MS-DOS 6.0
MS-DOS 6.0 apparently does something different in the new
version of EMM386.EXE. The command NOEMS acts differently than the
command in version 5.
The Microsoft MS-DOS 6 upgrade manual suggests, (in an odd
place), on page 166 that you change the NOEMS statement to RAM.
MEMORY PROBLEMS:
CALLSIGN.EXE is written and compiled with Clipper.
Clipper contains an built in virtual memory manager which allows
a program larger than 640k to run within 640k of memory or smaller.
The less memory available the more Clipper will swap pages in and
out of memory. This will slow the program execution speed slightly.
Clipper will use as much memory as is available at load time,
including up to 8MB of expanded memory following the Lotus-Intel-
Microsoft (LIM) Expanded Memory Specification version 3.2 or
higher.
CALLSIGN.EXE does not require expanded memory to run.
EMM386.EXE does simulate expanded memory within extended memory.
This could cause memory conflicts when CALLSIGN.EXE trys to page itself
in and out of memory and cause the program to lose its place. This can be
a hangup, skipping a portion of the program, or it could do something wrong.
UNTIL we know more about this DOS6 EMM386.EXE problem, it probably is best
to use the BAT file DOS6.BAT. This will tell CALLSIGN.EXE to restrict itself
to 640K and NOT USE expanded memory.
