What OS is it running in? I gladly forgot most about Autosys after quitting $job - 1.

The following runs in Linux and reacts to signals as expected:

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

local $SIG{USR1} = sub {
    say STDERR "Signal 1 caught.";
    alarm 0;
};

local $SIG{USR2} = sub {
    say STDERR "Bye!";
    exit
};

my $sum = 0;
while (1) {
    $sum += $_  for 1 .. 100;
    say $sum;

    say STDERR scalar localtime, " Sleeping...";
    sleep 10;

    say STDERR scalar localtime, " Ready!";
}
