excuse me for the idiotic comment, but i have tried to do the same as the OP and return data from a sub. like say this code for instance:
use warnings;
use strict;
use diagnostics;
my $string = "";
add_i_to_string($string);
sub add_i_to_string {
my ($string) = @_;
my $new_string = $string . "i";
add_am_to_string($new_string);
}
sub add_am_to_string {
my ($string) = @_;
my $new_string = $string . " am";
add_ironman_to_string($new_string);
}
sub add_ironman_to_string {
my ($string) = @_;
my $new_string = $string . " ironman";
string_print($new_string);
}
sub string_print {
my ($string) = @_;
print $string;
}
#prints "i am ironman"
now my question is, would it not be better to just pass the data to another sub for printing, or is there a specific reason we should be returning data outside of a sub instead of just passing it to another?
