73 | # On VMS, successful returns from system() are reported 0, VMS errors that |
74 | # can not be translated to UNIX are reported as EVMSERR, which has a value |
75 | # of 65535. Codes from 2 through 7 are assumed to be from non-compliant |
76 | # VMS systems and passed through. Programs written to use _POSIX_EXIT() |
77 | # codes like GNV will pass the numbers 2 through 255 encoded in the |
78 | # C facility by multiplying the number by 8 and adding %x35A000 to it. |
79 | # Perl will decode that number from children back to it's internal status. |
80 | # |
81 | # For native VMS status codes, success codes are odd numbered, error codes |
82 | # are even numbered. The 3 LSBs of the code indicate if the success is |
83 | # an informational message or the severity of the failure. |
84 | # |
85 | # Because the failure codes for the tests of the CLI facility status codes can |
86 | # not be translated to UNIX error codes, they will be reported as EVMSERR, |
87 | # even though Perl will exit with them having the VMS status codes. |
88 | # |

90 | # DCL EXIT statement. |
