Max, Please clip off the unwanted parts of the message.

OK to fair. ;) It was file level password protection and required the
whole colume to be enabled for it. Security level was low though. If the
user could assemble and run a program they could write code to access the
disk directory and toggle the right bits and they had control. It was
aimed at captive applications where the user had limited resources and
could not get directly at the file system. Many of the things in CPM3
are there to provice more direct compatability with MP/M.

As to weird, no most of the additions they did were similar to the ZCPR
groups and other were doing in parallel and had sound basis.
