87ERROR.DOC
The program 87ERROR.COM is a simple 8087 error interrupt handler for
the IBM Personal Computer. To install the error handler just run 87ERROR.COM
from DOS (ver. 1.1, 2.XX). When an error interrupt is generated by the 8087
a letter in reverse video will appear in the upper right hand corner of the
monochrome display. The letter will indicate the general type of error which
caused the 8087 to generate an interrupt as below in the table:
D --------- Denormalized operand
Z --------- Divide by zero
O --------- Overflow
U --------- Underflow
P --------- Precision error
The interrupt pin on the 8087 is connected with the parity checking
logic on the mother board. Because of this fact the program needs to jump to
the ROM BIOS just in case the NMI (Non Maskable Interrupt) was generated by a
parity error and not by the 8087. The address of the jump at the end of the
interrupt handler "JMP FAR PTR ROMADR" may need to be changed depending on
what version of the IBM ROM BIOS you have.
The correct address can be found at 0H:8H to 0H:0BH for the jump to the
IBM ROM BIOS. The first two memory locations contain the offset and the next
two memory locations contain the segment address. Change the address on the
line "ROM SEGMENT AT 0F000H" to the segment address just found. Then
change the address on the line " ORG 0E2C3H" to the offset address
just found. You can now generate a new 87ERROR.COM file from the new
87ERROR.ASM source file.

ANSI&2K.SYS and Function Key Assignments
Bob Ketcham
About ANSI.SYS
One of the more powerful features of DOS 2.0 is the Extended Screen and
Keyboard Control provided by the ANSI.SYS device driver. Using ANSI.SYS you
can reassign the meaning of any key on the keyboard.
A Bigger ANSI.SYS
The power of ANSI.SYS is limited by the size of the buffer used to store
keyboard reassignments. The original buffer size is approximately 200 bytes.
ANSI&2K.SYS is a revised version of ANSI.SYS. The keyboard reassignment
buffer has been enlarged by 2K (2048 BYTES).
Installing ANSI&2K.SYS: The CONFIG.SYS File
As stated above, ANSI&2K.SYS is an installable device driver.
Installation of a device driver requires the use of a file called CONFIG.SYS.
The CONFIG.SYS file's function is similar to that of the AUTOEXEC.BAT file.
Like AUTOEXEC.BAT, the system looks for the CONFIG.SYS file on the disk with
which the system is booted (started). In a manner similar to the way the
system looks for and runs programs listed in the AUTOEXEC.BAT file, the
system looks for and loads device drivers listed in the CONFIG.SYS file. A
sample CONFIG.SYS file is provided with ANSI&2K.SYS. It should be copied
(along with ANSI&2K.SYS) to the disk you use to start your system. When the
machine is reset, ANSI&2K.SYS will be loaded as a device driver. Note if the
file CONFIG.SYS is not found with this documentation, use an editor to create
a file called CONFIG.SYS containing the line "DEVICE = ANSI&2K.SYS"
Keyboard Reassignment Using The TYPE Command
The documentation for this feature of DOS 2.0 is found in Chapter 13 of
the DOS manual. It states "The control sequences defined below are valid
only when issued through DOS function calls 1, 2, 6, and 9, ...". Simple,
any novice knows what a DOS function call is. Well, its simpler than that.
Any file which is displayed on the screen using the TYPE command is passed
through one of the required function calls. A sample file, KEYS is provided
along with this documentation file. After ANSI&2K.SYS is installed, the DOS
command TYPE KEYS will assign a set of frequently used DOS commands to the
forty combinations of function keys F1-F10, Shift, Ctrl, and Alt.
Assigning and Displaying Function Key Assignments with KEYS
The file KEYS consists of two primary sections. The first section
contains the escape control sequences which are used by ANSI&2K.SYS to do the
keyboard reassignments. When the TYPE command is used to display the file,
this section will be invisible. (The screen will clear and the flicker of the
cursor may be seen, but nothing more.)
The second section displays the key assignment information to the user.
Note that while cryptic commands may be assigned to the function keys, an
english language translation may be displayed here.
