Execute a script with lua_dofile. Read and write variables with lua_getglobal
and lua_setglobal.

Here is a simple example:

-- script hi.lua

print(name)

-- C code

	lua_dofile(L,"hi.lua");		/* outputs "nil" */
	lua_pushstring(L,"John Lennon");
	lua_setglobal(L,"name");
	lua_dofile(L,"hi.lua");		/* outputs "John Lennon" */

Hope it helps you get started.
