76 # of 65535. Codes from 2 through 7 are assumed to be from non-compliant
77 # VMS systems and passed through. Programs written to use _POSIX_EXIT()
78 # codes like GNV will pass the numbers 2 through 255 encoded in the
79 # C facility by multiplying the number by 8 and adding %x35A000 to it.
80 # Perl will decode that number from children back to it's internal status.
82 # For native VMS status codes, success codes are odd numbered, error codes
83 # are even numbered. The 3 LSBs of the code indicate if the success is
84 # an informational message or the severity of the failure.
86 # Because the failure codes for the tests of the CLI facility status codes can
87 # not be translated to UNIX error codes, they will be reported as EVMSERR,
