Some sine and cosine program. Check it out. More of example code, but useful anyway.

Example code

Program cosine;
Begin

    set_fps(60,0);

    timer[1]= 200;
    Repeat
        if(timer[1]>=200)
            timer[1] = 0;
            x = new_map(20,20,8);
            map_clear(0,x,rgb(rand(0,255),rand(0,255),rand(0,255)));
            ball(x);
        end
        frame;
    Until(key(_esc))

    let_me_alone();

End

Process ball(graph)
Begin

    z = 0;
    Loop
        x = 160+cos(z)*150;
        y = 100+sin(z*2)*90;
        z+=2000;
        frame;
    End

End

Used in example: set_fps(), new_map(), map_clear(), key(), let_me_alone(), cos(), sin(), timer, x, y
