about blobs...
Thanks, that was all very well explained. (And no, my head didn't explode... although I agree, there may have been a few too many blobs.)
I'm actually a mathematician, so the idea of expressions is old hat to me. You all explained it very well. Thanks for the link to that thread -- I'll check it out later if I need more assistance when I get started on my next book.
Thanks for all the help (and the laughs). I can't wait to get to work today and try it out. (which reminds me... I'm late already!)
