6.22 I'm trying to compress some IMAGE databases using LZW, but they won't compress even though the group, account and user all have PM capability.

To process IMAGE databases, the LZW program must be given PM (the standard distribution does not have PM for security reasons). You can use LINKEDIT as follows:

:linkedit
