The MS-DOS COMMAND.COM shell uses the forward slash '/'
as its SWITCHAR to designate command-line parameters.
In dos versions 2.x the following line could be added
to the CONFIG.SYS file to change that character to a '-',
allowing the '/' to be used as a separator for directory
names in a path:
SWITCHAR=-
This doesn't work for dos 3.1. Is there another way to do it?

Looks like quite a few characters were lost in that posting; it may have come about because the "debug script" I included in the original article had CR codes without LF codes following -- that's the way Debug insists its input be formatted. I've used the changed "command.com" on several IBM PC/XTs and a foreign clone ("Standard Brand") with no side effects whatever. Errorlevel works fine. I use "Keydo" instead of CED but no trouble there, either. Here's the complete change to type in by hand: debug command.com -e 105b 2 -e 1967 0 -w -q and here's the "debug script" I posted in the original article. THEY SHOULD BE THE SAME. If they are not, best do it by hand (if you do it at all). It would be a pity if we can't post "debug scripts" to the net and have them arrive whole ... The command: debug command.com < fixcom The contents of the file "fixcom" (remove dashed lines above & below) ---------------------------------------------------------------------- e 105b 2 e 1967 0 w q ---------------------------------------------------------------------- Of course, the problem may be with the PC clone this was tried on ... -- Ed Nather Astronomy Dept, U of Texas @ Austin {allegra,ihnp4}!{noao,ut-sally}!utastro!nather nather@astro.AS.UTEXAS.EDU
