I want a script that constantly accepts user input, but runs a
subroutine every second to do other work. My attempt:
$|=1; $SIG{'ALRM'}= "\&alarm_sub"; &alarm_sub;
while (<>) {print "You typed: $_\n";}
sub alarm_sub {print "ALARM!\n"; alarm 1; return;}
fails miserably. What's the right way to do this?