Modifying KEYS - Your Own Custom Keyboard
An editor is required to modify KEYS. Three which can be used are
EDLIN, FRED, or VEdit. Each has its advantages and disadvantages in this
application.
EDLIN is the DOS line editor provided with your copy of DOS. That is
its advantage. If you use it, you will know its disadvantages.
FRED is the FRee EDitor distributed using the Freeware concept. In
addition to the advantage of being free, it is friendly, easy to use, and
fast. It shares two disadvantages with EDLIN; it cannot be used to place the
escape character (BASIC CHR$(27)) in a file, and it always places a carriage
return and line feed at the end of the file. (KEYS will scroll the top line
off the screen if there is a CR-LF at its end.) Note: although the Escape
character cannot be inserted into a file with EDLIN or FRED; if it is already
there (as it is in KEYS), the editors's copy functions may be used to move
and duplicate it.
VEdit is a powerful commercial editor, which can insert the Escape
character into text. It will allow you to leave the CR-LF sequence off the
end of the last line if desired. Additionally it is smaller than FRED, so it
is convenient to place on most disks. However, many of its command syntaxes
are cryptic. I would not recommend it to the novice.
What's in KEYS - the ESCape Control Sequences
KEYS contains ESCape control sequences similar to the examples on page
13-11 of the DOS manual. Sequences are provided for the forty combinations
of function keys F1-F10, Shift, Ctrl, and Alt.
Each sequence begins with the escape character. In the DOS manual this
is shown as "ESC". Other representaions are:
- BASIC - CHR$(27)
- FRED - an arrow pointing left
- VEdit - ^[ (one character)
- Hexidecimal - 1B
- Decimal - 27
- Keyboard - Esc.
Following the ESCape character is the left square bracket ([). Each
control sequence for keyboard reassignment ends with a lower case p. Between
[ and p are characters which identify the key to be reassigned and the
reassignment to be made. For example the F1 key is assigned the string "Dir
/p" followed by a carriage return. The control sequence to do this is:
ESC[0;59;"Dir /p";13p
where: represents:
0;59; the F1 key. It sends the system two characters when struck;
A NUL (0) followed by decimal 59.
"Dir /p"; obviously the string "Dir /p".
13 carriage return (decimal 13)
Notice the use of the semicolon as a delimiter.
Getting Back to Normal - NULLKEYS
Another file of keyboard reassignment control sequences is provided. The
command TYPE NULLKEYS will return the forty function combinations to their
normal state.
Suggested Use
When used with a set of batch files, KEYS, ANSI&2K.SYS, and CONFIG.SYS
can provide an excellent Main Menu on a hard disk system.

FLOATING-POINT BENCHMARK
The following is a program to test the accuracy of floating
point functions (from Sept. DR DOBBS):
10 A=1
20 FOR I%=1 TO 2499
30 A=TAN(ATN(EXP(LOG(SQR(A*A))))) + 1
40 NEXT
50 PRINT A
60 STOP
The correct printout is A=2500 exactly.
IBM-PC BASIC 1.0 fails miserably, giving A=2179.8 (only 1 sig-
nificant figure of accuracy!). In contrast, an APPLE II or
Commodore 64 gives 2500 to at least 7 figures. Using the 8087
with a polyFORTH version of the benchmark, I obtained 2500 to
13 figures in 5.0 seconds. (NOTE: See March,84 D. DOBBS for
the results aginst many systems.)

The following is a cross reference of IBM PC DOS commands to their
"equivalent" (more or less) CP/M counterparts. This file should be
useful to users familiar with CP/M and CP/M public domain files. Some
of the files referenced ARE NOT public domain, however.
IBM PC DOS VERSION 2.O (not 1.0 or 1.1) is being referenced, and it
contains many commands and features not available under, or compatable
with, older versions.
CP/M version 2.xx is being referenced, and I am aware that many of
the public domain and dealer supplied utilities have varying names for
similar programs. I have made no attempt to present a comprehensive
listing of CP/M filenames for similar functions. The CP/M novice will
have to seek help from experienced CP/M users for that information.
In some cases, there is no equivalent feature or command, so I have
left a blank to indicate this (or for others to fill in!).

