VMS Help PASCAL, /LIST[=file-spec] D=/NOLIST (interactive)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /NOLIST

  Controls whether the compiler creates a source listing file.  If
  you  omit  the  file specification, the compiler defaults to the
  name of the first source file, your  default  directory,  and  a
  file type of .LIS.

  The compiler does not produce a listing file in interactive mode
  unless  you  specify  the  /LIST  qualifier.  In batch mode, the
  compiler produces a listing file by default.   To  suppress  the
  listing file, use the /NOLIST qualifier.

  In either mode, the listing file is not  automatically  printed.
  You  must use the PRINT command to obtain a line printer copy of
  the listing file.
