|
|---|
| 310 |
|
|---|
| 311 | Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
|
|---|
| 312 | The important thing to know is that odd numbers are considered
|
|---|
| 313 | good, while even ones are considered errors.
|
|---|
| 314 | Bits 3-15: actual status number
|
|---|
| 315 | Bits 16-27: facility number. 0 is considered "unknown"
|
|---|
| 316 | Bits 28-31: control bits. If bit 28 is set, the shell won't try to
|
|---|
| 317 | output the message (which, for random codes, just looks ugly)
|
|---|
| 318 |
|
|---|
| 319 | So, what we do here is to change 0 to 1 to get the default success status,
|
|---|
| 320 | and everything else is shifted up to fit into the status number field, and
|
|---|
| 321 | the status is tagged as an error, which is what is wanted here.
|
|---|
| 322 |
|
|---|
| 323 | Finally, we add the VMS C facility code 0x35a000, because there are some
|
|---|
| 324 | programs, such as Perl, that will reinterpret the code back to something
|
|---|
| 325 | POSIXly. 'man perlvms' explains it further.
|
|---|
| 326 |
|
|---|
| 327 | NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
|
|---|
| 328 | codes (status type = 1). I couldn't disagree more. Fortunately, the
|
|---|
| 329 | status type doesn't seem to bother Perl.
