How to derive HTML from a drupal module

Question

this may be basic, but I just started using Drupal (6 battles).

I create a module and get a callback that some html should return. I could just do something like this:

function myModule_myFunction(){
    $r = '';
    $r .= '<h1>'.$variable.'</h1>';
    return $r;
} 

But I would rather separate the logic and presentation and put this in a separate file or something else. HTML in lines is ugly!

What is the drupal way to do this? No need to use the system as far as I know.

Answer 1

a theme system is a drupal way to do this.
