Drupal 7 global javascript variables

Hi everyone,

In my Drupal 7 installation, I have 2 separate JavaScript files that are loaded by my sub-themes (base and admin sub-theme) - I don't know if this is useful information or not, but:
What if I want to define a JavaScript variable in the first js file that is loaded and use it in the second one? How should I define it?
Basically, the question could be: How to define global JavaScript variables in a Drupal environment?

I am using jQuery.

javascript variables are global by default. doesn't matter if it is an included file or inline script tag. variables defined globally are available globally. For example, in jquery "$" is a variable defined as a function that is usually an included js file. The "$" function should be available anywhere in your scripts after jquery has loaded.

drupal is not special. Its just like any other javascript variable.

Code:

<script type="text/javascript">
var test = "hello world";
</script>

For a variable to be available inside an included file, it would just have to be defined before the file is included. variables defined in one file are available in later files in the order they appear in the source.
