I'm trying to devise a way of dealing with a bunch of data items which will
consist of a fixed number of header fields and a widely varying number of data
entries. For one such item, an anonymous structure seems appropriate, but I
don't see how I can generalize this to an array.
If I define an array of structures based on the largest array (which I won't
know ahead of time anyway), I'll waste a huge amount of memory.
I thought of building an array of pointers to anonymous structures, but the
structures seem too anonymous for this to work.
Since I will be pulling the data from a large database, I could write the data
to a file, and let the processing programs read the file and define structures
on the fly, but this seems pretty inefficient.
Any better ideas would be greatly appreciated.
Thanks,

PS: I'm bi - it needs to work with both IDL and PV-Wave
