Subject: Why won't CPM Plus work?

There seems to be a bit more concern than warranted about programs
running under 2.2 being easily transportable to CP/M-Plus (aka 3.0.)
It is my understanding that as long as a program does not use BIOS
calls for disk operations, there should be no problem. A fellow at
Digital research has assured us that >95% of the programs he has tried
have given no problems. Those like DU, which uses BIOS calls rather
than BDOS calls will not work, but ths class of program is certainly
in the minority.
