sounds like you mite be running under windoz ?
Delay will malfunction at times if a multitasker or you have
redirected some interrupts for background events.. like the iNT $08
for example..
I not sure how TP 7.0 does it but TP 6.0 uses a software loop..
you could use the timer 2 for a delay if you not use sound at the time.
if you use the PC speaker then poll timer 0..  it you leave timer 0 set
to its standard then its simple.

procedure HardWareDelay( Time :word); { time in Millisecs }
Var
 CompVar, LastReading:Word;
 Begin
   CompVar := (Time / 0.00000083);
