( #3333=superdoc: print w/ replies, xml ) Need Help??
Firstly I have a scalar that will contain either a value or a reference to an array. If it's an array I want it to do one thing. If it's a scalar value I want it to do another. What's the correct way of doing this so I don't get errors?

Have a look at ref in the documentation. It has a couple of examples of what you are looking for.

Secondly How can a make a global variable truely global, so that it will be accessible by all packages without using package::variable.

You don't. Well sortof, Can you create *real* global variables?
