/WARNINGS=(opt[,...]) D=/WAR=(ALI,NOA,NOD,GEN,GRA,NOI,NOT,UNC,UNI,NOU,US)

 /[NO]WARNINGS

 Controls whether the compiler generates informational (I-level) and
 warning (W-level) diagnostic messages in response to informational
 and warning-level errors.  The default is /WARNINGS=(ALIGNMENT,
 NOARGUMENT_CHECKING, NODECLARATIONS, GENERAL, GRANULARITY,
 NOIGNORE_LOC, NOTRUNCATED_SOURCE, UNCALLED, UNINITIALIZED NOUNUSED,
 USAGE).

 [NO]ALIGNMENT
   Controls whether the compiler issues diagnostic messages when
   variables or arrays (created in COMMON or EQUIVALENCE statements)
   are declared in such a way that they cross natural boundaries for
   their data size.  For example, a diagnostic message is issued if
   /WARNINGS=ALIGNMENT is in effect and the virtual address of a
   REAL(KIND=8) variable is not a multiple of 8.

   The default is /WARNINGS=ALIGNMENT.  To suppress diagnostic
   messages about misaligned data, specify /WARNINGS=NOALIGNMENT.

   To control the alignment of fields in derived-type or record
   structures or in common blocks, use the /ALIGNMENT qualifier.
   (See the HP Fortran for OpenVMS User Manual.)

 [NO]ARGUMENT_CHECKING
   Controls whether the compiler issues diagnostic messages for
   argument mismatches between caller and callee (when compiled
   together).  The default is /WARNINGS=NOARGUMENT_CHECKING.

 [NO]DECLARATIONS
   Controls whether the compiler issues diagnostic messages for any
   untyped data item used in the program.  DECLARATIONS acts as an
   external IMPLICIT NONE declaration.  See the description of the
   IMPLICIT statement in the HP Fortran for OpenVMS Language
   Reference Manual for information about the effects of IMPLICIT
   NONE.

   The default is /WARNINGS=NODECLARATIONS.

 [NO]GENERAL
   Controls whether the compiler issues I-level and W-level
   diagnostic messages.  An I-level message indicates that a correct
   VSI Fortran statement may have unexpected results or contains
   nonstandard syntax or source form.  A W-level message indicates
   that the compiler has detected acceptable, but nonstandard,
   syntax or has performed some corrective action; in either case,
   unexpected results may occur.

   To suppress I-level and W-level diagnostic messages, specify the
   negative form of this qualifier (/WARNINGS=NOGENERAL).

   The default is /WARNINGS=GENERAL.

 [NO]GRANULARITY
   Controls whether the compiler issues the NONGRNACC warning
   message:  "Unable to generate code for requested granularity".

   The default is /WARNINGS=GRANULARITY.

 [NO]IGNORE_LOC
   Controls whether the compiler issues warnings when %LOC is
   stripped from an argument.  The default is
   /WARNINGS=NOIGNORE_LOC.

 [NO]TRUNCATED_SOURCE
   Controls whether the compiler issues a warning diagnostic message
   (EXCCHASRC) when it reads a fixed-form source line with a
   statement field that exceeds the maximum column width.  The
   maximum column width is column 72 or 132, depending on the value
   of the /EXTEND_SOURCE qualifier or the OPTIONS statement option
   in effect.

   This option has no effect on truncation; lines that exceed the
   maximum column width are always truncated.

   The default is /WARNINGS=NOTRUNCATED_SOURCE.

 [NO]UNCALLED
   Controls whether the compiler issues SFUNCALLED messages when a
   statement function is never called.  The default is
   /WARNINGS=UNCALLED (the messages are displayed).

 [NO]UNINITIALIZED
   Controls whether the compiler issues UNINIT messages when a
   variable is used before it has a value assigned to it.  The
   default is /WARNINGS=UNINITIALIZED (the messages are displayed).

 [NO]UNUSED
   Controls whether the compiler issues a warning diagnostic message
   when a variable is declared but not used.  The default is
   /WARNINGS=NOUNUSED.

 [NO]USAGE
   Controls whether the compiler generates informational diagnostic
   messages for questionable programming practices which, though
   allowed, often are the result of programming errors.

   For example, the following would cause such a message:  a
   continued character or Hollerith literal whose first part ends
   before the statement field and appears to end with trailing
   spaces.

   The default is /WARNINGS=USAGE.

 ALL
   Causes the compiler to print all I-level and W-level diagnostic
   messages, including warning messages for any misaligned data and
   untyped data items.  Specifying ALL has the effect of specifying
   (ALIGNMENT, ARGUMENT_CHECKING, DECLARATIONS, GENERAL,
   GRANULARITY, IGNORE_LOC, TRUNCATED_SOURCE, UNCALLED,
   UNINITIALIZED, UNUSED, USAGE).  This is the same as specifying
   /WARNINGS.

 NONE
   Suppresses all I-level and W-level messages.  This is the same as
   specifying /NOWARNINGS.
