In our application I have a dedicated perpetual process that I want to run until the user presses a key on the keyboard. How can I check for a keypress without halting the perpetual process while waiting input. The code needs to look something like this.



KEYPRESSED=0



LOOP	

   CHECK.KEYBOARD.STATUS(KEYPRESSED)

   UNTIL KEYPRESSED

REPEAT



Any insight as to how the keyboard buffer can checked from AREV would be appreciated.
