Re: problems passing variables between subroutine

Please use a reference an array rather than an actual array in:

sub create_output (\@$)  {
    
    my (@array_of_lines, $entry_no_new) = @_;
[download]

as below:

use feature ":5.14";
use warnings FATAL => qw(all);
use strict;
use Data::Dump qw(dump pp);

sub foo(\@)
 {my ($array) = @_;
  say "@$array";
 }

my @array = qw(1 2 3);
foo(@array);

Produces

1 2 3

Please don't encourage needless use of prototypes! Also in simple cases passing arrays by reference serves only to obscure the code so don't do that. Just because a technique fixes a problem in some cases, doesn't mean it should be used in all cases. Be selective about the habits you acquire and apply them along with a little consideration rather than blindly following a set of rules. True laziness is hard work	[reply]
