HASH question [message #75367]

Hi all,

I have a bunch of information which I'd like to store in an organized
fashion:
~IDs of some stars
~Stellar types
~Magnitudes and fluxes in different images

One way I could store the information would be as an array of
structures, with each element being a single star, but I don't a
priori know how many stars I have, and to find a particular star I'd
have to search on the ID element. So, I could use a HASH of
structures so I could index by ID, which would be ideal, but then
assigning values to the individual tags of the structures is much more
complicated. I could instead have a bunch of hashes, one for each type
of information, but that would get pretty unwieldy.

So, IDL gurus, anyone have a suggestion for how to organize this most
efficiently and elegantly? Thanks!
