Subject: Protection schemes

Sometimes people come across copy protection, and I wanted to share a simple
method of keeping the disk catalogue non-viewable on dfs disks. It involved
using in
the title block of the catalogue sectors characters which were out of the
viewable 
range, specifically ASCII zero. I once copied the catalog block to another
location,
re-wrote the block, and put it back.  Then the catalog was visible.

What other protection schemes were in use?

cheers,
Rick
