reading compressed files [message #46942]

Hi

I have to read compressed files with IDL. As I can not read the files using
the compress keyword (I don't know why, but if I open the file using the
compress keyword I do not get what I expect) I spawn a winzip command, unzip
the file first and read it in with the normal IDL commands. In principal
everything works fine, at least if the compressed file is not corrupted,
i.e. winzip can not extract the content of the archive because of some
missing blocks. As I have to read thousands of files I wonder if there is a
simple way to check if a compressed file is ok.
