<quote>In my simple example Foo.pm is a source file - and only when it is changed, pp is run.</quote> Thank you for explaining what it is, my questions were 'what is the use?' and 'why do you need them?'

I found out that .pm files are perl modules, and from what I understand you can compare them with object files in C(++). Is that right? If so, I could speed up things if I first created .pm of my functions file and constant declaration files before compiling the executables, as I call them as require basic_func.plin all .pl files. That is the way I was thought to do.

The extension .fmt, used in your examples is according to Google the extension for Visual Fox pro file and not .pl like perl

I'm using PAR:Packer, as this was the way within Perl, I found out on Google to create .exe files in a free way. Maybe I'm wrong on this and I should take another turn in creating .exe files in a faster in more reliable way

nroff and groff are typesetting systems on Unix systems.

With the following two commands you can create a printable file and send it to your printer:

Karls-Mac-mini:~ karl$ groff -mm ch01 > ch01.fmt

Karls-Mac-mini:~ karl$ lp ch01.fmt 

Update:...ch01 is formated file...

The very basic blueprint to include code in your perl program(s) is:

Update: Foo.pm

  package Foo;
  use strict;
  use warnings
  our $VERSION = '1.00';
  use base 'Exporter';
  our @EXPORT = qw( foo );
 
  sub foo {
     return "bar\n";
  }
 1;

# later, in your main program you say:
use strict;
use warnings
use lib q(/path/to/Foo);
use Foo;

print foo();

See perlmod

pp for creating executables is OK (and cool) but keep in mind that this just are self extracting archives - you can unzip them.

Hi Karl

I will use your examples and maybe it will become clearer to me what you try to explain. And how to use this info in my solutions.

I've changed the extension of one file from .exe -> .zip and you are 100% right. I'm completely shocked! Besides the advantage of not to create a Perl environment on systems I don't see the benefit of using pp (PAR::Packer). Is there a way to prevent this and use a module that doesn't make retrieving the source code that easy!!! And produce real machine code.

As I previously suggested, read and understand the documentation, this is all explained there. If you don't understand the benifit of pp, why are you using it?
