Hi Randall--

Array subscripting is so fundamental to the IDL language (at least
*these* days it is :-), that it's just something that must be learned.

A similar question might be a person who wants to add two variables.
We all know that you just do "A + B", but when you try to look up ADD
or PLUS or ARITHMETIC in the index, there's nothing relevant there in
the index. Drat. Ahh, but if you happen to know to look under
"operators/addition" then there is no problem. Eureka!

The moral to this story is, if you know what you are looking for then
you will find it! [ There is an entry under "Array Subscripts" ].

Craig

P.S. I agree with David that indices are hard to produce, but the
on-line IDL one is not *so* bad. For a long time it was impossible to
find the codes for FORMAT strings using the index, but now it's much
easier.
