Thank for the help, it worked very well, although I did decide to
change it to look like 1(12) instead of 1/12 (it was treating the
latter as a date). But, the quotes and the pound sign worked like a
charm!

Also, I looked over where you converted my code over to OO, and I can
sort of follow what's happening, but, not well enough to expand the
program any further (it's probably only about half written). So, I'll
keep what you've done as a reference, but, I'm going to continue to
write it in a procedural style, until it's "done-done". Then I can
decide if I have the extra time to invest in trying to grok OO style.