SYSTEM REQUIREMENTS
DEFRAG requires BASICA and PC-DOS 2.0. It may work on other IBM-PC lookalikes,
but other hardware/software combinations have not been tested.
OVERVIEW
DEFRAG was written to facilitate de-fragmenting PC-DOS diskettes. If you are
continuously modifying the files on a diskette it does not take long for the
files on the diskette to become `fragmented', i. e., the files will consist of
several groups of non-contiguous tracks and/or sectors. This `fragmentation'
of allocated space causes two problems: (1) Existing files take much longer to
load because of excessive disk drive head movement across multiple tracks, and
(2) New files get allocated in non-contiguous blocks because of `fragmented'
free space on the diskette. Thus, the fragmentation problem tends to become
self propogating.
The DOS Manual recommends using COPY *.* to copy all the files on a fragmented
diskette to a new one. Doing this will `collect' all the non-contiguous parts
of each file into one single block on the target (new) diskette. However,
COPY *.* copies the files in the order they appear in the source diskette
directory -- and this may not be the order you want them in. For instance,
it is best to have frequently used files first on the diskette so they can be
close to the diskette directory. This way disk arm movement is minimized when
these frequently used files are accessed.
DEFRAG overcomes this problem by providing the following capabilities:
1. Full screen display of all files in the directory sorted
alphabetically.
2. The ability to select, via the cursor control keys, any
or all of the files on the diskette in any order.
3. Automatic invocation of the DOS COPY utility to copy the
files in the order selected.
In addition, DEFRAG allows:
4. The ability to delete selected files.
5. The ability to invoke any DOS command without leaving
the program.
METHOD OF OPERATION
DEFRAG uses the SHELL command to read directories, sort their contents, copy
files, and invoke DOS commands. It uses Function Key interrupt processing
to read the various Function Keys and Cursor Control Keys. These are all
BASICA/DOS 2.0 capabilities.
When DEFRAG starts it requests input of three disk drive identifiers:
Work (RAM) drive: this is where DEFRAG will place the sorted
directory contents. If you have RAM drive
DEFRAG will copy COMMAND.COM and SORT.EXE
there; this greatly speeds up execution.
Source drive: this is the drive containing the diskette that
DEFRAG is to copy from. Nothing is written by
DEFRAG to this diskette. Files selected for
Peninsula Software - 28510 Blythewood Drive - Rancho Palos Verdes CA - 90274
=== D E F R A G ===
deletion are deleted from the source disk, not
the target disk. Deletion normally takes place
after copying.
Target drive: this is the drive containing the diskette DEFRAG
is to copy to; i. e., files will be copied from
the source disk to the target disk.
The Function Keys are used as follows:
F1: select a file for copy or delete
F2: restart DEFRAG allowing new source/target disk specifications
F3: copy all selected files from source disk to target disk
F7: delete all selected files from source disk
F9: allow input of any DOS command, then perform it
F10: end DEFRAG and return to BASIC (not DOS)
Arrow (cursor control) keys: move cursor around display of files to allow
individual files to be selected by F1
RESTRICTIONS/LIMITATIONS
1. DEFRAG does not handle sub-directories.
2. DEFRAG assumes SORT.EXE and COMMAND.COM are on Drive a:
3. If you respond other than a: to the location of the work (RAM) drive,
DEFRAG copies SORT.EXE and COMMAND.COM there and then patches DOS to
use those files instead of the ones on drive a:. This occurs only if
the work (RAM) drive is specified as being different from drive a:.
Note that DEFRAG will reset DOS to use COMMAND.COM on drive a: when
it ends, and it will delete all files it created from the work (RAM)
drive. DEFRAG must be allowed to end normally, i. e., by F10, if this
`cleanup' is to occur.
4. F9 allows you to invoke any DOS command. This can be dangerous. You
cannot execute BASIC however, since only one copy of BASIC (actually
BASICA) can be functioning at one time. Remember that any DOS command
you invoke will end up returning to DEFRAG, not to DOS, so don't do
things like deleting DEFRAG's work or PIPE files.
