What about "MDBODY nti" for example?
You could implement this platform-independent, as you already have done
implementing the directory character, e.g. ":" on a Mac, "/" on Unix, "\" on
Windows.

....see above...

SOME people might do it this way, I would force all files to lowercase when
moving them to a UNIX platform, so the problem WOULD not occur (I have to
use lowercase characters in every ORIGIN and INCLUDE as well, of course!)

What if I save the file as demo.BET on Windows, include it in a BETA program
via "INCLUDE 'demo'" and store it on the UNIX machine as "demo.BET" or -
"demo.BeT" or something like that.
Will it work?


BTW has someone tested my RAS implementation for BETA on a Windows NT or
WIndows 2000 machine?
I would be interested to know if it works there!
