Chris,

Thanks for this post. I've been looking for a way to do this on gzipped datasets for a long time. The only thing I've found prior was this, but it requires writing out the compressed dataset from SAS. You can't do the gzip command from unix command line, which is common practice.

I've tried your macro above, and while it does list the compressed files in the directory, unfortunately, it does not list the contents in the _Contents1 dataset. There are 0 obs. I have seen your Filename ZIP blog post as well. Hopefully, I can get this working. I would love to leave my very large datasets compressed (350GB+ uncompressed, <70GB compressed).

I'm using 9.4 M4. Any thoughts?

Regards,
Cory Vandenberg
