Thanks Craig. That is just what I was looking for. Running the program
at the main level is not a problem for me. Basically, I have a bunch of
data stored in array's and saved in an IDL save file. I just needed
something to convienently get them out of IDL and into individual text
files, while retaining the information contained in the array names.
