/sys$common/syshlp/helplib.hlb FORTRAN, /LIST  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /[NO]LIST[=file-spec]           D=/NOLIST

  Controls whether a listing file is produced.  You can request
  additional listing information using the /CROSS_REFERENCE and
  /MACHINE_CODE qualifiers.

  In interactive mode, the compiler does not produce a listing file
  unless you specify /LIST.  In batch mode, the compiler produces a
  listing file by default.  In either case, the listing file is not
  automatically printed; you must use the PRINT command to obtain a
  line printer copy of the listing file.

  You can include a file specification for the listing file.  If you
  omit the file specification, the listing file has the name of the
  first source file and a file type of LIS.

  The default depth of a page in a listing file is 66 lines.  To
  modify the default, assign the new number to the logical name
  SYS$LP_LINES using the DCL command DEFINE.  For example, the
  following DCL command sets the page depth at 88 lines:

     $ DEFINE SYS$LP_LINES 88

  The valid number of lines per page ranges from 30 to a maximum of
  255.  The definition can be applied to the entire system by using
  the command DEFINE/SYSTEM.

  If a source line of length 1 contains a form-feed character, the
  source code listing begins a new page with the following line; the
  line containing the form-feed does not appear.

  If a source line of length 1 contains a Ctrl/Z character, the
  source code listing contains a blank line in place of the Ctrl/Z
  character.

  Any other nonprinting ASCII characters encountered in Fortran
  source files are replaced by a space character and a warning
  message appears.

  For more information on the format of listing files, see your user
  manual.
