Yes - both arrays and linked lists ARE ALWAYS GLOBAL. From the help file:

Arrays are always globally accessable in PureBasic. This means that they can always be accessed from inside procedures without needing to use the Global or Shared commands.

Lists are always globally accessable in PureBasic. This means that they can always be accessed from inside procedures without needing to use the Global or Shared commands.

uhm.....yes!

You have to keep in mind that purebasic is a one-pass compiler so you must declare your lists and dimmed vars on top of your code or at least above the procedures that's gonna use them...

Variables and Linked Lists can have the same Name, because they are two different things.
So what you do here, is declare a Global LONG Variable and then a Linked List of YO_LIST Type(which is Global by design).