5. DEFRAG resets all 10 function keys when it ends. These specifications
can be easily changed if you prefer different assignments.

DOS2A.TXT
Here's some more information on DOS 2.0 interrupts:
The DOS critical section flag may be interrogated from
within an interrupt handler before requesting DOS
services:
MOV AH,34h
INT 21h
returns in ES:BX the address of a byte indicating (when
set) that DOS is in an uninterruptible state, and no DOS
calls should be made.
To access DOS' PRINT capabilities:
MOV AH,func
INT 2Fh
where:
AH = 0 adds the file specified by DS:DX to the
print queue. DS:DX must point to valid
opened FCB.
AH = 1 cancels the file indicated by DS:DX.
DS:DX must point to an FCB, opened or
unopened. The drive byte must not be 0.
Wildcards are restricted: ? is okay, *
isn't.
AH > 1 do nothing.
Return with registers set as follows:
DS,SI,DI,CX preserved, all others destroyed.
AH = number of files currently in queue.
AL = for AH=0, return 1 if queue was
full. For all other cases, return 0.
ES:BX = pointer to list of 10 FCBs in
queue, 38 bytes/FCB. If the first
byte of an FCB is -1, that FCB is
unused.
ES:DX = pointer to currently printing
FCB. If the queue is empty, DX = -1.
ENVXPAND.DOC
ENVXPAND: Expand your ENVIRONMENT to 1K
DOS 2.0 and later releases give you and your programs the means to
communicate through ENVIRONMENT strings, but no way to expand the rather
cramped space originally allotted for the purpose. Since PATH, COMSPEC and
any prompt you may set all go there, you quickly run out.
ENVXPAND provides a way of expanding your environment to 1024
bytes, which should give you plenty of space for most uses. The original
DOS strings take up less than an eighth of this space.
Thus you have plenty of space for a long path statement -- or for
a complicated prompt string (see the ANSI.SYS writeup for possibilities)
-- or to make use of the new environment functions of BASIC 3.0.
As a side benefit, ENVXPAND gives you a large keyboard buffer, too.
To use ENVXPAND, just follow these two easy steps:
Step 1: Add the following line to your CONFIG.SYS file:
DEVICE=ENVXPAND.SYS
This line should be the first one in your CONFIG.SYS file, ahead
of any other installed devices or programs.
Step 2: Rename your AUTOEXEC.BAT file on that disk or diskette to
AUTOEXEK.BAT.
Next time you boot from that disk or diskette, the system will
expand your ENVIRONMENT string space to 1K. It does this by adding
place-holder strings PH0 through PH9 to your ENVIRONMENT through the SET
command and then removing them. (You cannot do this from a BAT file and
it is tedious to do it from the keyboard every time you boot.) Finally,
ENVXPAND runs your AUTOEXEK.BAT file just as DOS runs your AUTOEXEC.BAT file
under normal circumstances.
That's all there is to it. There are no co-residence problems because
no new programs or interrupt handlers have been added to your system, only
environment and keyboard buffer space.
Also included is the program ENVINUSE.COM. It will tell you how much
of your ENVIRONMENT space is in use, including the null (00) delimiters of
the strings. You will find that you can fill up the environment with up
to 1,024 bytes (that's hex 400) after booting with ENVXPAND.

MEMORY DOCUMENTATION
====================
VERSION 1.01 8 NOV 1982 (C) MICROLIFE, INC. (301) 799-5509
Memory is a utility to allow dynamic setting/resetting of the amount
of memory used by DOS. The major advantage is that the system switches
can be set to anything your heart desires, with the knowledge that you
should not have to open up the PC to set switches while using MEMORY.
For example, some games (like ZORK and Adventure) seem to require a
maximum of 320K, the switches can be set for the 128K and then MEMORY
can be run to set DOS for larger amounts or smaller amounts of memory
as required. MEMORY can be used in batch files or simply run from the
system prompt to set DOS memory size from 64K (lowest switch setting)
up to 640K. More specific parameter information is as follows:
MEMORY Restores DOS memory size to what it was prior to
running MEMORY. Follow the example below:
Step 1 MEMORY 3 Sets DOS to 192K
Step 2 MEMORY 5 Sets DOS to 320K
Step 3 MEMORY Restores DOS to 192K
MEMORY 0 Forces DOS read the value of the switches on the
motherboard.
