RBcomm v3.21 Copyright (c) 1989, 1990 Ralf Brown You may redistribute this program provided that you provide unmodified copies of all files, and do not charge any fee for making the copy. RBcomm is a lean and mean comm program which will run in 41K without file transfer capability or 65K with file transfer and shell-to-DOS capability. Since it is so lean, you will not get a lot of the fancy features of other comm programs, though there are plenty of features to let you get your work done (I've been using it exclusively for over two years, and have added features as I've found that I could be more productive with them than without). Features: small (runs in as little as 41K [65K with DSZ, 66K with Puma]) DESQview-aware pop-up menus seamless file transfer using DSZ, PCZ, or Puma Zmodem and Puma autodownload (others easily added) shell to DOS, using less than 1K while shelled keyboard reassignment, powerful keystroke macros 20-number dialing directory ANSI/VT102, VT52, and AVATAR level 0 terminal emulations 132-column support supports the 16550A FIFOs Registration: Continued use of DSZ requires registration with Omen Technology, Inc. See the DSZ documentation for details. If you like RBcomm, send me a picture postcard of some sight in your area. If you don't like RBcomm, feel free to send me a postcard anyway, telling me what you don't like. Support: none (after all, I'm not getting any money for this). I will try to fix bugs as time allows. DISCLAIMER: This software is distributed AS IS. The author disclaims all responsibility for any damages which might be incurred as the result of using the program.

To do so, copy the RBcomm files to the directory in which you wish to install them, change to that directory, and type RBCONFIG COMM.COM (if COMM.COM is not in the current directory, use the full path, i.e. C:\COMM\COMM.COM, or RBCONFIG will not be able to find it) Please do not use your original copy. If you forget to run RBCONFIG, you will be told to do so when you attempt to run COMM.COM. You will now be asked (via a menu) to fill in several groups of information. Press 'D' to set the directories and extensions to use. RBcomm dir: where the keyboard macro files and dialing directory are stored Swap directory: where to store the swap file when running DSZ or COMMAND.COM a RAMdisk is ideal for storing the swap file Macro file extension: default extension to apply to keyboard macro files Default macro file: keyboard macro file to load on startup and hangup if this file does not exist, RBcomm will use a built-in set of default key bindings Press 'S' to select the serial port to use. You may setup configurations for "COM1" through "COM4", as well as the default port to use when not otherwise indicated in the dialing directory. The values given for "COM3" and "COM4" need not bear any relationship to the numbering of the actual serial ports in your system (you could, for example, set them up to be the same as "COM1" except for the length of the break signal). RBCOMM does check that "COM1" and "COM2" exist according to the BIOS data area, however, to avoid running in a DESQview window which has incorrect settings for supporting serial communications. You may specify a separate setup string for each port. The setup string needs to ensure that the modem echos back any commands it is sent, and asserts carrier detect only while actually connected with another modem (for Hayes-compatible "AT" command sets, "E1&C1") Press 'M' to define the modem setup. In this section, you need to enter several strings to be sent to the modem. Note that you may enter a ^M (carriage return) by pressing Alt-M (hold down the Alt key and press M), an Esc by pressing Alt-E, and a control-H by pressing Alt-H, and a DEL (ASCII 127) by pressing Alt-D. Press 'R' to define the modem's responses. These should be the minimum substring that uniquely identifies the response. Press 'P' to setup dialing parameters. You may specify the name of the dialing directory, how long to try before declaring a time-out, how long to wait before trying again, and the break length. Break length specifies the length of the signal that is sent when you give the break command (default Alt-B) in multiples of the standard clock tick of 55ms. Press 'Z' to set the parameters for Zmodem transfers. There are three sets of parameters for sending files with Zmodem, allowing you to tailor the best throughput under up to three separate sets of conditions. I use the "fast" set for BBSs, and the "medium" set for my Unix account. The "slow" set is configured by default for a system which can't handle full streaming. Note that PCZ will work just fine in place of DSZ if you set the program pathname to PCZ instead of DSZ, and provide sufficient memory (PCZ needs more memory than DSZ). The general DSZ parameters (second item on submenu) allow replacable parameters introduced by a percent sign. See the EXEC macro command for details. The replacable parameters are expanded each time DSZ is invoked. Note that the default "portx" will cause DSZ to report the port as COM9, but it will still use the correct serial port. Press 'C' to set the colors you want RBcomm to use. You may select the default and "underlined" colors, as well as the colors to use on menus. Press 'V' to determine whether 132-column mode should be enabled, whether to start in 132- or 80-column mode, and the register values needed to set 132- column mode. When running under DESQview, RBcomm can tell DESQview to set the virtual screen size to 132 columns if you specify zero for AX. Press 'T' to adjust a number of toggles. "Local echo" allows you to turn on half-duplex operation by default. "Verbose" sets whether to include terminal control sequences in a log file. Visual bell specifies whether to flash the screen or sound a beep when a ^G is received (internally-generated beeps always use sound). "Check for enhanced keyboard" determines whether RBcomm will use the enhanced keyboard BIOS calls if it thinks those calls exist. Some systems incorrectly indicate support for those calls. Set this to 'N' if RBcomm appears to hang your system. "Allow RBcomm to change NumLock" determines whether RBcomm will change the state of the NumLock key when it receives the "keypad numeric mode" or "keypad application mode" commands. Disabling the NumLock changes is useful for laptop users without a separate number pad. "Should backspace send delete" specifies whether the values sent by backspace and control-backspace should be exchanged. Finally, press 'O' for miscellaneous options. "Time between sends in idle mode" determines how often Idle mode (see Alt-I) sends some characters to keep the connection alive. "Answerback message" allows you to specify the string which RBcomm will send when it receives a ^E. On choosing "Quit" from the menu, you will be asked whether to save the new configuration to disk. If you specify that you want to save the changes, the executable on disk will be updated. --------------------- DESQview Installation --------------------- After performing the file copy and configuration described in the previous section, you need to install RBcomm on the DESQview Open Window menu. In DESQview, tap the Alt key to bring up the DESQview menu, then press "O" for the Open Window menu, and "AP" to add a program. Select "Other", then