Hi all,
I write a small script to see what is the difference
between calling methods and regular subroutines. Then
I use Data::Dumper to see the data structure. What I
expecte is to print out a string(This is the data1 1
and data2 2) after using Dumper. But here are the
results I get from using Dumper;
$VAR1 = 1;
My question: What does it mean? Does it mean
successfully calling either a subroutine or method?
Thanks in advacne,
Li
##codes
use strict;
use warnings;
use Data::Dumper;
use Bar;
my $call=&Bar::print_result(1,2);#call as a regular
routine
print Dumper $call;
print "\n";
my $call2=Bar->print_result(2);#call as a method
print Dumper $call2;
print "\n";
exit;
##package Bar
package Bar;
use strict;
use warnings;
sub print_result{
my $data1=shift;
my $data2=shift;
print "This is the data1 $data1 and
data2 $data2", "\n";
}
1;
##screen output
This is the data1 1 and data2 2
$VAR1 = 1;
This is the data1 Bar and data2 2
$VAR1 = 1;
