Now here is a project for ITTVIS. If they would incorporate
widgets into an object system with "messages" I would *definitely*
spring for the new IDL version. That would be something worth
having. And, no doubt, their iTools would even be a little more
comprehensible. :-)

Does your ERROR method provide a way of getting a traceback?
That was my biggest problem with error methods. Sure, I could
record and report the error, I just couldn't figure out where
it was to fix the darn thing!!
