/[NO]STANDARD

  Controls whether the compiler generates informational diagnostic
  messages for HP extensions to the Fortran language standard in
  effect at compile time.

  F90
    Tells the compiler to compare language features to the Fortran 90
    Standard.

  F95
    Tells the compiler to compare language features to the Fortran 95
    Standard.

  Specifying /STANDARD causes informational diagnostic messages to be
  generated for items such as the following:

   o  Extensions to language syntax

   o  Standard-conforming statements that become nonstandard due to
      the way in which they are used

   o  Tab formatting, when it appears in fixed-format source files

  If /STANDARD is specified without an option, messages are issued
  for extensions to the Fortran 95 Standard.

  The default is /NOSTANDARD (or /STANDARD=NONE).

  If you specify the /NOWARNINGS qualifier, the /STANDARD qualifier
  is ignored.

  For more information on how the compiler detects source statements
  that do not conform to Fortran language standards, see the
  description of /STANDARD in the HP Fortran for OpenVMS User Manual.
