FreeDOS:
C:\>truename EMMXXXX0
C:/EMMXXXX0 

C:\>ver
FreeCom version 0.83 Beta 32 [Dec 03 2001]

I used the "command.com" from the latest FreeDOS "base1" install disk from 
their server.
The "comcom.com" which came with DOSEMU and all the tools based on 
"generic.com" make my dosemu go into an endless loop or simply quit. They 
work on a friend's computer without problems and I haven't investigated in 
this further yet.

MS-DOS:
C:\>truename EMMXXXX0
C:/EMMXXXX0 

C:\>ver
MS-DOS Version 6.22

Ok.

By the way, that program gives me a headache. It even breaks with MS-DOS under 
vmware. With another error, of course.
