Uh, not very well.

You need to export getXtable.  See the external C core files.  I don't 
know how to do that from a Basic DLL.

I'd still lean toward making a glue external, but if I did this it 
would depend on what I find out from looking at the Basic dll format.

I think it might be easier to take a simple external example (in C) and 
learn just enough C to do the math functions.

If you are passing a large collection of vectors and get a large 
collection back, you need to address the representation of that.

If you are pass a single 3D vector and some transformation values and 
getting a vector back, I'd think on optimizing the Transcript.
