/qualifiers

  Indicates either special actions to be performed by the compiler or
  special properties of input or output files.

  file-spec-list

  Specifies the source files containing the program units to be
  compiled.  You can specify more than one source file.  If source
  file specifications are separated by commas (,), the programs are
  compiled separately.  If source file specifications are separated
  by plus signs (+), the files are concatenated and compiled as one
  program.

  When compiling source files with the /OPTIMIZE qualifier (the
  default), concatenating source files allows full interprocedural
  optimizations to occur.

  In specifying a list of input files on the Fortran command line,
  you can use abbreviated file specifications for those files that
  share common device names, directory names, or file names.  The
  system applies temporary file specification defaults to those files
  with incomplete specifications.  The defaults applied to an
  incomplete file specification are based on the previous device
  name, directory name, or file name encountered in the list.

  The output produced by the compiler includes the object and listing
  files.  You can control the production of these files by using the
  appropriate qualifiers on the Fortran command line.

  For complete information on these command-line parameters, see the
  HP Fortran for OpenVMS User Manual.
