Note to self: Any time you say "The only way" in this newsgroup, you're
bound to be wrong.

David's web page correctly points out that copies of an anonymous
structure are equivalent, and thus can be concatenated, e.g.

IDL> record = {a:0, b:'name', c:{d:0, e:0}}
IDL> a = record
IDL> b = record
IDL> c = [a, b]

Cheers,
Liam.
