Simple question regarding CATCH,/CANCEL [message #72670]

Hello,

I use CATCH error handling in just about all of my IDL procedures/functions.

If no error occurs, do I need a
CATCH, /CANCEL
at the end of the pro/func? Or does exiting the pro/func cancel the error handling that was established on entry
automatically?

The documentation doesn't explicit state what happens, although the example does *not* have a "CATCH,/CANCEL" before the
END (I also recall reading a post on this newsgroup stating that it was not necessary to CANCEL and error handler for
normal termination).

Thanks,

paulv
