I am not positive what you are really wanting here...
my $Line = some string;
for(split(//,$Line)) {
my $char=$_;
}
But maybe you want to be able to access those characters again later on, in which case
my $Line = some string;
my @array=split(//,$Line);
for(@array) {
my $char=$_;
}
I am assuming you will have some additional functionality inside the for loop since
$char will be
re-written by $_ on every pass.
