Positional_Qualifiers

 

/FORMAT
      /FORMAT=type

   This positional qualifier must be given for both the input and
   output file specifications. The allowable types are ASCII, DX,
   and WPSFILE. The file extension of the input and output file
   must be given and they must agree with the selected format: for
   ASCII files the file extension must be .TXT, for DX files the
   file extension must be .DX, and for WPSFILE files the extension
   must be .WPL. Failure to use the proper extension will result in
   unpredictable results.
