Mouse

xyin :: D -> D -> D -> D -> D -> (Sig, Sig)

Sense the cursor position in an output window. When xyin is called the position of the mouse within the output window is used to reply to the request. This simple mechanism does mean that only one xyin can be used accurately at once. The position of the mouse is reported in the output window.

 kx, ky xyin iprd, ixmin, ixmax, iymin, iymax [, ixinit] [, iyinit]
