 MousePoll row%, col%, lbutton%, rbutton%

 Remarks
 The MousePoll procedure uses the following arguments.

 row%
 ----
 A variable that contains the row coordinate for the mouse cursor.

 col%
 ----
 A variable that contains the column coordinate for the mouse cursor.

 lbutton%
 --------
 A variable that contains the status of the left mouse button.

 rbutton%

 A variable that contains the status of the right mouse button.

 MousePoll places the row and column position of the mouse cursor into the
 row% and col% variables. The MousePoll procedure also determines the status
 of the left and right mouse buttons, and places the status (TRUE if pressed
 or FALSE if not) into the lbutton% and rbutton% variables, as appropriate.

 MousePoll is used throughout the User Interface toolbox whenever the
 location of the mouse cursor or the status of the mouse buttons is required.
