Definition

Angle is a predefined local variable which holds the angle (measured in 1/1000 of a degree) at which the graphic of that process (assigned by the graph variable) will be drawn.

Example

To make the graphic of a process spin:

Process spinning_graphic()
Begin
   graph = load_png("image.png");   //load the graphic and assign it to the graph variable
   x = 100;     //Position the graphic 100 pixels
   y = 100;     //from the top and left of the screen
   Loop
      angle += 1000;    //increase the angle of graphic by 1000 each frame. 1000 = 1 degree.
      frame;
   End
End

This process will spin the graphic stored in the file "image.png" by 1 degree each frame.