MEMORY N (Where N can be a decimal number from 1 to 10). Installs
N times 64K of memory to DOS. That is, assuming N was 7,
7 * 64K = 448K. A very important note here is that the
DOS can now be set to beyond the value of the switches
(544K Maximum) to 640K !!
An example of MEMORY used in an Autoexec file:
Commands Description of each command
.............................................................................
PWRUPCLK Sets the System time equal to the Quadboard time
MEMORY 9 Sets DOS memory size to 9 * 64K = 576K !!!
RAMDISK 10/A Creates a Ramdisk of size 10 * 32K = 320K
COPY *.* D: Copies all of Drive A: to Drive B:
D: Logs onto Drive D:
CHKDSK Checks the Disk Parameters
............................................................................
Special Notes:
1. MEMORY resets the system when run, except in the cases of bad para-
meters entered or when the same command is run more than once.
2. MEMORY will only install up to the available RAM present*I^ the system.
For example, you have 320K in the system, a command like MEMORY 6 would
result in an error and no change from the present memory size.
3. The QD Ramdisk software provided with the Quadboard reads the memory
size from the switches on the motherboard, not what DOS thinks it has.
By doing so, the maximum size of memory under the Ramdisk (reading
the switches) is 544K bytes.

title moreram 12-16-83 [12-16-83]
;-------------------------------------------------------------------------------
; MORERAM.COM - by Daniel M. O'Brien (v 1.0) 21 Dec 1983
;
; - freely adapted from a PC-WORLD User-to-User column program
; of the same name (object disassembled using ASMGEN) and from
; a program shown in a DR. DOBBS Journal article
; (Socha's 16 bit Toolkit) called MEMSIZE.
;
; This program has two (or three) purposes.
;
; 1) Allow a PC to use more memory than is allowed via the motherboard
; memory switches (544 K bytes for the 64K motherboard and 640 K bytes
; for the newer 256K motherboard). And because of 1)...
;
; 2) Allow faster power-up sequence by setting the motherboard memory
; switch settings to 64 K bytes installed.
;
; And as long as we are in the neighborhood...
;
; 3) Patch the ROM BIOS data area to indicate that this PC has four
; floppy diskettes installed (instead of the normal two). This is for
; ram disk emulation programs that require the motherboard equipment
; options switch to be set to include the number of ram disks.
; This is most notably required by the AST RESEARCH ramdisk program
; called SUPERDRV. This code is commented out. To use it you must
; uncomment out the code and reassemble. Search for the string:
;
; ;stub***
;
; Using MORERAM.
;
; First, copy MORERAM.COM to your boot device (floppy or fixed).
; Next, create or edit your AUTOEXEC.BAT file found on your
; boot device to include MORERAM as the **FIRST** program that
; will be executed. This is important as results are not guaranteed
; if MORERAM is not the first command executed at boot time.
; Next, open the covers of your PC and set the memory switches
; to indicate that your PC only has 64K.
;
; Now try rebooting your PC using the Alt-Ctrl-Del sequence.
;
; MORERAM will first display a hello banner and the amount of
; memory DOS thinks your PC has (should be 64K). Next, MORERAM
; will pause a second or two while it determines how much memory
; your PC really has. (It also clears this memory in the process
; to eliminate PARITY 2 errors later).
; Once the physical memory limit is determined, MORERAM will display
; that amount and then automatically re-boot. (Don't get excited,
; this won't loop indefinitely, because...) The next time MORERAM
; is again executed from your AUTOEXEC.BAT it will find that the amount
; of memory DOS thinks you have will be the same as that installed, and
; a reboot will be avoided!
;
; I use this program on my PC that has 576K (64K + 512K) worth of memory.
; Also, I have successfully tested it with 704K (64K + 512K + 128K) of memory,
; but this requires placing memory into the semi-forbidden zone (segment A000)
; designated by IBM as "reserved". But that's ok, as long as you don't install
; memory beyond this into the B000 segment where monochrome and graphics display
; memory live!
