MERGEFILE v1.15 & v2.15 INCOMPAT.DOC 4/20/94
There are no known incompatibilities at this time, but there could be. I
can only test IBM PC-DOS 2.1 and MS-DOS 3.3 and 5.0. MergeFile v1.?? runs
fine on all, and v2.?? did, but I started using a unit from a programmers
tool kit in version v2.14 that caused the computer to lock up with DOS 2.1
(there were no problems with 3.3 and 5.0). An initialization routine that
checks for an installed mouse was the reason. The interrupt and function
being used were documented for DOS 2.1 according to my DOS reference, but
apparently for my PC-DOS, it didn't work. I altered the code to not do a
mouse check on DOS versions below 3, and now v2.?? works fine on DOS 2.1,
but I can't guarantee it will run on version 3.? below 3.3, or on another
version of 2.?.
