if you think then all you have to do is exit loop when some one presses any key so, try this.

code:
if hasch then
exit 
end if

put this code in your program any where

That can be reduced to one line there zedx:
exit when hasch
Aswell generally you would want this placed at the end of the loop, or beginning just incase it causes anything funny to happen.

Also if you would like it to run only on one key, such as 'y', we can add to that code.
exit when hasch and getchar='y'
The reason you need to leave the hasch in there is that if you don't then the computer will run getchar even if no key is pressed, this will cause the program to stop and wait for input whereas if you place the haschh infront it will only evaluate the second half if hasch returns true. That means it will only run getchar when there is already a character waiting, thus not stopping the program. This also means the hasch must be placed before getchar or it will not work.
