Deleting named structure variables isn't impossible. Changing
the definition of named structures is impossible in
that IDL session. But in any case, it doesn't look like
you are creating named structures. It looks to me like
you are creating anonymous structures. :-)

P.S. I had occasion to work with French programmers last
week and this discussion reminds me of that. Very fast,
very unfocussed, throw enough lead out there and you
are sure to hit something! Whew! Maybe I'm just getting
old, but I still like to think a few minutes before my
fingers start moving. :-)
