It's a little-known fact that you can use the module name, and dot syntax
together. So, if you have a module named "Globals", and a public variable
in the module named "Foo", you can refer to it in your code as Globals.Foo.

That said, this is not usually a good idea. Most shops use coding standards
that emphasize scope as part of the name. I use an "m" prefix to designate
module-level scope, and a "g" prefix to indicate global-level scope. So,
using the example above, my global scoped module would be named something
like "gsFoo" (to indicate a global string variable", or "msFoo" to indicate
a module level string variable.

BTW - why are you using SP3? SP5 has been out for a long time now, and SP6
was recently released (but, many are urging caution before applying SP6).
