My bet is that you aren't running into # of record limit so much as a SIZE of
record limit...

If they are 2 byte integers, you'd be OK...but if 4 byte integers, reals, or
otherwise declared, you'd be over the 32767 byte/record limit.

Try declaring the arrays to be integer*2. Recompile and call me if I can
help in any other way.
