Hi all, 

Running the following program outputs:
Perl 5.008004
undef
undef
undef
2
but it should output:
Perl 5.008004
undef
undef
undef
undef

The code goes as follows :- 
#!/usr/bin/perl -w

print "Perl $]\n";

sub show {
my ($val) = @_;
if (! defined $val) {
print "undef\n";
} else {
print "$val\n";
}
}

sub sb {

my $v1;
$v1 = -1 if 0;

my $v2 = -2 if 0;

show $v1;
show $v2;

$v1 = 1;
$v2 = 2;

}

sb;
sb;
