Matching

[Sitha Nhok]

Hi,
 
Is there anyway to match a string in a 2-dimensional array only at one
index?  For example, say I have this 2-d array:
 
@AoA = (
                ["ABC", "BCD"],
                ["CDE", "DEF"],
                ["EFG", "FGH"],
            );
 
Then I wanted to see if "CD" exist, but only in column index 1
($AoA[$row][1]).  Is there a way to do this w/o using a "for" loop
within a "for" loop?  Thanks.
