# PEEKCHARQQ

Run-Time Function: Checks the keystroke buffer for a recent console keystroke and returns .TRUE. if there is a character in the buffer or .FALSE. if there is not.

## Module

USE IFCORE

result = PEEKCHARQQ( )

## Results

The result type is LOGICAL(4). The result is .TRUE. if there is a character waiting in the keyboard buffer; otherwise, .FALSE..

To find out the value of the key in the buffer, call GETCHARQQ. If there is no character waiting in the buffer when you call GETCHARQQ, GETCHARQQ waits until there is a character in the buffer. If you call PEEKCHARQQ first, you prevent GETCHARQQ from halting your process while it waits for a keystroke. If there is a keystroke, GETCHARQQ returns it and resets PEEKCHARQQ to .FALSE..

## Example

     USE IFCORE
     LOGICAL(4) pressed / .FALSE. /
     DO WHILE (.NOT. pressed)
       WRITE(*,*) ' Press any key'
       pressed = PEEKCHARQQ ( )
     END DO
     END
