  /NOSTANDARD

  Causes  the  compiler  to   generate   messages   whenever   the
  compilation  unit  uses Compaq Pascal language extensions, which
  are nonstandard Pascal features.  b

  See the "Compaq  Pascal  Language  Reference  Manual"  for  more
  information on standard Pascal features and the Pascal standards
  (ANSI, ISO, and Extended).  The options are as follows:

     NONE
       Disables standards checking.

     ANSI
       Uses the rules of the ANSI standard.

     ISO
       Uses the rules of the ISO standard.

     EXTENDED
       Uses the rules of the Extended standard.

     [NO]VALIDATION
       Performs validation for the given standard.

  The /STANDARD qualifier allows you to use only two options.  The
  first  option  selects  the  standard  to be used (ANSI, ISO, or
  EXTENDED).  The second option determines  whether  the  "strict"
  validation rules are to be enforced, [NO]VALIDATION.  Therefore,
  /STANDARD=(ANSI, ISO, VALIDATION) is not allowed since both ANSI
  and ISO are specified.

  By default, these information-level messages are written to  the
  error  file  SYS$ERROR.   Note  that using the VALIDATION option
  changes   all   nonstandard   information-level   messages    to
  error-level messages.

  The  /STANDARD  qualifier  without  options  is  equivalent   to
  /STANDARD=(ANSI,    NOVALIDATION).     /STANDARD=VALIDATION   is
  equivalent   to   /STANDARD=(ANSI,VALIDATION).    The   negation
  /NOSTANDARD is equivalent to /STANDARD=NONE.
