I think you are thinking of the ratio for random ASCII display > characters. Typical compressed books etc. have a huge ratio of about 30:1 They do not, unless the source representation is extremely bloated. I just did a couple of tests with large, highly-redundant ASCII documents (the Perl 5 change log, for example) and gzip -9 just to confirm, and didn't see anything better than about 5:1. If you believe otherwise, cite a source. -- Michael Wojcik michael.wojcik@microfocus.com He smiled and let his gaze fall to hers, so that her cheek began to glow.
