Subject: What if the ts-programs won't work

5. *****
 Q: Some of your programs refuse to work on my PC. They do nothing
or just confuse the screen.

 A: Not surprising. The ts-programs are (mostly) Turbo Pascal 5.0
and 7.0 programs written for true compatibles and the good old plain
16-bit MS-DOS. They have not been written for the present 32-bit
bloated Windows systems. In particular, the programs which use
advanced screen writes (inverted colors, windowing, etc) and the so
called interrupts (direct access to PC's internal services) require
a truly compatible PC. Most frequently the problem is in the user's
non-standard video adapter hardware. A proper CGA, EGA or VGA
personal computer should have no problems, but a monochrome might.
(Monochrome PCs often are older and non-compatible anyway). My
programs have been written for vanilla MS-DOS not 4DOS. Despite
contrary claims there are incompatibilities in 4DOS. This does not
concern my programs only. The problem is general. Furthermore,
please see the later item "Allegedly corrupt packages".
   If you have problems with my programs, the first thing to do is
ensure that the .zip package is intact and then try out the
offending program on a truly compatible MS-DOS machine. If it does
not work even then, I would be very interested in a description of
the problem, preferably with a log, so that I could try to look into
it. But please try it out on a compatible MS-DOS(!) PC first before
you report the problem.
