: for example, Esc(0) initializes it to zero. The Esc+ command simply increments the value; Esc-(minus) decrements the value, then jumps if it is zero to a specified label. (In addition to a number, you may use "[" or "]" for the start or end, or "@" to avoid jumping entirely.) Example: Esc-] decrements the counter, jumping to the end (exiting) if it reaches zero; Esc+@ simply increments it. Esc&, followed by 0...Z, is used to "chain" to another macro key. In this way you can build up strings longer than the 128-byte limit on any one key. This is a "jump", not a "call"; there is no returning. Example: Esc&M causes key M to execute. (You cannot chain to function keys.) Don't make macro programs Quiet until you're sure they work. EXAMPLES: 1. Here is a good macro program (best stored as a Quiet key) to move the cursor to the start of the current sentence: Esc~.1 ^S Esc1 Esc~.< ^D Esc=_2 Esc=^M2 ^S^S Esc!1 Esc2 ^D Esc=_2 Esc=^M2 You could explain this in programmer's pseudo-code as: If not "." goto label1 ;move left if already on period Move left label1: While not "." move left ;move left to previous period Move right ;move right to following character If " " or ^M goto label2 Move left twice ;skip over a period if it's not Goto label1 ; followed by a space or return label2: Move right ;okay, now move right as long If " " or ^M goto label2 ; as you see a space or return (all done) 2. A macro to move to the start of the current paragraph: ^QS ^S^S Esc=_[ ^D^D 3. If you have some text that you can't reformat because every line ends in HARD CRs, here is a macro that will "soften up" one paragraph's worth, leaving just one HARD CR at the end: ^QS ^X Esc=_] Esc=^M] ^S ^V_^V ^D Esc![ 4. A macro to match parentheses. Many programming languages use nested sets of parentheses, for example "{}" in C. This program, when the cursor is placed on an open bracket "{", will move ahead to find the closed bracket "}" that matches it: Esc~{] Esc(0) Esc1 Esc~{2 Esc+ Esc!3 Esc2 Esc~}3 Esc-] Esc3 ^D Esc!1 TOGGLE CONTROL (Esc*) - "Toggle" commands can create difficulties when used in macro and function keys: ^V, for example, toggles insert mode. But when you plan a macro key, you don't necessarily know how Insert will be set when the key is used! So if you use ^V in the macro, you don't know whether you just turned it off or on; you might be overstriking or inserting, and can't tell. The Esc* command provides a solution, by letting you specify exactly what state you want for each toggle. Esc* must be followed by a LETTER to identify a toggle, UPPERcase to turn it ON or LOWERcase to turn it off. (Insert and Justify each have a third state, as well.) For example, Esc*i will set INSERT OFF, regardless of its previous state. The toggles are: Autoindent (^OA) 'a'=off 'A'=on Doublespace (^OS) 'd'=off 'D'=on auto Format (^OM) 'f'=off 'F'=on Hyphenation (^OH) 'h'=off 'H'=on Insert (^V) 'i'=off 'I'=on 'W'=word Justification (^OJ) 'j'=off 'J'=on 'R'=remove Proportional (^OK) 'p'=off 'P'=on Varitab (^OV) 'v'=off 'V'=on Once you've used one of these you can revert to the usual commands (like ^V), if you prefer, because you WILL now know the toggle setting. NOTE: Previous versions of VDE handled this problem for Insert mode (alone) by turning insert OFF automatically before running any macro. This is no longer the case. RECORDING MACROS (Esc") - As an alternative to composing macros and using the Esc[ command to type them in, you can simply record a macro as you go about a task. Press Esc" to activate recording; type away; then press Esc" again to conclude. You will then be asked whether to use or store it, etc (see MACROS). No confusing ^P prefixes are needed, and you can take advantage of the full 128-key macro length. While recording, a quote mark (") will be visible in the upper right (prefix) area of the header, if the header is displayed. Note: Function and macro key commands themselves will not work while macro recording is in progress. ====================================[end]=====================================
