in reply to Passing a hash between subs

Hi ,

The $ref in the sub foo where you get it and I guess , from the way you populate your hash in the sub bar , you should be getting the location by having
sub foo { my $location_text = $locations('id'); }

The passing of hash can be through a reference too like

sub bar { return \%locations; } sub foo { $locations = &bar($dbh); print "The reference returned from bar is : [$locations] +\n"; %location_Names = %$locations; }

You can use some debugging to see the hash values in course of program like use Data::Dumper which will give you the hash's values in course of your program in tree forms itself , so that it shall be easy and helpful
