  63        The function <STRONG>set_menu_format</STRONG> sets the maximum display size
  64        of the given menu.  If this size is too small  to  display
  65        all  menu items, the menu will be made scrollable. If this
  66        size is larger than the menus subwindow and the  subwindow
  67        is  too  small to display all menu items, <STRONG>post_menu()</STRONG> will
  68        fail.
  69
  70        The  default  format  is  16  rows,  1  column.    Calling
  71        <STRONG>set_menu_format</STRONG>  with a null menu pointer will change this
  72        default.  A zero row or column argument to <STRONG>set_menu_format</STRONG>
  73        is  interpreted  as  a  request  not to change the current
  74        value.
  75
  76        The function <STRONG>menu_format</STRONG>  returns  the  maximum-size  con-
  77        straints  for the given menu into the storage addressed by
  78        <STRONG>rows</STRONG> and <STRONG>cols</STRONG>.
