Re: where do you put your subs

This is simply a matter of taste, IMHO. But, I have no "main" code, per se. rather..

#!perl

use strict;
use Modules;

main();

sub main
{
    #main algorithm, calls to other subs
}

sub1
{#sub code}

sub2
{#sub code}

etc..

I find this method to be extremely helpful in having variables with a limited scope. Just say "NO" to globals.

I like to do `#!/usr/bin/perl -w exit main(); sub main { ... return (0); }` [download] Maybe I'm just a C programmer at heart. 1. dude, what does mine say? 2. "sweet", what about mine? 3. "dude", what does mine say? 4. GOTO 2	[reply] [d/l]

See now I would write `sub main { } exit main;` [download] But when you do your main as a sub its different to doing your main as code as it ivolves a lexical scope. But this is good practice, in fact tye somewhere has a node covering a similer but more involved version of the same thing. Yves / DeMerphq -- When to use Prototypes?

The code-flow is not really logical: why do you exit before performing your tasks? Is there any reason to have the exit statement before the sub declaration? And real C programmers at heart write some `for (;;)` instead of `... 4 GOTO 2` :) 44696420796F7520732F2F2F65206F 7220756E7061636B3F202F6D736720 6D6521203A29202D2D204A75657264	[reply]
