- IMPORTANT INFORMATION:
- ======================
-
- To apply this patch, you need the following files:
-
- CMDPATCH.DBI
- CMDPATCH.BAT
- HOWTO.DOC (this instructions file).
- TEST.BAT (not necessary, but a useful demonstration).
-
- What this automated patch does is fix DOS 3.2's command
- processor COMMAND.COM so that, (a) the ECHO command will
- default to OFF when executing batch files; and, (b) the
- ECHO command in a batch file, followed by two or more blank
- spaces, will NOT be taken by DOS as an inquiry as to the
- status of ECHO, but as a line to be left blank in the batch
- file.
-
- Beginning with DOS 3.10, to leave a blank line in a batch
- file, you had to type the word ECHO, press the space bar
- one or more times, and then redirect the output message
- "ECHO is off" (or "ECHO is on") to the NULL character,
- thus:
-
- ECHO >NUL or ECHO > <Alt> 255
-
- Also, this patch will eliminate the need to make "ECHO OFF"
- and "CLS" your first two commands in a batch file if you
- don't want the contents of the file displayed on the screen.
-
- PLEASE NOTE that this patch has only been tried with PC-DOS
- 3.20's command processor. To our knowledge, it has not been
- tried with any other version of PC-DOS or of MS-DOS, and pro-
- bably would not work with any such other version. With ANY
- version of DOS (including PC-DOS 3.2), you use this patch at
- your own risk (although no problems have been reported with
- PC-DOS 3.20).
-
-
- HOW TO PROCEED:
- ==============
-
- 1) Format a new diskette with the /S option under PC-DOS 3.20.
- Make sure that COMMAND.COM has been copied to this new
- diskette. DON'T TRY TO DO THIS PATCHING IN YOUR ORIGINAL DOS
- 3.20 DISKETTE.
-
- 2) Copy DOS' DEBUG.COM to the new diskette.
-
- 3) Copy all four of the files contained in this set to the
- same diskette.
-
- 4) At the DOS prompt, type CMDPATCH to execute the file
- CMDPATCH.BAT. The patching will be done automatically,
- with DEBUG getting its input from CMDPATCH.DBI instead
- of from the keyboard.
-
- 5) If you have a booting hard disk, DON'T copy the patched
- COMMAND.COM to the hard disk until you have tried it
- thoroughly on the new floppy diskette. In any event, make
- sure to keep at least one copy of the original, UNPATCHED
- COMMAND.COM.
