Description

SET INKEYDELAY ON controls the wait period for the INKEY() function. The INKEY() function returns a zero if no key has been pressed, or the ASCII value of the key which has been pressed. When INKEYDELAY is ON, a check is made once a second for a keystroke. If INKEYDELAY is OFF, the check is made continually. The default setting for INKEYDELAY is OFF. If INKEYDELAY is set OFF, then DO WHILE loops that wait for user input with the INKEY() function may be very CPU intensive.


Example

set inkeydelay on
do while inkey()=0
//...
enddo