fill in the directory in which you've placed the RBcomm files and press Enter. You will be given the choice of RBcomm, RBcomm plus DSZ, and RBcomm 132col; select one or more and press Enter. Now use "CP" from the Open Window menu to change the paths and/or the keys for starting RBcomm. The only difference between "RBcomm" and "RBcomm + DSZ" is that the former allocates the minimum amount of memory for RBcomm to run (41K), which is not enough to invoke DSZ, but does save 25K when you do not need file transfer capability. If your environment is particularly large, you may need to use Change a Program to increase the window sizes by a K or two. With certain screen sizes, you may also need to give RBcomm 1K of system memory (on the advanced options screen). "RBcomm 132col" and "RBcomm + DSZ" are the same except that the former defines the maximum screen size to be 20 columns (this is not a mistake, it reduces the DESQview overhead) and gives RBcomm sufficient system memory to store the 132x25 screen (be sure to tell RBCONFIG to allow 132-column mode!). If you are not interested in the reason, skip the rest of this paragraph. DV normally reuses the same section of memory when resizing the virtual screen. However, resizing it beyond the maximum defined by the .DVP (and "Change a Program" only allows 127 columns) causes an entire new buffer to be allocated. Thus, minimizing the "maximum screen size" also minimizes the DESQview overhead by reducing the size of the screen buffer which gets discarded. RBcomm is sufficiently DESQview-aware to ask DV for the size of the screen. If you want a 120x60 screen, just set the maximum window size to 120 columns and 60 rows. DESQview will display as much as it can on your screen, but RBcomm will use the full size. If you have enabled 132-column mode with RBCONFIG, RBcomm will also switch to 132 columns by the given number of rows when it receives the sequence "<Esc>[?3h". RBcomm refuses to load itself twice on the same serial port when running under DESQview. However, when shelled to DOS, you can load another copy in a different window, but make sure to exit the second copy before returning from the DOS shell, or the first copy will abort. Finally, RBcomm returns the rest of its time-slice to DV if it doesn't need a full slice. This improves the performance of programs in other windows. ----------------------------------------------------------------------------- Dialing Directory ----------------- The dialing directory is a plain text file, containing up to twenty entries (any additional entries will be ignored). Each entry consists of two lines, looking like this, with no blank lines between entries: Doctor's WOC Inn 14128817757|4800N81|B|OPUS|password|\\N2 The first line contains the description which will be used in the dialing directory and when dialing. The second line contains six fields separated by vertical bars. These fields are 1. number to dial (direct connection if empty) 2. modem parameters, containing in order baud rate (110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600) parity (N for none, E for even, O for odd, S for space, M for mark) data bits (5, 6, 7 or 8) stop bits (1 or 2) handshake to use when receive buffer is full (H for hardware RTS/CTS, X for software XON/XOFF) (optional, default is hardware) timed call flag (if handshake present and the character after the handshake is T, a short "bip" will sound about 50 seconds into each minute after establishing a connection. Every five minutes, the "bip" sounds twice) serial port number (if handshake is present, following either the handshake character or the "T" timed call flag with a comma and the number of the serial port will tell RBcomm to switch to that port before dialing) 3. terminal emulation A for ANSI with VT102 extensions B for ANSI-BBS (same as ANSI, but clearing screen also homes cursor, character set switching is disabled, and the AVATAR level 0 command set replaces two RBcomm private commands) V for VT52 with H19 extensions 4. keyboard macro file to load 5. password for this system (used by PASSWORD macro command). Display of passwords in the dialing directory may be turned on or off with RBCONFIG. 6. optional modem setup string, minus command lead-in defined by RBCONFIG (may include vertical bars). In the example above, the \\N2 tells my modem to use MNP error correction. If the keyboard macro file field is non-empty, the specified file will be loaded immediately upon successfully connecting with the remote system. Since each entry in the dialing directory can specify an independent set of keyboard macros, you can have a different set of keyboard bindings for each system. If the macro file specifies a binding for the ONLOAD "key", that macro will be executed immediately. Further, if the macro file specifies a binding for the AUTO "key", that macro will be executed immediately after the ONLOAD macro (if any). The setup string may contain the following special sequences: ~ pause for half a second \n send a line feed \r send a carriage return \f send a form feed \t send a horizontal tab \a send a ^G \b send a backspace \! send a break \~ send a tilde \\ send a backslash Example modem parameters: 1200E71X default COM port, 1200 bps, even parity, seven data bits, one stop bit, use Xon/Xoff handshake when receive buffer fills up 19200N81HT,2 COM2, 19,200 bps, no parity, eight data bits, one stop bit, use hardware handshake, and sound off every minute ----------------------------------------------------------------------------- Environment Variables --------------------- RBcomm uses the following variables in its environment: COMSPEC specifies which program to load for Shell-to-DOS (Alt-D) and Execute-Program (Alt-G). RBCOMM overrides the default RBcomm data directory. The data directory is where RBcomm stores its dialing directory and all macro files. RBCDIAL overrides the default dialing directory file. Do not use a path in the value of this variable, only a filename and extension (which defaults to .DIR). The value of this variable will be appended to the data directory (either default or specified by the RBCOMM variable) to produce the name of the dialing directory. ----------------------------------------------------------------------------- Keyboard Commands ----------------- The commands described here may be bound to other keys, but the default keystroke named here may always be used when preceded by Alt-= (hold down the Alt key and press the equal sign at the upper right of the typewriter section of the keyboard). Alt-A attack dial Repeatedly dials the number you select from the dialing directory until a connection is established. You may also manually enter a number to attack-dial. Alt-B send break Alt-C call a number Dial the number you select from the dialing directory (once only). You may also manually enter a number to dial. If you are currently connected to another system, you will be prompted whether to hang up. Press Esc to abort the dial and return to the current session. Press "Y" to disconnect and then dial a new number, or "N" to maintain the current connection and load new macros and parameters without dialing. Note that the modem parameters always have an "H" appended when neither "H" nor "X" is present in the dialing directory, since the handshake defaults to hardware. Alt-D