Is there a way to abort a program after M milliseconds?
Your question can be interpreted in two ways: 1. The program really just waits for user input. If this input can be handled on the keystroke level, you can call (key 100) to wait for 100 ms. 2. The loop is doing something and you want to interrupt that Then you can either use (poll 0) to check standard input in the loop, or install a signal handler like *Sig1 and do a (throw ...) in it. ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
