My name is Andrea. I'm using Turbo C++ on an old PII 350 MHz with dos 7. I've written a while cycle which does something. I have to check a which letter of the keyboard has been pressed without checking it in the cycle in order to avoid it to slow down. Is there a way to set an interrupt like in arduino to stop the cycle only when a key is pressed? I've tried with bioskey(0) in the cycle but it slows it down too much....