DOS shell Temporarily exit to DOS. Type "EXIT" to return to comm session. RBcomm will swap itself out of memory, leaving only 592 bytes plus its copy of the environment in memory. A 64K swap file will be created in the directory you specified with RBCONFIG, and will be deleted when you return to the comm session. File transfers also create the temporary swap file. Alt-E toggle local echo By default, RBcomm assumes that the remote system will echo any characters you need to see. After pressing Alt-E once, RBcomm will display any characters you type without requiring the remote system to echo them. After pressing Alt-E a second time, RBcomm will once again assume that the remote system will echo characters. Alt-F list files Display a three-up listing of the files matching a given filespec. Alt-G Go execute a program You will be prompted to enter a command. Everything up to the first blank is the program to execute (if it starts with an exclamation mark ['!'], the rest of the line is passed to COMMAND.COM, otherwise, you must specify a full path and extension--searching the path would significantly increase the size of the RBcomm executable), and the rest of the line is the command tail to pass to the program. Alt-H hang up Terminate the connection. First drops DTR, and if Carrier Detect is still active, sends the modem's hangup string. The default macro set is reloaded from disk (if present) or from the built-in defaults. If the CLEANUP "key" has a macro binding, it is executed before hanging up; if it includes the LOWER_DTR command, DTR will remain dropped. Alt-I idle This command allows you to keep a connection alive if you need to step away from your computer for a while. Sends a space followed by a backspace every two minutes (configurable with RBCONFIG) until you press a key to cancel the command. Alt-J jump to directory Pops up a window displaying the current directory. You may switch to a different directory by entering it in place of the displayed directory. Relative paths without a leading slash or backslash will change to a subdirectory of the current directory. If you specify a drive letter, that drive will become the current drive as well. Alt-K unused Alt-L toggle logging to file When pressed the first time, you will be asked for the name of a file to which all characters received from the remote system will be appended (percent signs introduce variable expansions--see the EXEC and OPEN_LOG commands below). When pressed the second time, RBcomm will no longer append received characters to that file. If verbose (see Alt-Y) is active, all characters will be appended exactly as received, otherwise any command sequences embedded in the received data are stripped out. Alt-M learn macro When you press Alt-M, you will be asked which key you want to assign the macro to. You may then enter a text string of up to 78 characters (if a TEXT macro is already assigned to the key, the current value becomes the default value in the input line), using the same editing keys used elsewhere. Alt-N unused Alt-O send file with slowed-down Zmodem This command will send the specified file(s) using the "slow" Zmodem parameters installed by RBCONFIG. (subject to change in future versions) Alt-P set parameters This command pops up a menu which allows you to set the following parameters: COM port, speed, parity, parity stripping, handshake, backspace translation, visual bell, and terminal emulation. You may also reset the terminal emulation to its initial state, in case the remote system leaves you stranded in a strange condition. Press Esc, Enter, or 'R' to exit this menu. Note that Alt-P will discard any characters which have been received but not yet processed, because it always reinitializes the serial port when it pops down. Alt-Q dial queue of numbers Repeatedly dials each number you specify until a connection is established with one of the numbers. The numbers are dialed in round-robin fashion until a connection is established. A beep will sound to notify you of the connection, and the name of the remote system and the modem's connect response will be displayed. You specify the numbers to dial by giving the digit or letter as it appears in the dialing directory (case is ignored on letters). A number may be specified more than once, and will be dialed more than once during a round of dialing attempts. As a shortcut, specifying an asterisk ('*') instead of a list of numbers will dial all numbers in the dialing directory in order. Alt-R receive file Pops up a menu allowing you to select the protocol with which you wish to receive a file from a remote system. Press ESCape if you do not wish to receive a file. Note that Zmodem features automatic download, so you do not need to press Alt-R unless you wish to give DSZ additional parameters. You may also add additional autodownloading protocols--see the WHEN macro command in the next section. Not listed on the menu: ^G, ^Y, and ^Z pop up a parameter prompt, then proceed with the download specified by the corresponding non-control letter. Alt-S send file Pops up a menu allowing you to select the protocol with which you wish to send a file to a remote system. Press ESCape if you do not wish to send a file. After selecting a protocol, you will be asked to enter the name of the file to send (Ymodem, Ymodem-G, and Zmodem allow wildcards and multiple filespecs). If you press the control character corresponding to the desired protocol, the file(s) will be deleted after a successful transfer. For batch transfers, only the files corresponding to the first filespec are deleted. Also unlisted on the menu: pressing 'R' (or ^R) will send with Zmodem using the "medium" parameters and pressing 'S' (or ^S) will send the file with Zmodem using the "slow" Zmodem parameters installed by RBCONFIG. Alt-T type ASCII file to other system sends an ASCII file to the remote system, pausing after each line for the return to be echoed. The send may be aborted at any time by pressing Escape. Alt-U load/save user interface as defined in keyboard macro file Note that keyboard macro files are always stored in the RBcomm directory as defined by RBCONFIG. WORDSTAR.RBM and EMACS.RBM contain the keyboard definitions for using WordStar (tm) and Emacs cursor movement commands on the cursor pad (i.e. Home goes to the start of the line, etc.) EMACS.RBM also binds all Alt-letter keys to be Esc-letter, making the Alt key into a true Emacs meta-key. You will need to use the Alt-= override to use the RBcomm commands while EMACS.RBM is loaded. Alt-V View file (toggle verbose, which used to be on Alt-V, is now on Alt-Y) Page through a text file. This is a very minimal file lister. Press the space bar to display next screenfull, Escape to quit. Alt-W unused Alt-X exit Terminate RBcomm. If you are still connected to the remote system (Carrier Detect asserted), you will be asked whether or not to hang up. Alt-Y toggle verbose (previously Alt-V) Toggles the verbose mode used with Alt-L. When not logging, the control characters which are not used for terminal commands will be displayed as ^X when received from the remote system. When logging to a file, terminal command sequences will only be stored in the log file if verbose mode is ON. Alt-Z send file with Zmodem This command will send the specified file(s) with the "medium" Zmodem parameters installed by RBCONFIG. Alt-1,2,3,4,5,6,7,8,9,0 dial first ten numbers in dialing directory Alt-F1 through Alt-F10 dial 11th through 20th number in dialing directory F1 pop up help screen Displays the contents of the help file for the current macro file (if that file is not found, RBcomm attempts to use RBCOMM.HLP). Press an Alt or function key to execute the default binding for the key. Escape exits immediately, and any other key pages through the help file (if more than 20 lines long). Alt-- cancel any pending WHEN, DELAYED, or WINDOW commands Alt-= use default binding of next keystroke If the keyboard has been redefined, pressing Alt-= will allow you to access the built-in default definitions (as listed in this section). Press Alt-= and then immediately press the key whose default definition you want to use. ----------------------------------------------------------------------------- Line Editor ----------- Whenever you are prompted for a line of input, you may use the following keys to edit the line: Esc abort Home move to start of line End move to end of line Right move a character right Left move a character left Del delete the character under the cursor and shift remainder of line left Backsp delete the character to the left of the cursor, and shift the remainder of the line left Return finish input Alt-D insert an ASCII DEL character Alt-E insert a literal Esc character Alt-H insert an ASCII backspace character Alt-M insert a literal Return character Alt-P insert the contents of the cut buffer ----------------------------------------------------------------------------- Warnings -------- Don't try to load a TSR while shelled to DOS. RBcomm won't be able to swap itself back in and will have to abort. Your connection will not be broken, however. Don't mess with the swap file while shelled. You'll be sorry.... (RBcomm is able to detect a missing or truncated swap file on returning, but not other changes) IMPORTANT: if you are swapping to a floppy drive, DO NOT UNDER ANY CIRCUMSTANCES replace that floppy disk while shelled to DOS or running a file transfer. You will definitely trash the file allocation tables and directory of the second disk. This is a problem with DOS itself (at least through 3.10, later versions may have corrected it) when faced with a diskette change while a file is open on the diskette which gets removed. The swap file is such an open file. ----------------------------------------------------------------------------- Known Bugs and Limitations -------------------------- Any OPEN_LOG command in the OnLoad macro will fail when the macro is loaded manually. There is no easy fix for this one, as it is tied in deeply with the way windows and the terminal emulator interact. If you are using a serial port which the BIOS does not recognize, you will need to get a program to initialize the port. Otherwise, RBcomm will most likely read garbage parameters from the port at startup, requiring you to set the parameters by hand with Alt-P. ----------------------------------------------------------------------------- Macro Compiler -------------- Syntax: MACRO {t|m} infile outfile where 't' specifies compilation from text file to keyboard macro file and 'm' specifies decompilation from macro file to text file default extensions are .MAC for text files and .RBM for macro files Important Note: RBcomm v3.1 and later macro files are COMPLETELY INCOMPATIBLE with earlier versions. You must recompile all your macro files. If RBcomm doesn't complain, you don't need to recompile. ------------------- Macro File Commands ------------------- Each command has the following form: keyname commandword [args] where keyname specifies to which key the command is to be bound. Keynames (which are not case-sensitive) are: F1 through F12 for the function keys +F1 through +F12 for the shifted function keys ^F1 through ^F12 for the control function keys @F1 through @F12 for the alt-function keys @A through @Z for the alt-letter keys @1 through @0 for the alt-digits Gray+, Gray-, Gray*, Gray/ for plus, minus, star, slash keys on keypad @Plus and @Minus, @Gr*, @Gr/ for Alt-Gray+, Alt-Gray-, Alt-Gray* and Alt-Gray/ Left, Right, Up, Down for the cursor keys on the numeric pad Home, End, PgUp, PgDn, Ins, and Del for the other keypad keys KP5 for the '5' key on the number pad (enhanced keyboard) ^Home, etc. for the control versions of the numberpad keys CP_Home Home key on gray cursor pad CP_Up Up arrow on gray cursor pad CP_Down Down arrow on gray cursor pad CP_Enter Enter key on cursor pad etc. @Left, @Right, @Up, @Down, @Home, @End, @PgUp, @PgDn, @Ins, @Del for Alt- versions of the cursor pad keys ^Left, ^Right, etc for Ctrl- versions of the cursor pad keys ^Break for control-break @- @= @[ @\ @] @; @' @, @. @/ @` @* for various other Alt-keys There are also some pseudo-keys to which you may assign a macro: "OnLoad" is executed any time the macro file is loaded into memory "Auto" is executed automatically when a connection is established "Reconnect" is executed automatically when reconnecting without hanging up and redialing "CleanUp" is executed when hanging up if carrier detect is active "OnAbort" is executed whenever a macro other than OnAbort aborts and displays the **ABORTED** message, just prior to displaying the message And there is a no-operation pseudo-key for use by FORCE_CLEANUP: "Null" does nothing and returns immediately You may assign macros to control keys by specifying "^x" as the key name, where "x" is the control key you want to use. Similarly, you may assign a macro to a regular key by preceding the character representing the key by a backslash. Note that macros are never in effect when you are prompted for information by RBcomm; they only affect what (if anything) gets sent to the remote system. Finally, you may use "#nnn" where nnn is the decimal scancode of the key you wish to assign the macro to (values of 200 through 255 are reserved, 167 through 199 are currently unused by any key combinations supported by the BIOS). Note that the cursor pad keys will execute the binding for the corresponding number pad key if not specifically bound (but not vice versa). CP_Enter defaults to the binding for @Enter. The commandword is not case-sensitive, but you must include the underscore if present and use the entire commandword (abbreviations are not supported). With the exception of the ANSWERBACK, TEST, TEXT, WAITFOR, and WHEN commands, all commands which take a string argument pop up a prompt if the string is empty (i.e. ""). Strings may include the following special sequences: ^x specified control character ^? ASCII DEL (127) \a ^G (bell) \b backspace \e escape \f form feed \n line feed \r carriage return \t horizontal tab \v vertical tab \\ backslash \^ carat \0 ASCII NUL (for TEXT command only) For character arguments, you may specify either 'c' where the character c is interpreted as for a string, or you may specify its ASCII value. Everything from a semicolon (unless it is in a string) to the end of the line is considered a comment, as are blank lines. If a line starts with #include rather than a key name, the specified file will be compiled into the macro file as if it were part of the current text file. Note that the string is processed just like any other strings, so that you must