First put the directive Replace DrawStatusLine; before including the library; define the global variable invisible_status somewhere. Then give the following redefinition:

[ DrawStatusLine i width posa posb;
   if (invisible_status==1) return;
   @split_window 1; @set_window 1; @set_cursor 1 1; style reverse;
   width = 0->33; posa = width-26; posb = width-13;
   spaces (width-1);
   @set_cursor 1 2;  PrintShortName(location);
   if (width > 76)
   {   @set_cursor 1 posa; print "Score: ", sline1;
       @set_cursor 1 posb; print "Moves: ", sline2;
   }
   if (width > 63 && width <= 76)
   {   @set_cursor 1 posb; print sline1, "/", sline2;
   }
   @set_cursor 1 1; style roman; @set_window 0;
];
