Ok, my *one* cent worth.....
I had this same problem in pascal yrs ago, i solved it with pascal's
blockread() and wrote my own text parser. Then i found some bug i have
since forgotten in the keybd read routine, and began bypassing dos for that
too. Then i *needed* some binary file routines for text files, and darn it, had
to goto assy routines for that too, to move the dos file pointer around. Or
was it the other way around? Well, that's why this is only one cent, Jiri.

Anyhow, use dos int21, function 14 and 15 to solve most problems. Are
these covered in dos32lib, David?