double any backslashes (or use forward slashes, instead). Format: #INCLUDE "d:/path/filename" an extension of .MAC is assumed if no extension is given, and the drive letter and path are optional (default is current drive and directory). #INCLUDEs may be nested up to twelve deep. If a line starts with #ignore rather than a key name, any subsequent occurrences of the keyname following the #ignore will be ignored, just as if you had already defined a binding for the key. This is useful when #include'ing a file if you do not want all the bindings in the included file. Format: #IGNORE <keyname> For readability, you may give names to extended keys with the #DEFKEY <newname> <keynumber> command. User names will be lost on decompiling the macro file, however. For example, "#defkey Proc1 199" will let you refer to "Proc1" and "#199" interchangeably. ABORT abort the current macro or operation as if the user had pressed Esc. ABORT_UNTIL Abort any currently executing UNTIL command after the command(s) it controls complete. If multiple UNTIL commands are nested, each is aborted as the commands it controls complete, until all pending UNTILs have been aborted. Useful mainly in conjunction with the DELAYED command to provide a timeout on UNTIL loops. See also DELAYED, UNTIL. ANSWERBACK "string" sets the answerback message to the specified string. If the string is empty (i.e. ""), answerback is disabled (making ^E a cursor-positioning command), otherwise, answerback is enabled. AT hh:mm:ss execute the following line (or lines if a MULTI) at the specified time. If the specified time is less than the current time, the command(s) will be executed the next day. The seconds may be omitted, in which case they default to 0. Note: the command(s) may actually execute later than requested if RBcomm is busy processing incoming characters at the time the command should execute. The command will execute as soon as RBcomm empties its receive buffer. See also DELAYED. AUTO_ZMODEM reenable Zmodem and Puma autodownloads if they have been canceled by an ENDWHEN. This is functionally equivalent to WHEN 0 "**^XB00" RECEIVE 'Z' WHEN 0 "^X^H^XPuma^X^H^X" RECEIVE 'P' The autodownloads are also reenabled when hanging up, dialing, or loading a new macro file. WARNING: do not invoke while autodownload is enabled, as you will wind up invoking a download multiple times for one download request.... Note: this command will be renamed to AUTO_XFER in a future release. See also ENDWHEN, WHEN. AWAITKEY pause until a key is pressed. The next function which reads a key will read the key which was pressed. Returns immediately if there was any typeahead (including RBcomm's key stack). See also KFLUSH. BEEP sound the bell. Useful mainly in conjunction with the MULTI or DELAYED commands (see below). BREAK send a break to the remote system CALL keyname execute the macro (if any) bound to the specified key and then continue executing the current macro (if inside a MULTI). See also GOTO_KEY, PUSHKEY. CANCEL_DELAYED which cancel the specified delayed action. Currently supported: ALL cancel all delayed actions LAST cancel the last executed DELAYED. If called a second time without an intervening DELAYED, the second call is ignored. See also DELAYED. CANCEL_NOTIFY remove the notify window immediately instead of at the end of the configured period of time. CHDIR "dir" change the DOS default directory to the specified directory. CLOSE_LOG close the current log file. If logging is off, this command has no effect. See also OPEN_LOG, TOGGLE_LOG. CUT num dir "search" search the screen backwards from the current cursor position until the search string (case sensitive) is found, then copy "num" characters in the indicated direction (AFTER or BEFORE) to the cut buffer. The contents of the cut buffer remain unchanged if the search string is not found (in which case the completion status is set to FAILED for testing by IF or UNTIL). The cut buffer may be sent to the remote system with the PASTE command, inserted into a line being edited by pressing Alt-P, or inserted with the %C variable expansion. Note that trailing blanks are deleted from the cut buffer. In addition, the CUT command treats the entire screen (even if a WINDOW command was used to restrict output to a portion of the screen) as a single long line, ignoring all line wrapping for both search and cut. Examples: Screen contains "1234test5678cursor here->" and the cursor is as indicated. Then CUT 3 BEFORE "test" places "234" into the cut buffer, while CUT 6 AFTER "test" places "5678cu" into the cut buffer. Further, CUT 7 BEFORE "" will place " here->" into the cut buffer. See also PASTE. DELAYED time execute the macro on the next line (or lines if it is a MULTI) the given amount of time from now. You may have up to six delayed commands active at any given time. The maximum delay time is 18 hours; the macro compiler will complain if you attempt to use a greater delay. Times are specified as seconds minutes:seconds or hours:minutes:seconds Note: the command may actually execute later than requested if RBcomm is busy processing incoming characters at the time the command should execute. The command will execute as soon as RBcomm empties its receive buffer. See also CANCEL_DELAYED, WHEN. DIAL number redial dial the specified entry (0-19) from the dialing directory, or pop up the dialing directory if 'number' is PROMPT. 'redial' specifies how to dial: ONCE make only one attempt ATTACK try repeatedly until connected RECONNECT make a single attempt if not connected, or set parameters and password without dialing if already connected See also LISTDIAL. ECHO ON|OFF ECHO ON forces half-duplex (local echo on) mode, ECHO OFF forces full-duplex (local echo off). (see Alt-E) See also TOGGLE_ECHO. ENDWHEN which cancel the specified WHEN command. Currently supported: ALL cancel all WHENs except the Zmodem and Puma autodownloads ALL_XFER cancel all WHENs including the autodownloads LAST cancel the last executed WHEN. A second call without an intervening WHEN acts the same as ENDWHEN ALL. See also WHEN. EXEC "command-to-execute" everything up to the first blank in the string specifies the program to execute (either full path and extension, or "!prog" to let COMMAND.COM find and fire up the program), the remainder of the string is the command tail to pass to the program. Note that a following IF command will always consider the EXEC to have succeeded if you use the !prog form (that's because COMMAND.COM does not pass on the completion status of the program it runs). Within the command tail, a percent sign introduces a variable substitution. The following sequences are supported: %a hexadecimal I/O base address being used %C contents of the cut buffer %d current date, in format mm-dd-yy %D current directory, including drive %i IRQ number being used (0-15) %I get input from user. The following characters up to the next percent sign are used as the prompt and then discarded. %M current macro file name %p port number (1-4) %P port parameters, in same format as dialing directory display %s current serial port speed %t current time, in format hh:mm:ss %V get an environment variable. The following characters up to the next percent sign are used as the name of the variable and then discarded. %% a percent sign See also EXECN, IF, SHELL. EXECN "command-to-execute" This command is identical to EXEC, except that no error box is displayed in the event of an error. See also EXEC. EXIT End RBcomm. Will prompt you whether or not to hang up if you are still connected to another system. FDELETE "filespec" delete the file(s) named by filespec (which may include wildcards). Note that there is no confirmation requested, so use this command with care!!! See also FILES. FILES "filespec" display a three-up list of the files matching the filespec See also FDELETE. FORCE_CLEANUP keyname execute the following line(s), then execute the macro bound to "keyname" regardless of how the commands are exited (i.e. normally, ABORT, or <Esc>). FORCE_CLEANUPs may be nested, in which case the innermost one is the only one to execute unless the cleanup code executes an ABORT itself (then execution gets passed to the one enclosing it, etc.). If no cleanup is needed and the FORCE_CLEANUP is merely being used to prevent a complete abort on Esc, the pseudo- key Null may be used. Null is guaranteed to perform no action and return immediately. GOTO_KEY keyname continue execution with the specified macro (if bound). Never returns to the current macro. If the key is not bound (i.e. GOTO_KEY Null), execution resumes at the point from which the current macro was CALLed, effectively producing a return from a nested macro. See also CALL, PUSHKEY. HANGUP hang up. Executes macro bound to "CleanUp" before actually hanging up if carrier detect is active. After hanging up, the default macro file is reloaded (thus cancelling any remaining WHENs and DELAYEDs). See also HANGUP_ONLY. HANGUP_ONLY hang up, but do not execute the "CleanUp" macro or reload macro files. See also HANGUP. HELP pop up the help screen IDLE go into idle mode, sending a blank followed by a backspace every 2 minutes. Press Esc to end idle mode. Both the interval and the sequence sent by idle mode may be configured with RBCONFIG. IF SUCCESS|FAILED|CONNECTED|OFFLINE|DV|NOT DV IF SUCCESS and IF FAILED conditionally execute a command based on the completion status of an immediately preceding EXEC, SHELL, SEND, SENDFILE, RECEIVE, RECEIVEFILE, or WAITFOR. The following line (or lines if a MULTI) is executed only if that prior command was successful in the case of IF SUCCESS, or if it failed in the case of IF FAILED. IF CONNECTED executes the following command if carrier detect is asserted, while IF OFFLINE executes the following command if carrier detect is deasserted. IF DV executes the following command if RBcomm has detected that it is running under DESQview, while IF NOT DV executes the following command only if RBcomm is not running under DESQview. For example, if you want to execute a program only after failing to see a particular string, you would use MULTI WAITFOR 10 "don't run program" IF FAILED EXEC "!someprog args" END See also ABORT_UNTIL, EXEC, SHELL, SEND, RECEIVE, WAITFOR, UNTIL. KFLUSH empty the keyboard buffer (including RBcomm's key stack). See also AWAITKEY. LEARN start learning a keyboard macro See also UI_MENU. LISTDIAL "numbers" dial the specified numbers from the dialing directory repeatedly until a connection is established with one of the numbers. If the empty string is specified, the user will be prompted for the numbers to dial. See also DIAL. LOAD_MACRO "file" load the specified macro file from the RBcomm directory. If an empty filename is given, the user will be prompted for a name, which defaults to the name of the currently loaded macro file. The current macro (if any) and any that it had interrupted are aborted. However, if the interruption occurred during a command of extended duration such as a WAITFOR, that command will complete normally before the macro is aborted. See also SAVE_MACRO, UI_MENU. LOG "filename" "message" append the specified message to the named file. Both the filename and the message may contain variable expansions as described under EXEC. If the filename is (or expands to) the empty string "", the expanded message is appended to the current log file (if any). See also OPEN_LOG. LOWER_DTR requests that DTR remain dropped after the next HANGUP or HANGUP_ONLY command. The best place to put this command is in your CleanUp macro. MESSAGE row col msg display the specified message starting at the given row and column on the screen. If either row or column is 255, use the current row or column. MESSAGEBOX msg if running under TopView or DESQview, a window with the given message will pop up for three seconds. This command is ignored otherwise. The message is limited to 40 characters, anything beyond that is ignored. See also NOTIFY, CANCEL_NOTIFY. MULTI the following lines, up to but not including a line starting with END, are assigned to the specified key. The macros assigned to the key may not total more than 253 bytes, and the macro compiler will complain if they do. The format of the following lines is the same as for a regular macro, except that you do not specify a keyname. For example, to make shift-F2 switch terminal emulation to VT52, use +F2 MULTI PUSHKEY 13 0 PUSHKEY 'V' 0 PARAM_MENU END Note: you may use { and } on separate lines as synonyms for MULTI and END. NOTIFY msg if running under TopView or DESQview, and RBcomm determines that it is in the background, a window with the given message will pop up for three seconds. This command is ignored otherwise. The message is limited to 40 characters, anything beyond that is ignored. See also CANCEL_NOTIFY, MESSAGEBOX. OPEN_LOG "file" if logging is on, the current log file will be closed. Then, the specified log file will be opened (if no name is given, a prompt is popped up). The same variable expansions which are valid for the EXEC command are applied to the filename which is given (or entered by the user). For example, to allow the environment variable RBLOG to specify the base name of the log file, use OPEN_LOG "%VRBLOG%.LOG" See also EXEC, CLOSE_LOG, TOGGLE_LOG, RECEIVE. PARAM_MENU pop up the "Set Parameters" menu PASSWORD send the password defined in the dialing directory. Does not send a carriage return or any other terminating sequence. See also TEXT, TYPE. PASTE send the contents of the cut buffer to the remote system. See also CUT. PAUSE num-ticks halt execution for num-ticks/18 seconds. Useful mainly in conjunction with the MULTI command (see above). PUSHKEY key scan or PUSHKEY keyname put the specified key/scancode pair onto RBcomm's internal keyboard stack, where the last pushed pair will be the next keystroke read by RBcomm. The stack is currently eight keystrokes in size, and any PUSHKEY executed while the stack is full will simply be ignored. "keyname" may be the name of any keystroke recognized by the macro compiler. Useful mainly in conjunction with the MULTI command (see above). RECEIVE 'type' start receiving a file with the specified protocol 0 prompt for protocol 'A' ASCII (capture to file--equivalent to OPEN_LOG "") 'X' Xmodem with parameters 'K' Xmodem-K with parameters 'Y' Ymodem '^Y' Ymodem with parameters 'G' Ymodem-G '^G' Ymodem-G with parameters 'Z' Zmodem '^Z' Zmodem with parameters See also IF, OPEN_LOG, SEND, TYPE. RECEIVEFILE 'type' "parameters" start receiving using the specified protocol (which may be any of the ones listed for RECEIVE except 0 or 'A'), passing the specified parameters to the file transfer