I'll just point out one other thing for the article you
are writing. The nice thing about arrays of structures
is that you can easily pull vectors out of the structure
fields.

So, in the example yesterday, if you wanted a vector
of all the "int_1" values in the third "unit" in the
file, you can do this:

IDL> d = unpackData(data[2])
IDL> help, d
D STRUCT = -> <Anonymous> Array[5]
IDL> vector = Reform(d.int_1[*])
IDL> print, vector
1 2 3 4 5

Cheers,

David
