Hook in Program which does not use LUA?

["Koch, Chris, VF-DE" <chris.koch@...>]

Hi

Im very new to lua.
Just want to know if it is possible to
LUA to use functions of a compiled win32
binary to control the program.
I mean for example to let a character move
to x,y coord by calling the subroutine within
the binary for moving.

I heard this is possible if the program uses
LUA on it`s own. But if not?!

Maybe some of you has already some experience
to tell me whats possible and what not.

Cheers
