     Oh, do I know that!  I got my degree recently after many years in
the industry.  Some of my classmates had very weird ideas about how
computers and the industry work.

     *** You are doing exactly what I want.  Thank you. ***

     At some point, I am going to have something that works.  I hope
then it will get the evil eyeball from people.  ("Oh, you shouldn't
have.")  e.g. I found out today that, rather than using escape(), I
should use encodeURIComponent().  At this point, I would not have
figured that out myself.

     Many corrections are easy once one knows that a correction needs
to be made.

Sincerely,

Gene Wirchenko
