Ah, I knew I should have put two in that box. :-)

EXTRAC!! Boy that takes me back. And looking at the on-line
help I see it was first written for PDP-11 computers.
There can't be even half a dozen people left at NASA
who remember those days. (Well, in addition to Wayne Landsman
and Joe Gurman, I mean.)

Indexing, believe me, is more art than science. Even
the paltry excuse for an index in my book took me well
over a week of work. Technical writers for computer
software companies often have the interest in developing
good indexes, but they are rarely given enough time to
do it properly, since it is usually the documentation
printing schedule that is holding up the software release.

In any case, this is one of those topics that is hard to
categorize, even if you have a lot of experience in IDL.
But if you read the on-line help for EXTRAC, however, you
were close. Prominently featured there is "Subscript
Ranges", which is pretty much what you were looking for.

Cheers,

David
