    Hi all,
    I was wondering if you could help out with this problem that I am having.
    What I am trying to do is detect keyboard input in a while loop without
    halting/pausing the loop until the key is pressed (without hitting return).
    I looked at serveral faq's on the net and installed the cspan readkey module
    and neither seems to work most likey its me since I am getting frustrated.
    but anyway here's a sample code.

    while (1) {
        if (keypress) {
            print "you've pressed: $key\n";
        }
        else {
            print"Continuing to loop...\n";
            sleep 1; # delay the loop incase you need to control-c out.
        }
    }

    TIA!
