Whoops! Sorry, had those in there because they are a
whole lot more useful than the real error handlers
during debugging. Gone now. :-)

No, they are easy. The only difficulty is knowing
how to write them without common blocks. But you have
my book, so I'm *certain* you know how to do that! :-)

P.S. The biggest mistake most people make when starting
out to write compound widgets is to use the programs
supplied with IDL as examples. *Those* will get you
lost, for sure. :^)
