Thanks to several folks for replying to my recent request for help
with a large global array.  I asked generally (and got a general answer).
[In fact, there is nothing in FAQ about this, and maybe it is not a
FAQ, but anyway I got some interesting and useful advice from various
people that I would be willing to assemble for the FAQ keeper -- e.g.,
that many C-library functions won't work on huge arrays]

Meanwhile...back to my problem...
Now I will ask specifically, by showing what I am trying to do, and
see if I can come any farther than crashing my system.  Sometimes the 
following code seems to work, sometimes it doesn't.  Once I ran it inside
of tc's debugger, and got an "internal error, please report to Borland"
My honor does not lie in my C programming performance, fire away!

Thanks,
