Yes, it should work (but why don't you test it?).

Having said that, having a global hash shared among different program files is usually rather poor design. I can't say for sure, because we don't have enough details about what you are doing, but maybe you should share functions accessing to this hash (useing a module), or perhaps think about an OO-implementation.
