I'm not trying to be facetious when I suggest using something other than an IDL save file
for storing output. Say, netCDF? Or maybe Liam Gumley's binary data I/O tools for IDL. See

http://cimss.ssec.wisc.edu/~gumley/binarytools.html)

While I can't help you with your current dilemma, Craig Markwardt has posted about his
tools to interrogate IDL save files. See

good luck
