   #include example.hdr

   proc Test_SLIST
   vardef
      _SLIST pList
      uint   n
   enddef
   pList := pickinit()
   for n := 0 to 6
      pickadd( pList, __daynames[ n ] )
      ? pickcount( pList ), pickstr( pList, n + 1 )
   next
   pickclear( pList )
   endproc

   proc main
   Test_SLIST()
   endproc