module. Unlike RECEIVE, this command will not pop up any messages unless it is unable to load the file transfer module; in case of an error, the completion status is set to FAILED. See also RECEIVE, SENDFILE. REPEAT times repeat the command on the next line (or lines if a MULTI) the specified number of times. RFLUSH clear any characters which may still be in the serial port receive buffer. See also KFLUSH. SAVE_MACRO "file" save the current macros to the specified file, located in the RBcomm directory. See also LOAD_MACRO, UI_MENU. SEND 'type' prepare to send a file with the specified protocol 0 prompt for protocol 'A' ASCII 'X' Xmodem 'K' Xmodem-K 'Y' Ymodem 'G' Ymodem-G 'Z' Zmodem 'R' reduced-speed (medium) Zmodem 'S' slow Zmodem control character versions of any of the above ('^X', '^Y', etc) will delete the file(s) corresponding to the first filespec after sending. See also IF, SENDFILE, RECEIVE, TYPE. SENDFILE 'type' "file" send the specified file with the given protocol, which may be any of the ones listed for SEND except 0 or 'A'. Unlike SEND, this command will not pop up any messages unless it is unable to load the file transfer module; in case of an error, the completion status is set to FAILED. See also RECEIVEFILE, SEND. SHELL shell to DOS See also EXEC, IF. TEST EXISTS "filespec" determine whether any files matching the filespec exist. Sets the status to SUCCESS if at least one exists, FAILED if none. The status may be checked with IF or UNTIL commands. See also TEST WHEN, IF. TEST WHEN "str" determine whether a WHEN with the specified search string is currently active. Sets the status to SUCCESS if at least one exists, FAILED if there are no WHENs with the specified string. The status may be checked with IF or UNTIL commands. See also IF, WHEN, TEST EXISTS. TEXT "msg" send the specified characters out the comm port. "msg" is limited to 253 characters. TOGGLE_ECHO toggle the state of local echoing See also ECHO. TOGGLE_LOG if logging is currently on, turns off logging received data to file if logging is off, pops up a prompt for the name of the capture file See also OPEN_LOG, CLOSE_LOG. TOGGLE_VERBOSE toggle the state of verbose mode (see Alt-Y) See also VERBOSE. TRANSLATE_BS ON|OFF TRANSLATE_BS ON turns on backspace/delete swapping, TRANSLATE_BS OFF turns it off. TYPE "file" send the specified file to the remote system as a stream of ASCII characters. Pauses at the end of each line and waits for the carriage return to be echoed (will continue after three seconds even if the echo is not seen). Equivalent to SEND 'A' if no filename is given. See also SEND. UI_MENU pop up the load/save macro menu See also LEARN, LOAD_MACRO, SAVE_MACRO. UNTIL SUCCESS|FAILED|CONNECTED|OFFLINE repeatedly executes the following line (or lines if a MULTI) until the status of the last action is either success for UNTIL SUCCESS or failure for UNTIL FAILED. UNTIL CONNECTED repeatedly executes the following command until carrier detect becomes active, while UNTIL OFFLINE repeats until carrier detect drops. See also ABORT_UNTIL, IF. VERBOSE ON|OFF VERBOSE ON turns on verbose mode, VERBOSE OFF turns off verbose mode. (see Alt-Y) See also TOGGLE_VERBOSE. VIEW "filename" display the specified file one screenfull at a time. Pops up a prompt if the null filename is given. Pressing the space bar displays the next screen, Escape exits the file view. WAITFOR timeout "wait-string" wait up to timeout seconds for the specified string of characters to arrive over the comm port. Useful mainly in conjunction with the MULTI command (see below). You may test whether the string was actually received by following the WAITFOR with IF SUCCESS or IF FAILED (unlike versions prior to 3.11, a failed WAITFOR does not abort the MULTI it is a part of). See also IF. WHEN iterations "when-string" execute the command on the following line (or lines if it is a MULTI) whenever the "when-string" is encountered in the data stream coming from the remote system. After the string has been encountered "iterations" times, the WHEN is automatically canceled (if iterations is zero, the WHEN must be explicitly canceled with ENDWHEN). You may have up to six WHENs active at any time (eight if you cancel the autodownload [see ENDWHEN above]). All WHENs are canceled on hanging up or dialing a number, and autodownload is re-enabled. WHENs are tested in the order in which they were executed, so multiple WHENs with the same when-string will trigger in the order in which they were asserted. This can be an extremely powerful command. For example, you can implement another autodownloading (or uploading!) protocol simply by adding WHEN 0 "start-string" EXEC "xfer-program parms" to the AUTO or OnLoad macro. On CompuServe, you can make Ymodem autodownloading by adding WHEN 0 "initiate YMODEM receive" RECEIVE 'Y' to the OnLoad macro. The built-in Zmodem autodownload corresponds to WHEN 0 "**^XB00" RECEIVE 'Z' while Zmodem auto-upload can be added with WHEN 0 "**^XB01" SEND 'Z' The standard Puma autodownload is equivalent to the lines WHEN 0 "^X^H^XPuma^X^H^X" RECEIVE 'P' [thanks to Matthew Thomas for publishing his autodownload string!]. See also DELAYED, ENDWHEN. WINDOW row col width height limit the terminal emulator to a portion of the full screen. WINDOW 0 0 255 255 will restore use of the full screen regardless of the screen size. ----------- Time Limits ----------- The maximal time intervals which may be specified for various commands are: 255 ticks (~14 seconds) PAUSE 255 seconds (4.25 minutes) WAITFOR 18 hours (64800 seconds) DELAYED ----------------------------------------------------------------------------- Terminal Emulation ------------------ RBcomm supports four terminal emulations. ANSI provides standard ANSI escape sequences plus most VT102 and many VT200 escape sequences. BBS is identical to ANSI except that clearing the screen with Esc-[-J or Esc-[-2-J also homes the cursor, and character set switching is disabled. AVATAR is identical to BBS except that two of RBcomm's private commands are replaced by the AVATAR level 0 command set. Finally, VT52 replaces many of the Esc-letter sequences in ANSI with the actions a VT52 or H19 would perform. In addition, in all of these modes, RBcomm has its own, much more compact command set. ------------------ Control Characters ------------------ ^A move cursor up a line (will become ^^ in the next release) ^B move cursor right one position ^C move cursor down a line ^D move cursor left one position, does not wrap to previous line ^E send the answerback string to the remote system ^F special sequences (see below) ^G sound bell, or flash screen if visible bell enabled ^H move cursor left one position, wraps to previous line ^I move to next tab stop ^J move cursor down a line, scrolling screen when at bottom ^K insert a blank line ^L clear screen and home cursor ^M move cursor to start of line ^N "shift out"--switch to G1 character set (VT100) ^O "shift in"--switch to G0 character set (VT100) ^P clear rest of line ^R clear rest of screen ^T change character attribute to underlined ^U clear underlined attribute ^V (BBS) start of an AVATAR command (see below) (other) change to reverse video ^W cancel reverse video ^X insert a blank at the cursor's position, push rest of line right ^Y (BBS) repeat the following character the number