The following is a fix for the COMMAND.COM supplied with PC-DOS 3.00
on the IBM PC/AT. This version of COMMAND.COM does not correctly scan
multiple environment variable references (such as %PROMPT%) in a
single line of a .BAT file. Following is a sequence of DEBUG commands
which, when applied to COMMAND.COM will fix this problem. It also
changes the word "DOS" in the DOS signon line to "dos" so people will
know it's been patched.
Make sure your copy of COMMAND.COM has the size, date, and time shown
here. If not, DO NOT USE THIS PATCH!!!!
