in reply to prepend string to entire array

If you mean that you want "A1", "B2", C3", then this'll do it: 
my @array2 = map "$array[$_]$array1[$_]", 0..$#array;

    Works, but I need @array2 to contain all possible combinations. Such as:
    A1 B1 C1 D1 E1 F1 G1
    A2 B2 C2 D2 E2 F2 G2
    A3 B3 C3 ..........

      Um, don't you think you should have stated that in your orginal question? :|

      But i do find it amusing that you asked merlyn for code that does combinations. ;)

      UPDATE:
      Limbic~Region pointed me to Re: Character Combinations in which he links to a module tye wrote, Algorithm::Loops. Give it a look.

      I'm in a good mood.

      @array  = qw(A B C D E F G);
@array1 = qw(1 2 3 4 5 6 7);
@array2 = map { my $c=$_;map "$_$c", @array } @array1;
