You could, but that would be missing the point, and it appears that you're still confusing arrays and scalars. @A is not a scalar string; it is an array. Its first element, $A[0] is a string, which you created by assigning a string (the result of join) to it.

I don't know exactly what combine() does here, but it appears to be returning an array of references to arrays. If you just want the values from the first sub-array, there's no need to join them into a string and then split them out again. Just deference the array:

my @c = combine(5,@n); # get array of arrays my @A = @{$c[0]}; # get first sub-array

UPDATE: Thanks to Anonymous for the precedence correction.
