Structure Creation with Execute [message #3992]

I am reading in an HDF file containing 30-40 Scientific Data Sets of
varying size and rank. The sizes are not known ahead of time.
I would like to read each data set into an element of an anonymous
structure and output that from the function. Currently I construct
a structure definition string by going through the HDF file and
collecting the dimensions of each SDS. I then execute it, to define
the structure (with tag names HDF0, HDF1, ...), and then make another
pass through the file to read the data into the structure.

This works well if there are only a few data sets in the file, but
if the structure definition string exceeds 131 characters (IDL's
ridiculously-low maximum for an EXECUTE), the EXECUTE fails.
Is there a way around this somehow? Is it possible to append one
structure to another (I thought not)? Any suggestions?