of times specified by the second character after the ^Y (other) delete character at cursor position, rest of line shifts left ^Z delete line cursor is on ^[ escape sequence (see below) ^\ turn on insert mode ^] turn off insert mode ^^ move cursor up a line ^_ the following two characters (less 32) specify the new cursor column and row. i.e. ^_-blank-blank homes the cursor. ---------------- Escape Sequences ---------------- Esc-blank-F turn off eight-bit control characters Esc-blank-G turn on eight-bit control characters. When eight-bit control characters are enabled, many of the characters from 80h through 9Fh are equivalent to Esc-<char-40h>. Esc-( (VT100) next character ('0', '1', '2', 'A', or 'B') sets G0 character set Esc-) (VT100) next character ('0', '1', '2', 'A', or 'B') sets G1 character set Esc-# (VT100) next character sets character size only '8' implemented -- fill screen with 'E's for alignment display Esc-7 save cursor Esc-8 restore cursor Esc-< set terminal emulation to ANSI Esc-= set keypad application mode (if allowed to change NumLock by RBCONFIG) Esc-> set keypad numeric mode (if allowed to change NumLock by RBCONFIG) Esc-@ turn on insert mode Esc-A move cursor up Esc-B move cursor down Esc-C move cursor right Esc-D (ANSI) "index"--move cursor down, scroll if at bottom (VT52) move cursor left Esc-E (ANSI) move to start of next line, scroll if at bottom (VT52) clear screen Esc-F (ANSI) not implemented (VT52) select graphics character set Esc-G (ANSI) not implemented (VT52) select text character set Esc-H (ANSI) set horizontal tab at current position (VT52) home cursor Esc-I (ANSI) horizontal tab (VT52) reverse linefeed, scrolls down if already on top line Esc-J (ANSI) not implemented (VT52) clear to end of screen Esc-K (ANSI) not implemented (VT52) clear to end of line Esc-L (ANSI) not implemented (VT52) insert a new line at cursor Esc-M (ANSI) "reverse index"--cursor up, reverse scroll if at top (VT52) delete cursor line Esc-N (ANSI) not implemented (VT52) delete char at cursor, rest of line shifts left Esc-O (ANSI) not implemented (VT52) turn off insert mode Esc-Y move cursor, next two characters are row + 32, column + 32 Esc-Z request identification (ANSI) RBcomm returns the string "rbcommN.NNx" where N.NN is the version number and "x" is a single byte identifying implemented capabilities bit 0: screen storing implemented (set) bit 1: file transfer implemented (set) bit 6: always set (makes character printable) remaining bits reserved (VT52) RBcomm returns the string Esc-/-Z, indicating a VT100 emulating a VT52. Esc-[ ANSI sequence, see below Esc-] Operating System Command. The following characters through an Esc-\ sequence (maximum 80 characters) are skipped, as this command has no effect. Esc-^ ANSI Privacy Message. The following characters through an Esc-\ sequence (maximum 80 characters) are accumulated. If running under DESQview, the first 40 are displayed in the notification window; otherwise, the accumulated characters are discarded. Esc-_ Application Program Command. The following characters through an Esc-\ sequence (maximum 80 characters) are skipped, as this command has no effect. Esc-c reset to initial state Esc-j save cursor position (Heath H19) Esc-k restore cursor position (Heath H19) Esc-l erase line (Heath H19) Esc-p turn on bold characters Esc-q turn off bold characters Esc-v turn on line wrap (Heath H19) Esc-w turn off line wrap (Heath H19) Esc-z reset terminal emulation (Heath H19) -------------- ANSI Sequences -------------- All of the sequences listed here consist of Esc-[ followed by zero or more numbers separated by semicolons followed by the command letter. Therefore, only the command letter will be listed. X1, X2, etc refer to the specified numeric argument, and usually are followed by a default value in parentheses.

Does not affect any other settings = set terminal emulation to ANSI-BBS. Does not affect any other settings. > set terminal emulation to VT52. Does not affect any other settings. ? query terminal emulation type. Sends back <127><type> where type is 'A' for VT102/ANSI, 'B' for ANSI-BBS, 'V' for VT52, and 'U' for UW. @ send identification (see Esc-Z) A if next character is '0' through '7', save the current screen in the specified slot. This may silently fail if there is not enough memory available (thus the remote system must be capable of redrawing the screen itself). For technically minded: Screens are first stored in the near heap, then in the far heap (to store all ten screen requires a memory partition of about 85K using 80x25 screens, more if the screens are larger). Any screens in the far heap are lost when swapping, such as running DSZ or shelling to DOS. Using a 65K partition will allow you to store four or five screens in the near heap, none in the far heap. Note: this command will change in the next release B if next character is '0' through '7', restore the screen from the specified slot where a screen should have been previously saved with ^FA. If no screen has been saved in the slot, command fails. Sends a response of 127-<digit>-<status> to the remote system, where the digit is the slot number from the ^FB command, and status is 'Y' if the screen was restored or 'N' if the screen remains unchanged. Note: this command will change in the next release C if next character is '0' through '7', free the specified slot, so that it is as if no screen had ever been saved there. Note: this command will change in the next release ------------------------ AVATAR command sequences ------------------------ ^V^A set screen attribute to low seven bits of following character ^V^B set blink ^V^C move cursor up a line ^V^D move cursor down a line ^V^E move cursor left one space ^V^F move cursor right one space ^V^G clear from cursor to end of line ^V^H<r><c> move cursor to row <r> and column <c>, where the upper left corner is 1,1 ^V^I turn on insert mode until next AVATAR command (except ^Y and ^V^Y) ^V^J scroll area up. Next five characters specify number of lines to scroll, top margin, left margin, bottom margin, and right margin (all margins are based on 1,1 being the upper left corner of the screen) ^V^K scroll area down. Next five characters are as for ^V^J ^V^L clear area. Next three characters specify screen attribute for cleared area, number of lines less one, and number of columns less one. The blink bit of the attribute is ignored, and the current display attribute is set to the attribute of the cleared area. ^V^M fill area. Next four characters specify screen attribute for filled area, character to fill with, number of lines less one, and number of columns less one. The current display attribute is set to the filled attribute with blinking turned off. ^V^N delete character at cursor position ^V^Y repeat pattern. The following character specifies the length of the pattern to be repeated, followed by the pattern, and finally followed by a single character indicating the number of times to repeat the pattern. The pattern may contain command sequences, but is limited to 80 characters (longer patterns are truncated to 80 characters). ----------------------------------------------------------------------------- Acknowledgements ---------------- Thanks to Thomas Zerucha for his numerous comments and suggestions, many of which have been implemented.
