Thanks Andy. So are .dlls "included", or do you just
place the .dll in the \windows\system\ directory and
call the functions directly?  I would imagine the
latter, since you state that other languages can
access .dlls written in most any language (with the
possible parameter restrictions, of course) and
without revealing the source code.
