I think I have the answer for you . There's a translator to convert Turbo 
Pascal to Quick C written by Glockenspiel. It's in the public domain 
(sponsored by Microsoft to get people to use C, I guess. You have to
write your own copies of the library routines, e.g. to handle sets, but
it's not that hard. (Mail me for mine if you like.) You can get it in
the UK from the Lancaster Public Domain Library. The address is:

uk.ac.lancs.pdsoft

You do cpf (I think you yanks call this ftp) with user=pdsoft,
password=pdsoft.

There is a file called /micros/ibmpc/index, which lists the collection.
What you want is /micros/ibmpc/e211/e211t2c.boo, which contains the
translator + documentation.

The thing works OK. There a some bits that need to be commented out and
then translated by hand (complex IF-THENS, etc.). The only thing it gets
wrong is a DO...USING nested inside another which uses the same type of
pointer - the same pointer is used for outer and inner loops.

I translated 5000+ lines of a genetic analysis program with this and
compiled it on a few different machines. It was much quicker and easier
than using the Pascal compilers on the original code. Good luck with
this, I'd be interested to hear how you fare.

Pascal?                               Just say no.
