You are indeed prescient, David, since my version of the functionality on
the codebank
is named "OBJECT_HASMETHOD". Of course, in spending weeks plowing through
the source code of the iTools, as you've probably done, you probably
subliminally noted
its use therein.

I don't think it ships with IDL, but instead it was found on the RSI
contrib site, contributed by Jim Pendelton. You even remarked:
http://groups-beta.google.com/group/comp.lang.idl-pvwave/msg /1c08f8398539fcd6
Maybe you need to make that webpage after all ;). Or you could just do:
http://groups-beta.google.com/groups?as_q=object_hasmethod&a mp;as_ugroup=*idl-pvwave*
