Variables in IDL 4.0.1 can have up to 128 letters. I suppose two
variables could be unique with up to 127 letters. In earlier
versions of IDL, variable names could be long, but only the
first 15 letters were significant and used to distinguish
between two different variables.

I don't know. I don't have reasons to suspect so, but I don't, as
a rule, use longish names in structures. I try to use *short*
names. :-)
Cheers!