;
; Questions or comments should be left for me (DAN OBRIEN) on Gene Plantz'
; BBS in Chicago, IL (312-882-4227). I will attempt to fix bugs that may
; crop up, but I make no guarantees. You use this at your own risk (just like
; I do!). If you break something valuable, it's your own fault.

title moreram 12-16-83 [12-16-83]
;-------------------------------------------------------------------------------
; MORERAM.COM - by Daniel M. O'Brien (v 1.0) 21 Dec 1983
;
; - freely adapted from a PC-WORLD User-to-User column program
; of the same name (object disassembled using ASMGEN) and from
; a program shown in a DR. DOBBS Journal article
; (Socha's 16 bit Toolkit) called MEMSIZE.
;
; This program has two (or three) purposes.
;
; 1) Allow a PC to use more memory than is allowed via the motherboard
; memory switches (544 K bytes for the 64K motherboard and 640 K bytes
; for the newer 256K motherboard). And because of 1)...
;
; 2) Allow faster power-up sequence by setting the motherboard memory
; switch settings to 64 K bytes installed.
;
; And as long as we are in the neighborhood...
;
; 3) Patch the ROM BIOS data area to indicate that this PC has four
; floppy diskettes installed (instead of the normal two). This is for
; ram disk emulation programs that require the motherboard equipment
; options switch to be set to include the number of ram disks.
; This is most notably required by the AST RESEARCH ramdisk program
; called SUPERDRV. This code is commented out. To use it you must
; uncomment out the code and reassemble. Search for the string:
;
; ;stub***
;
; Using MORERAM.
;
; First, copy MORERAM.COM to your boot device (floppy or fixed).
; Next, create or edit your AUTOEXEC.BAT file found on your
; boot device to include MORERAM as the **FIRST** program that
; will be executed. This is important as results are not guaranteed
; if MORERAM is not the first command executed at boot time.
; Next, open the covers of your PC and set the memory switches
; to indicate that your PC only has 64K.
;
; Now try rebooting your PC using the Alt-Ctrl-Del sequence.
;
; MORERAM will first display a hello banner and the amount of
; memory DOS thinks your PC has (should be 64K). Next, MORERAM
; will pause a second or two while it determines how much memory
; your PC really has. (It also clears this memory in the process
; to eliminate PARITY 2 errors later).
; Once the physical memory limit is determined, MORERAM will display
; that amount and then automatically re-boot. (Don't get excited,
; this won't loop indefinitely, because...) The next time MORERAM
; is again executed from your AUTOEXEC.BAT it will find that the amount
; of memory DOS thinks you have will be the same as that installed, and
; a reboot will be avoided!
;
; I use this program on my PC that has 576K (64K + 512K) worth of memory.
; Also, I have successfully tested it with 704K (64K + 512K + 128K) of memory,
; but this requires placing memory into the semi-forbidden zone (segment A000)
; designated by IBM as "reserved". But that's ok, as long as you don't install
; memory beyond this into the B000 segment where monochrome and graphics display
; memory live!
;
; Questions or comments should be left for me (DAN OBRIEN) on Gene Plantz'
; BBS in Chicago, IL (312-882-4227). I will attempt to fix bugs that may
; crop up, but I make no guarantees. You use this at your own risk (just like
; I do!). If you break something valuable, it's your own fault.

QUIKUP.DOC
QUIcK power UP routines
Programs and documentation copyright 1983 by Herb Shear.
QUIKUP.COM is a short assembly language routine which meets the following
objectives:
1. Permit utilization a RAM in excess of the 544KB limit imposed by
the system board switches.
2. Permit fast power ups by allowing the system board switches to be
set to a low value.
3. Be compatible with AUTOEXEC.BAT for no hands booting.
4. No untested or potential parity error bytes.
To enjoy its features, employ the following steps:
1. Copy QUIKUP.COM to your DOS SYSTEM (boot) disk.
2. Make QUIKUP the first entry in the AUTOEXEC.BAT file.
3. Set the system board switches for a total memory of 64KB. You
may later have to increase this in order to run a certain class
of software that deserves no further mention.
