103 # VMS systems and passed through. Programs written to use _POSIX_EXIT()
104 # codes like GNV will pass the numbers 2 through 255 encoded in the
105 # C facility by multiplying the number by 8 and adding %x35A000 to it.
106 # Perl will decode that number from children back to it's internal status.
108 # For native VMS status codes, success codes are odd numbered, error codes
109 # are even numbered. The 3 LSBs of the code indicate if the success is
110 # an informational message or the severity of the failure.
112 # Because the failure codes for the tests of the CLI facility status codes can
113 # not be translated to UNIX error codes, they will be reported as EVMSERR,
