Nigel,
Thanks for the tip. I changed it and it originally took about 260% of the
CPU. I ran the CRTJVAPGM command again and it took around 10 again.

I appreciate the help from everyone on this. I don't really have a need yet
for it, so I have time to play with it and attempt to have it run a little
better.

I think I need to look at the whole thing again anyway. I just ran it on my
PC and it was taking about 50% of the CPU.

Looks like it's time for me to start learning how to optimize Java.

If you have a tight loop, you MUST call Thread.yield() or Thread.sleep() to release the CPU. I would suggest the sleep().
