I fail to see how this "feature" could be used. If you call a function
as
value = FUNCTION(args)
and FUNCTION() returns an <UNDEFINED>, this will cause an error.

Of course, I'm not using my imagination enough. If you have a
procedure, and you're not feeling like using any normal error-handling
mechanism, you can simply define it as a function and execute it using
HELP, and use a HELP-parsing routine to determine if it ran correctly
or not. Is there an obfuscated IDL contest?
