you can actually do the same thing without resorting to DOS in mscv4.0,
and I understand it works in earlyer versions as well (I got the trick
from a freind of mine using v2.something).

grokchar()
{
while (!kbhit())
   ;
return getc();
}

I am not totally sure that I have the right funtion names here, but I
know they are pretty close (you might try fgetc if getc doesn't work),
and I may have the wrong name for kbhit, but the names should be pretty
obvious.
