I don't know how many people are so interested in the guts of IDL save
files that they'd read Craig's documents on them, but I'm just crazy
enough to take a look.

Anyway, I'm trying to understand a little better how things are arranged
in a save file. Maybe if I give the document a little more time to
digest I'd have my "Aha!" moment of understanding where all becomes clear.

What I'm interested in is an example of a save file which consists of a
structure with multiple one-dimensional arrays. The arrays are the same
size, but may be of different primitive data types (usually integers,
sometimes floats, sometimes strings). I guess I'm trying to figure out
how all the records line up and where everything falls for a complicated
structure like this. I want to determine how easy it would be to create
a save file such as this outside of IDL.

By the way, do you (Craig) have plans to update the document for IDL 6.0?
