It won't. Microsoft C is quite incompatible with TP (IMHO) unless something has
changed, which I doubt. It seems there's some kind of headers and things at the
assembly end that aren't allowed by TP with the $L statement. Sorry about being
vague about this - I don't have the facts to hand - just trust me - they don't
fit together.

However, all is not lost. There is something you can do if you have the source,
with a small amount of tweaking, there is a chance they will compiler in Turbo
C. I understand that Borland have improved the interface between TP6 and TPC -
there were severe restrictions with TP5.0 (and 5.5 I think, although I never had
that version). 

I've yet to try this out, although I have tried out TP5.0 and TPC. And the latter
can do some useful things. However, a big caveat - unless you have the run-time
libraries source for the C libraries, you cann't use C library calls, you can
use the pascal equivalents. Sound complicated - it is, so only worth doing if the
C code is really useful.

The other option is to convert the C code to pascal. There is a C to Pascal 
program available. I have also written a rather elementary sed script to do
the donkey work of the simple lexical translation ({ to begin, = to :=, == to =,
etc.) If the net is interested, I'll post it - it's not very big (nor, incedent-
ally is it complete).

You're welcome, if this _was_ any use.
