That will allow transparent reading of gzip files. A gzip file is not
an archive, as the file can only hold a single uncompressed file. zip
files (or tar archive with external compression: .tar.gz, .tar.bz2)
will hold a larger number of files. It is this latter capability the
OP is after. Without shell supprt, I don't think IDL can do this out
of the box. The code would be platform dependent (it would not be too
bad on *nix, I can't comment on running it on Windows).
