I am new to this "turbo" thing, but I have some code that was developed
elsewhere using Turbo Pascal 4.0 and I would like to use these procedures
and functions as they are, if possible. It's kind of a long story why, but
I NEED to be able to link them in with a C-language program, and call them
(as externals) from the C program. Going the other way (which I can do, by
the way) won't work. But Turbo Pascal, as far as I can tell, can't create
a regular old .OBJ file! I can create a .EXE file, which I can then turn
back to a .OBJ file with 'BINOBJ', but I need to have a separate one for
EACH external procedure. That won't do either!

I used to program with the Microsoft Pascal Compiler, and I THINK I remember
(this was a while ago) that you could label a procedure or function as
"Public", for use by other modules. In Turbo, they have circumvented all of
that with this weird "Unit" stuff, and the .TPU files. It LOOKS like the 
.TPU file is what the old .OBJ file was, the "Interface" section corresponds
to declaring the procedures as "public", and the "uses" is like saying that
these things are "extrn". BUT now, because of this (proprietary??) format,
I can't call the sub-routines from another language.

Anyone have a solution to this? I'm afraid I'm in a bit of a hurry here, but
I AM stuck.

Thanks LOADS!
