There just does not seem to be a way to pass a table of values through lua from blitzmax properly
I only looked at Lua briefly and some time ago at that, but isn't it possible for the Blitz function to push a bunch of stuff on to the stack for Lua to pick up?
I would quite like to get more familiar with Lua myself but, as has been said, it's difficult getting definitive info on it -- I don't even know which of the existing modules is the recommended.
