This probably means that you call some DOS or BIOS function too
often.  Can you identify that function and explain why do you need to
call it that much?

One thing that v2.02 changes is the way buffered file I/O works.
v2.02 adapts itself better to the specific use of buffered I/O
functions (sequential vs. random access), which should show in
programs that seek into files a lot.  Perhaps your program is one of
those?
