Provided that they are "well-behaved" it is possible to run MS-DOS
applications under Windows NT. Indeed they run better under NT than do the
same applications under Windows 95 and 3.1. They are run as separate threads
and therefore can be scheduled along with 32-bit Windows applications.
The well-behavedness is basically that they cannot access the hardware
directly. Microsoft call this a security feature whereas it is properly a
system integrity issue. The emulators under MacOS show that system integrity
can be maintained. Further the emulators under Linux can do the same in a
complete multi-user, multi-programming, multi-tasking and multi-thread
environment. But again my bigotry is showing. Then again what do I know I'm
just a computing scientist. :-)
With the availablity of the SignWriting 4.3 source code perhaps it would be
possible for some one to produce a version that is well-behaved under NT 4.0?
Might it be possible to produce a Mac native version too? The Metrowerks
CodeWarrior for Mac Pascal compiler is supposed to handle Turbo Pascal fairly
well. The problem will be replacing the assembler code.
[Valerie perhaps you and I should discuss the last two things off-list.]
