Say what!? I don't think so. :-)
Did you save the routine my_class__define? I think
you are not running the object definition code (or
INIT code) you think you are. After starting a fresh
IDL session, restore your files, create your object.
Now, type: Help, /Source
Is the MY_CLASS::INIT function the one you think
you are *suppose* to be using?
Cheers,
David
