Actually, I don't think that would run as-is, since SUBPROG() was not declared above the invoking line. Simply adding SUBPROG(); above the EXPORT line should resolve it. Right?

I'm gonna gamble and leave this comment while I test it.

Oh, and I learned this from you Han, I'd like to add my thanks to you as well for nice intro lessons, plus all the other insigthful tips and replies you make. A real help in learning Prime.
