CURSOR_VERTICAL

  Moves the cursor position up or down on the screen by the number of lines
  you specify.  The cursor does not move right or left.  CURSOR_VERTICAL
  allows free cursor motion.

  Syntax

     [integer2 :=] CURSOR_VERTICAL (integer1)

  Parameters

     integer1   The number of screen lines to move the cursor.  Positive
                values are toward the bottom of the screen.  Negative values
                are toward the top of the screen.

     integer2   The number of lines that the cursor actually moved.  If you
                specified a value for integer1 that would put the cursor
                outside the current window and if SET
                (CROSS_WINDOW_BOUNDS...) is set to OFF, CURSOR_VERTICAL
                moves the cursor as many lines as possible while keeping the
                cursor in the current window.

  Example

     CURSOR_VERTICAL (+5);

  Moves the cursor position five lines down (toward the bottom of the
  screen).
