It seems that none of those who have solved the problem have been
willing to share it with us, or at least that the FAQ maintainer of the
time never noticed, or felt that the TurboPower site would suffice.
AIUI, like Borland Crt, TPCrt does various things. In particular, it
initialises and provides a Delay function, and it does a lot else.
If you only want the latter, then it will be sufficient to neutralise
the Delay initialisation and not use TPCrt.Delay. Assuming that you can
actually assemble the source, it should be possible to locate the Delay
routine (seek Delay:), spot where it uses an initialised variable
(DelayCnt), spot where that is initialised, replace the failing
instruction (DIV CX) and the next (MOV DelayCnt,AX) with NOP
instructions, and arrange that the declaration of (DelayCnt) loads it
with something tolerable, say 65535. Parentheses indicate what the
Borland unit uses.
Watch out, though, for other parts of TPCrt that might use Delay.
If you need some sort of delay, it can be programmed by other means -
