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

  /[NO]STANDARD[=(option[,...])] D=/NOSTANDARD

  Controls whether the compiler produces informational diagnostics
  for extensions to ANSI X3.9-1978 (FORTRAN-77) that can be
  determined at compile-time.

  If you specify /STANDARD with no arguments, it is equivalent to
  /STANDARD=(NOMIA,SEMANTIC,NOSOURCE_FORM,SYNTAX).  The /STANDARD
  qualifier has effect only if you specify /WARNINGS, either
  explicitly or by default.

  Note the difference between the /STANDARD and /F77 qualifiers.  The
  /STANDARD qualifier causes diagnostics to be produced for
  non-standard features.  The /F77 qualifier causes the FORTRAN-77
  interpretation to be chosen for constructs that mean different
  things in FORTRAN-77 and previous versions of VAX FORTRAN and Compaq
  Fortran 77.

  /NOSTANDARD is equivalent to /STANDARD=NONE.
