fdl-file-name

   Use this parameter to specify the FDL file to be created,
   modified, or optimized during this session. If you specify an
   existing FDL file for modification or for optimization, the
   output file is the next higher version of the file being modified
   or optimized. In all cases, you have the option of using the
   /OUTPUT qualifier to specify the output FDL file. The default
   file type is .FDL.
