PC Magazine had a good sample program called DOSTERM that covered all the necessary functions (except interrupt driven output, which isn't essential). I believe it was Vol 8, No. 16 and can be found on Simtel. It's commented assembler source code that helped me quite a bit. -Sanjay Aiyagari (hd7x@vax5.cit.cornell.edu)
