Problem running NEC4

  OFFICE MEMO Problem running NEC4 Date: 9/1/95

I have been running an antenna calculation using NEC 4 on a486 33 MHz PC with
8 Meg of RAM and about 17 Meg hard drive space. NEC creates a Tape11.nec file
and writes to this file once the memeory is full. The problem is that this
file gets larger than the hard disk space available which causes a message to
come up stating that there is a serious disk error. This problem was not
evident on machines that had more memory or on another machine which has
slightly less memory. Updating DOS from 5.0 to 6.0 did not solve the
problem, changing the STACKS command in the Config.sys file to free up more
memory did not fix problem. When more space was cleared on the hard drive
(28Meg total) the large file that the computer was previously unable to run
worked without incident. However, the run took 3.5 hours, whereas a 486
66MHzwith 8 Meg RAM ran the problem in approximately 1 hour. Additionally,
when running smaller files in a batch mode the run blows up because the size
of the tape11 file gets larger after each run. Yet after a successful single
run tape11.nec has been deleted. This occurs even after delete tape11.nec
lines are inserted between each NEC run.
Why does NEC need to create a file so large?
Is there any way to reduce the size of the created file?
Is the problem in the way that the machine accesses memory?
Why wouldn't the tape11.NEC file be deleted after each successful run inside
the batch run?
