A friend is looking into buying a new system. He has the option of getting C/PM 2.2 or 3.0. He has been told that 3.0 is completely upward compatible with 2.2, but I seem to remember messages here that indicated some software will run on 2.2 but not on 3.0. Does anyone else remember the discussions or have some clarifying information of this controversy? Also, does anyone know of a C/PM users group located in the South Bay area of Los Angeles, California? I know of the Xerox Users' Group, which is primarily oriented around the Xerox 820, but since this is a C/PM machine, it sort of qualifies. This users' group is, however, limited to Xerox employees and family members. Are there any others? Cheryl

From: Sam Hahn <Samuel@SU-SCORE.ARPA> I've had 3.0 running since March, and have had NO problems with the software that I own. All of it trundled over to 3.0 with nary a sneeze. One thing to be careful of is that xfcb (extended file control blocks) will not appear correctly to 2.2 if you take a 3.0 disk and try to read it under 2.2. That's ok, though, because you can turn xfcb-making on or off, or even delete xfcb's. Another thing to watch out for is fancy shell-programs that assume the ccp does what it does in 2.2. (Since I own no fancy shell-programs, I guess my first paragraph isn't as strong as it might appear). -- sam -------
