Okay. So I've started playing around with modules, the help file isn't very, er, helpful in what limits there are to modules, so I've got a question.

Is it possible to refer to variables in other modules that are currently loaded, or do classes have to be used for that?

I'll probably come up with more as I go along.

Thanks for any help.

Modules = Windows, except that Modules have the ability to share their settings with other modules and windows. Windows don't share anything, so a Module can't see the variables and stuff that are in the Windows.

It's an ability, in that there are several options that change the visibility of that module. For instance, you can keep it local to the current package, you can make it invisible to the current package, or you can make it visible to every package.

To refer to a variable in a specific module, you can use the syntax:

#SHOW @//modulename/varname

So to refer to a variable in a different module in an if statment would work like...

#IF (@//modulename/varname AND @thisvariable AND @//differentmodule/differentvariable) {say hi}

That's how I understand it?

Yep. Just keep in mind that this bypasses normal scoping rules, and you might end up with scripts that are hard to support if you start regularly accessing variables in other non-global modules. So it should only be used when absolutely necessary. Normally you'd just want to make your module Global.
