Controls VMS-specific language features. Currently,
there are four VMS-specific features available: status ($?)
, exit
, time
, and hushed
. If you’re not using VMS, then this
module won’t have any affect.
vmsish is shipped with the Perl 5.8 source kit.
For example, without vmsish, you can’t execute a hushed
version of exit:
$ perl -e"exit 44;" Non-hushed error exit %SYSTEM-F-ABORT, abort DCL message $ show sym $STATUS $STATUS == "%X0000002C"
When you use vmsish, you get . . . nothing!
$ perl -e"use vmsish qw(hushed); exit 44;"
vmsish implements the following options.
status
Causes $?
and system
to return the native VMS exit
status instead of emulating the POSIX exit status.
exit
Causes exit 1
to
produce a successful exit (with status SS$_NORMAL
) instead of emulating Unix
exit()
, which considers
exit 1
as an indication of an
error. As with the CRTL’s exit()
function, exit 0
is also mapped to an exit
status of SS$_NORMAL
, and any
other argument to exit()
is
used directly as Perl’s exit status.
time
Makes all times relative to the local time zone instead of the default Universal Time (a.k.a. Greenwich Mean Time, or GMT).
hushed
Suppresses printing of VMS status messages to SYS$OUTPUT
and SYS$ERROR
if Perl terminates with an
error status and allows programs that are expecting Unix-style
Perl to avoid parsing VMS error messages. It does not supress
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.
