## NAME
    vmsish - Perl pragma to control VMS-specific language features

## SYNOPSIS
        use vmsish;

        use vmsish 'status';        # or '$?'
        use vmsish 'exit';
        use vmsish 'time';

        use vmsish 'hushed';
        no vmsish 'hushed';
        [vmsish::hushed](https://www.chedong.com/phpMan.php/perldoc/vmsish%3A%3Ahushed/markdown)($hush);

        use vmsish;
        no vmsish 'time';

## DESCRIPTION
    If no import list is supplied, all possible VMS-specific features are assumed. Currently, there
    are four VMS-specific features available: 'status' (a.k.a '$?'), 'exit', 'time' and 'hushed'.

    If you're not running VMS, this module does nothing.

    "vmsish status"
          This makes $? and "system" return the native VMS exit status instead of emulating the
          POSIX exit status.

    "vmsish exit"
          This makes "exit 1" produce a successful exit (with status SS$_NORMAL), instead of
          emulating UNIX exit(), which considers "exit 1" to indicate an error. As with the CRTL's
          exit() function, "exit 0" is also mapped to an exit status of SS$_NORMAL, and any other
          argument to exit() is used directly as Perl's exit status.

    "vmsish time"
          This makes all times relative to the local time zone, instead of the default of Universal
          Time (a.k.a Greenwich Mean Time, or GMT).

    "vmsish hushed"
          This suppresses printing of VMS status messages to SYS$OUTPUT and SYS$ERROR if Perl
          terminates with an error status, and allows programs that are expecting "unix-style" Perl
          to avoid having to parse VMS error messages. It does not suppress any messages from Perl
          itself, just the messages generated by DCL after Perl exits. The DCL symbol $STATUS will
          still have the termination status, but with a high-order bit set:

          EXAMPLE: $ perl -e"exit 44;" Non-hushed error exit %SYSTEM-F-ABORT, abort DCL message $
          show sym $STATUS $STATUS == "%X0000002C"

              $ perl -e"use vmsish qw(hushed); exit 44;"   Hushed error exit
              $ show sym $STATUS
                $STATUS == "%X1000002C"

          The 'hushed' flag has a global scope during compilation: the exit() or die() commands that
          are compiled after 'vmsish hushed' will be hushed when they are executed. Doing a "no
          vmsish 'hushed'" turns off the hushed flag.

          The status of the hushed flag also affects output of VMS error messages from compilation
          errors. Again, you still get the Perl error message (and the code in $STATUS)

          EXAMPLE: use vmsish 'hushed'; # turn on hushed flag use Carp; # Carp compiled hushed exit
          44; # will be hushed croak('I die'); # will be hushed no vmsish 'hushed'; # turn off
          hushed flag exit 44; # will not be hushed croak('I die2'): # WILL be hushed, croak was
          compiled hushed

          You can also control the 'hushed' flag at run-time, using the built-in routine
          [vmsish::hushed](https://www.chedong.com/phpMan.php/perldoc/vmsish%3A%3Ahushed/markdown)(). Without argument, it returns the hushed status. Since [vmsish::hushed](https://www.chedong.com/phpMan.php/perldoc/vmsish%3A%3Ahushed/markdown) is
          built-in, you do not need to "use vmsish" to call it.

          EXAMPLE: if ($quiet_exit) { vmsish::[hushed(1)](https://www.chedong.com/phpMan.php/man/hushed/1/markdown); } print "Sssshhhh...I'm hushed...\n" if
          [vmsish::hushed](https://www.chedong.com/phpMan.php/perldoc/vmsish%3A%3Ahushed/markdown)(); exit 44;

          Note that an exit() or die() that is compiled 'hushed' because of "use vmsish" is not
          un-hushed by calling vmsish::[hushed(0)](https://www.chedong.com/phpMan.php/man/hushed/0/markdown) at runtime.

          The messages from error exits from inside the Perl core are generally more serious, and
          are not suppressed.
