- TITLE : CLEAR SCREEN COMMAND PATCH

-
-
- This patch solves the problem you are experiencing with the CLS
- command in DOS, version 3.10. The problem is a result of the
- interrupt (20H) used by DOS to determine if ANSI.SYS has been
- installed. To modify this situation, you will need to patch
- COMMAND.COM using DEBUG as follows:
-
- Use the DOS utility, DEBUG, to apply the following patch to a
- copy of your original COMMAND.COM file. Copy DEBUG.COM into the
- directory (or onto the diskette) where your working copy of
- COMMAND.COM is located. At the DOS prompt, type the following
- information exactly as it appears. (Conclude each line by
- pressing <Enter>.)
-
- Note:
- 1. DEBUG is not sensitive to upper and lower case. All
- addresses are listed in upper case for ease of readability.
-
- 2. While in DEBUG, the prompt will appear as a dash (-).
-
- 3. If you do not receive the appropriate response, press "q"
- followed by <Enter>, to quit. Check your version numbers
- and, if correct,try again.
