Here's another twist on this. The Message Box has the ability to create "global variables" - click the 4th icon from the left in the toolbar at the top left of the message bar.
If you define a global variable with a name that starts with a $ sign, it seems to be available from any script without declaring it, thus making it truly global. It also shows up in the Variables tab of the script editor window. If you want a variable that is truly global without having to declare it everywhere, this seems to offer that option. You'd have to find a way to create such variables by script rather than through the message box though - maybe they are created as OS environment variables with a shell command, like the other $ variables?
