PROP SAMPLE CASE:  BARNARD'S RV-6A - Max Cruise
 @
 @ NOTE- The "@" sign allows comments to be inserted on the remainder of a line.
 @       The INPUT file is always required to run PROP and must begin with a
 @       single title line. All input is echoed to the OUTPUT file which
 @       subsequently may be used as an input file by renaming it to INPUT.

 CONTROL         @ Input group name for control group type data

  NPAYOFF=2      @ 0=Calibration, 1=Point Design,  2=Max Velocity
  IOPT=1,2,3     @ 1=AF, 2=DIAM, 3=RPM - Enter one to three values
