The frame; command tells the interpreter when a process is done for one game cycle. When the frame; is reached, the screen is updated. If there are several processes running, the screen is updated once every process has reached it`s frame; statement.

It is commonly used in loops of processes that should do something like moving around by a certain amount of pixels per game cycle (or per frame).

Example

---

process square()
 begin
   graph = new_map(5,5,16);
   map_clear(0,graph,rgb(255,255,255));

   loop
     if(key(_left))x-=2;end; 
     if(key(_right))x+=2;end;

     frame; //<-vital part
    end;
  end;

This example process would give you a square you can move around the screen by 2 pixel before it gets showed again, before the game cycle is over, before the frame; happens. If there would be no frame; in the loop, it would just run and run and the interpreter would wait and wait and wait for the frame; which would just result in freezing.
