With this, I'll have a question again =)
how about : for (my $x = 0; $x <= 100; $x++){} ?
In every loop, $x return the value to the middle,
and the middle design to roll another loop or not.
It is doing something similar to if then else, but
it also returning vals and condition signals...
So.... what is this ? And when I write as
for (0..100){} there is quite no difference, still
an invisible $x, as $_... so...sorry, dunno how to ask.. =)
