in thread compare two strings and return only he unique values.

Won't show "A" when:

my ( $str1, $str2 ) = ( 'ABCDEA', 'BCDEO' );

    Yeah, I know. But the OP said:

    I am trying to display unique values from two strings

    So is 'A', in your dataset, unique or not?

    Depends upon a better spec, I suppose...

    Update: smls (below) already pointed this out;

      Your solution is elegant and works beautifully with "ABCDE", "BCDEO" -- the OP's two initial strings. But the OP later included "ABCDE", "BBBBB" as options, clearly indicating the possibility of character reptition. Quite agree that a clearer spec would help...
