Thanks, stevieb! I've updated my program to account for warnings raised when input lacks a modifier, but there's a problem. Am I using your technique right?

#!/usr/bin/perl
use warnings;
use strict;
my $up = "\e[A";
my @history = [];
print "Input the dice and modifier you want to roll like this: 2d9+100
+. To quit, press Ctrl-C.\n";
while (1) {
    my $dice = <>; chomp $dice;
    my @arr = split (/d/, $dice);
    if ($dice =~ /\+/) {
        my @arr2 = split (/\+/, $arr[1]);
        $arr2[0]++;
        for my $i (1 .. $arr[0]) {
            print ((int(rand($arr2[0] - 1)) + 1 + $arr2[1]), "\n");
        }
    } else {
        $arr[1]++;
        for my $i (1 .. $arr[0]) {
            print ((int(rand($arr[1] - 1)) + 1), "\n");
        }
    }
    push @history, $dice;
}

Whenever I use this code, I get this problem:

zsl@pc:~/codefolder $ perl dieroller.pl
