Hi,
so you can create a function called setvar() or getvar(), but neither function is native to Lua, you have
to create the function.
I could create a function GoGetMeACupOfCoffee(), but just creating such a function doesn't really help me much.
It is no more native to Lua than getvar().
There are Lua functions which are useful, like math functions, string functions, and file functions, but by far and away the most
useful functions in Mach4 programming are not native to Lua but API's to Machs core or to Machs GUI.
