        The  setscrreg  and wsetscrreg routines allow the applica-
        tion programmer to set a software scrolling  region  in  a
        window.   top  and bot are the line numbers of the top and
        bottom margin of the scrolling region.  (Line 0 is the top
-       line  of  the  window.)   If  this option and scrollok are

-       causes  all  lines  in  the scrolling region to scroll one
-       line in the direction of the first line.  Only the text of
