Re: Using Spawn in Win2K

["Dave Head" <headdp@nswc.navy.mil>]

Further info...  I _found_ command.com under c:\winnt\system32.  Why wasn't
it found in the search starting at c:\?  I dunno - prolly misspelt it.  But,
I put the whole path into the spawn for the command. Same result.  So, not
only don't I know how to get it working, I've got nary a clue as to why it
doesn't.

Please help.
