That works fine, Bob.

I was hoping to avoid using an index. I'm of the school of thought that the fewer variables a program has - especially global variables, see http://c2.com/cgi/wiki?GlobalVariablesAreBad - the easier it is to understand and maintain.

Still, this gets me over that hurdle ;-)

    I just wanted to point out that the index ($i) does not have to be global. You could write:

    while (my $i < @a)

    ... and have $i scoped to the while loop. Check out Lexical scoping like a fox.
