Being completely new to OOP myself, this seemed to me more
common sense than madness. :-)
Perhaps IDL *could* know that classdata1 is a local variable,
but IDL objects are implemented as IDL structure variables.
Without completely creating a new variable type in IDL,
which I presume would have taken longer than RSI wanted to
take, this seems a sensible and straightforward approach.
Cheers,
David
