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

  Controls whether the listing file includes source lines from files
  or text modules specified in INCLUDE statements.

  The [NO]LIST option on the INCLUDE statement overrides the
  /SHOW=[NO]INCLUDE qualifier on the FORTRAN command line.
