in reply to Values passed into a sub routine

use named Parameter passing concept like


build_url(account => "test",transaction => "test1", location => "India
+", fname => "Nikhil", lname => "jain"); 

build_url(account => "test", fname => "nikhil", lname => "jain"); 

build_url(account => "test" ,transaction => "test1", fname =>"nikhil",
+ lname => "jain"); 


 
sub build_url {
my (%args) = @_;
my $fname = $args{fname} || "Bob the Builder";
my $lname = $args{lname} || "none that we know";

    This is the way to go imho. Remove the $ in the parameter names though (so account => "test" instead of $account => "test") I like this idiom: 
    sub build_url {
  my %param = ( fname => "default value",
                ...,
                @_
               );
  ...
  # do stuff with $param{account} etc.
}
