I need to write an external for LiveCode in C++, but I doubt my ability to do it.

[Roland Huettmann]

But I would also appreciate a reply, maybe from Peter, which is of general
interest to all of us.

Optimizing is one possibility, then the question about what would LC
Builder accomplish, and then C++, if nothing else does the job fast enough?

I am thinking about some optimisation algorithms which are already
available in C++ and would probably execute not well enough in LCS.
