/LIST[=file-spec] D=/NOLIST

 /[NO]LIST

 Requests a source listing file.  You can request additional listing
 information using the /MACHINE_CODE and /SHOW qualifiers.

 The default is /LIST for a batch process, and /NOLIST for an
 interactive process.

 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.

 In interactive mode, the compiler does not produce a listing file
 unless you include the /LIST qualifier.  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.

 If a source line contains a form-feed character, that line is
 printed but the form-feed character is ignored (does not
 generate a new page).

 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 HP
 Fortran source files are replaced by a space character and a
 warning message appears.

 For more information on the format of listing files, see the HP
 Fortran for OpenVMS User Manual.
