[guobbs]

I have two sub function, have two same local variable name in these sub functions.

sub fun_1 {
       my $file = "1.pl";
      ......
}
sub fun_2 {
       my $file = "2.pl";
      ......
}

first execute sub fun_1, the local variable panel display "$file:1.pl". when execute sub fun_2, the local variable panel display "$file:1.pl" yet.
