Hello,
There is a scope mistaken above.You declare $whileloop at the outside of the
loop,while here you re-declare another $whileloop with "my".This $whileloop is
different from the former one.So "my $whileloop = 99" shouldn't change the
switch's value which is default 0,then the loop can't get exited.
For Perl's variables scope,you may take a look at:

Hope this useful.
