Ken,

There was recently announced on the net a patch for Word* that would let
it look to User 0 for its overlays.  Unfortunately, the patch did not
work on my system for some reason (I haven't had time to really figure
out why).  I have no direct solution either, and commonly use DUPUSR
(a utility that puts the NAME of a desired utility/application into a
User Area, plus pointers to the main source (in User 0), yet does not take
up any actual disk space!  (Except for the directory entry, of course.)

One hazard:  You'd need to carefully caution users of those other User Areas
NOT, repeat, NOT to carelessly erase that DUPUSR'ed file.  It demands a
CTRL C immediately after erasing (e.g., before any disk writes, I believe
is the critical parameter), else it will do a JOB on the entire hard disk
directory!!!

But it is a fix.  I've patched CP/M to look to A0> for all my other
applications, and DUPUSR the overlays to User Areas as needed/desired.

Good luck, and regards.
