Protect               NAME, RECURSE/S, SET=+/K, CLEAR=-/K

The Protect command allows you to modify the  Protection Bits  of the
selected files and directories in the active directory window.  When you
select directories, you are asked whether you also wish the files within
them to be protected.  For each entry, you are presented with a requester
displaying the protection bits currently set for that entry.

If any directories are selected to protect, the  Recursive Filter  may be
used to determine which files will be affected.

This command applies to all selected files in all the current  SRCE 
listers.
