Structured Programming

[thegrogen]

So it's more of a way of accessing a mathematical equation?

Kind of, but it's more than that. You can also use the return value to return error codes and whatnot. APIs like SDL also use functions to return pointers to data structures. Ever seen anything like this?

Code:

Dim surf as SDL_Surface ptr
surf = SDL_LoadBMP ("Blah.bmp")

SDL_LoadBMP is a function that returns a pointer to an SDL_Surface.
