getch grabs a single character from the input buffer.

var c:string(1)
getch(c)
put c


hasch returns true if there's anything in input buffer waiting to be processed. It is generally used to skip getch so that program continues even without user's input.


var c:string(1)

loop
if hasch then
    getch(c)
    locate(1,1)
    put "you've pressed ",c
    delay(1000)
end if
locate(1,1)
put "waiting..."
end loop
