I need to be able to check the keyboard to see if ^C (for instance) has been struck to get my mocklisp program out of a loop. I need to do this without hanging up because no key has been struck. Something like: (if (keystroke-pending) (look-at-it-and-do-something) ) Any suggestion will be appreciated. Bill McKeeman ...!decvax!wivax!mckeeman

The mods I sent out about a year ago included a function called
(pending-input) which returned >0 if there was pending keyboard input,
0 if not, and -1 if it cannot be determined.
