hmm, have a (hopefully (: ) quick question: how would i return the result of a for() loop within a subroutine? example:
 
sub scroll {
my ($i) = @_;

my @x = for (my $x=0;$x!=(length($i)+1);$x++){ substr($i,$x,1), "\n"; 
+};
return @x;


}

now, this doesn't work, and spews forth quite a few warnings and errors (: but how would i go about returning the value?
it might be helpful to note that when i write it as: 
sub scroll {
my ($i) = @_
for (my $x=0;$x!=(length($i)+1);$x++){ print substr($i,$x,1), "\n"; }

}

it works.
