     X-F-W Data supply for smoothing from datafile  "XFWDAT" .

     Just below, input number of monotonic sections < 16
0

     Calculation incomplete becasue required 
      number of monotonic sections is less than one.
      It is recommended: 1<= Number Monotonic Sections < Number of data


     (Termination due to subroutine TRIVIA.)
