Intrinsic-138 SetBorderColor

138: SetBorderColor(R, G, B);

This intrinsic sets the color of the small border around the active portion of the console window. The active portion of the console window depends on the current video mode. For example, if the video mode is set to mode 6, the screen will be 640 pixels wide by 200 pixels high and the border will be just outside these dimensions. Currently the border is four pixels wide.  EXPL supports special RGB modes that make them compatible with pervious VGA color palettes and versions of XPL0.
