in reply to Split function

If you can't have it die, you can make it do that if split splits into only one part.

(my ($s, $a, $c, $r) = split /[,\t]/) == 1 and die;
or, alternatively, you can do
die if not defined $a;
edit code fixed, thanks ColonelPanic

    If you are going to do error checking, why not do it properly? Check that all fields are present:

    (my ($s, $a, $c, $r) = split /[,\t]/) < 4 and die;
    or:
    die if not defined $r;

    (Also, you had a typo in your code: extra paren)
