Actually, the entire problem surrounded a missing comma in the
embedded string data...  I need a program that checks the integrity
(syntax) of String_Arrays/String_Tables in 'C'....

Dear DJGPP Developers:
Please add the feature to be able to 'force' Cwsdpmi/etc support!
This would prove useful for easily comparing behavior between 'DOS'
and 'Windoze' environments, without the enormous inconvenience of
having to boot-in-and-out of Windoze.
Fortunately, I have a 486 nearby which I can network under ms-dos,
so I had a way to quickly compile on the P4, and send it immediately
to the 486 for testing until I discovered the problem.

I did look into GDB, and printed the RefCard.pdf, but haven't actually
given it a serious try yet.
I discovered that my Coding is sound enough, I just left out a comma in
String Data used by the program... :-)

Finally, how nice it is to see people using 4DOS!
Which, as I understand it, is no longer supported for DOS <cowards>.