4. Power up.
QUIKUPQD.COM is basically identical, with a slight modification so that it
will work in cooperation with Quadram's QM.EXE, QDXT.EXE and QMXT.EXE RAM
Drive programs (which just happen to be on this very same SVCS Club Disk
No. 43). [EDITOR'S NOTE: Not so on this SFpcUG Disk #106, however.] Note
that these three ramdrives do not check for a Quadram board (mighty nice of
them). Further note that the `XT' only implies DOS 2.0's 9 sector tracks,
and should not be construed as a restriction to XT hardware.
In the second step above make QUIKUPQD the first AUTOEXEC.BAT file
entry followed by the desired ramdrive. QUICKUPQD and Q* n/A will
work together to resolve the endless reboot dilemma.
REBOOT.DOC
We do not have complete doc. for REBOOT. It can be used to reboot the system
with software. See SETMEM.BAT.
If anyone has more info. Please get it into the HAL-PC library.
SETKEY.DOC
Documentation for SETKEY.EXE
SETKEY Version 2.00 (C)Copyright T A Davis, 1983
SETKEY is a program that lets the user redefine the keyboard. To use
this program, you must have DEVICE=ANSI.SYS in your configuration file
(CONFIG.SYS - ANSI.SYS is included on the DOS 2.00 system disk.) Both
ANSI.SYS and CONFIG.SYS must be present on the default drive when the
system is booted.
Use of setkey.
To use SETKEY, just type SETKEY |<filename> (the <filename> is optional.)
If <filename> is not specified, or if SETKEY cannot locate <filename>, it
will ask you for a filename to use. This file must be present in the
current directory of the specified drive.
If the file does not currently exist, SETKEY will ask if it should be
created. Reply 'Y' to create <filename>. If the file does exist,
SETKEY will use <filename> to redefine the keyboard.
If the file did not exist, SETKEY will ask you to press the key to
redefine. Then it will ask for the text to assign to the key. To end
this key definition process, enter ^Z (F6 or CTRL-Z) at the prompt for
'KEY ' You may include carriage returns in the text to assign to the key
by pressing [RETURN] and the program will display (C/R) and go on to
the next key. If you do not desire to include a carriage return in the
key definition, press ^Z (F6 or CTRL-Z) to indicate the end of the text for
the key.
After the key definition process is complete, the program will ask whether
you desire to re-define these keys now. Press Y to do so.
After you have created the a definition file, you may enter SETKEY <filename>
at any time to define the keyboard to the definitions contained in the file.
Further notes.
There is a limit of 128 characters that may be assigned to keys. SETKEY
will not allow the creation of a file containing more than 128 characters.
Instead, if you enter more than 128 characters, SETKEY will create a file
containing the definitions for all keys prior to the key definition which
exceeded 128 bytes.
You must end each line of text you enter as a definition with either a
space or a carriage return.
You may create as many definitions as you wish and re-define the keys
as often as you wish. If you get unexpected results, re-boot your system.
Unfortunately, DOS provides no way other than re-booting to un-re-define
the keyboard.

SETVAR.DOC
SETVAR -- Copyright (C) 1984 by Darryl E. Rubin
This program reads the standard input and assigns that value
to the environment variable named on the command line.
o If the named variable does not exist, it is created.
o If it does exist, it is deleted and recreated with the
new value
o The variable is not entered into the environment if
there isn't enough room for it and its value.
Example: echo test| setvar VAR ; same as SET VAR=test
On return to command.com, SETVAR sets the errorlevel equal
to the length of the string assigned to the variable
( 0 if the variable could not be created or assigned ). In
the above example, SETVAR returns an errorlevel of 4.
Note that SETVAR does not fold its command line argument
to upper case, so be careful! Saying SETVAR test creates
a different variable than "SETVAR TEST". The former
creates a variable "test" that cannot be accessed via the
DOS "SET" command ( SET folds its arguments to upper case ).
This can be particularly useful in batch files for multiple
responses and tests. i.e. this helps batch become a true
language.
The program was downloaded from the COMPUTER LANGUAGE
bulletin board in California.(MLM)
