Can someone please give me a complete description on how you link Turbo C modules with TASM modules?  I keep getting "Undefined symbol" messages in Turbo C (I'm trying to link a TASM module into my Turbo C program).

Are you getting a large number of UNDEFINED SYMBOL messages?
Would you give an example of the message that you receive as well as the function that you intend to call?
It is probably a matter of ornamentation or case.

I am getting ready to go home, so I thought that I would dump all the various possibilities that I could think of and let you see what is what.
Is the assembly module of your own creation:
   do you have underscores in front of any external labels?
   are you assembling with the /ml switch to preserve case?
In the function prototype, do you declare it 'extern "C" '?
If the librariy is not of your creation, and a quick look with a binary editor shows that the functions are all in upper case, you can either swtich your function names (prefereable) or set the linker to be case insensitive.

Perfect... it works fine now.  I wasn't using the /ml option on TASM.  Thanks a lot. :)
