Adding arrays?

[Don Johnson]

Robert -

You solution will work fine.  The only trouble you might run into is if 
you don't want to allow duplicate values in the resulting array.  If 
@TempArray contains values already in @FinalArray, and you want to 
disallow duplicates, you could use the keys of a hash to ensure no 
duplicates:

%hash = ();
foreach $key (@FinalArray) {
    $hash{$key} = 1;    # we've seen this key
}
foreach $key (@TempArray) {
    $hash{$key} = 1;    # we've seen this key
}
@FinalArray = keys %hash;

This solution, however, introduces another problem: what if you wanted 
to preserve the order of the original arrays?  Hmmm...
