Hi,
the following example doesn't compile:
use strict;
use warnings;
sub test {
print $counter . "\n";
}
my $counter = 0;
while($counter < 5) {
test();
$counter++;
}
It says "Global symbol "$counter" requires explicit package name ...".
When I put the subroutine after the 'while' loop, it works just fine, so
what's the problem?
