1. DISTRIBUTION NOTICE
----------------------

This software may be distributed freely, provided that this text file, and
the executable code are included together and remain unchanged.


2. DISCLAIMER
-------------

I make no representations or warranties with respect to this product, and
specifically disclaim any implied warranties of merchantability or fitness
for any particular purpose. In no event shall I be liable for any loss of
profit or any other commercial damage, including but not limited to special, 
incidental, consequential or other damages.


3. INSTALLATION
---------------

1. After running COMMEM.EXE, you should have the following files:
 
   RCCOMMEM.EXP - Command memory tee display driver.
   README.TXT   - This file.

2. Copy RCCOMMEM.EXP to your AutoCAD driver directory. For Release 12 this
   will be something like C:\ACAD\DRV, for Release 13 it will be something
   like C:\ACADR13\DOS\DRV.

3. Edit the file that sets up your AutoCAD environment variables. If you
   are using the default batch files that AutoCAD creates, then it will be
   ACADR12.BAT for Release 12, and ACADR13.BAT for Release 13.

   Add the following line, where YOURDRIVER.EXP is the full path name of your
   current display driver file.

   SET RCPADIT=YOURDRIVER.EXP

   If you are using the supplied VGA driver for Release 12, and your driver
   directory is C:\ACAD\DRV, then the line should look like the following:

   SET RCPADIT=C:\ACAD\DRV\RCPSVADI.EXP

   If you are using the supplied VGA driver for Release 13, and your driver
   directory is C:\ACAD\DRV, then the line should look like the following:

   SET RCPADIT=C:\ACADR13\DOS\DRV\RCPDLX.EXP

4. Start AutoCAD with the -r switch to go directly into configuration.

   Example: ACADR12 -r

5. Select Video Display.

6. Choose the COMMANDMEM 1.0 driver.

7. Configuration will continue as normal for the display driver that you
   specified with the RCPADIT environment variable.

COMMANDMEM will be active the next time you enter a drawing.


4. USAGE
--------

COMMANDMEM works by remembering anything that is entered immediately
following AutoCAD's Command: prompt. Anytime a command is being asked
for, even if you have already started to type a command in, you may
press the left or right bracket keys to scroll up and down through
the command memory. When a command is retrieved, it is display at the
Command prompt just as if you had typed it in. At this point you may
backup over the command, add characters to the command, press the left
or right bracket to scroll again, or press ENTER or the SPACEBAR to
execute the command.  Following is a sample editing session (Anything
inside {braces} is what you would type):

Command: {LINE}

Command: {CIRCLE}

Command: {ERASE}

Command: {[}

Command: ERASE{[}
 
Command: CIRCLE{[}

Command: LINE{]}

Command: CIRCLE{[}

Command: LINE{]}

Command: (Back to blank command prompt){]}

Command: LINE{]}

Command: CIRCLE


5. LIMITATIONS
--------------

- Works with Release 12 and 13 DOS versions only.

- Does not work while the display is "flipped" to a full text screen, or
  "pop-up" text screen.

- Remembers all commands typed at command prompt, including invalid ones.

- Maximum command entries is preset to 5.

- Will only remember the parenthesis and function name at the beginning of
  lisp expressions. For example, '(load "file")' will only be recalled as
  '(load'
