vmsish
Perl pragma to control VMS-specific language features

vmsish - Perl pragma to control VMS-specific language features


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';

    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'.

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 supresses printing of VMS status messages to SYS$OUTPUT and SYS$ERROR if Perl terminates with an error status. This primarily effects error exits from things like compiler errors or ``standard Perl'' runtime errors, where text error messages are also generated by Perl.

The error exits from inside VMS.C are generally more serious, and are not supressed.

See perlmod/Pragmatic Modules.
