260 | We need to do this since VMS has the following coding on status codes: | |
511e596b RL |
261 | |
262 | Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ... | |
263 | The important thing to know is that odd numbers are considered | |
0f113f3e | 264 | good, while even ones are considered errors. |
511e596b RL |
265 | Bits 3-15: actual status number |
266 | Bits 16-27: facility number. 0 is considered "unknown" | |
267 | Bits 28-31: control bits. If bit 28 is set, the shell won't try to | |
268 | output the message (which, for random codes, just looks ugly) | |
269 | ||
270 | So, what we do here is to change 0 to 1 to get the default success status, | |
271 | and everything else is shifted up to fit into the status number field, and | |
f625d383 | 272 | the status is tagged as an error, which is what is wanted here. |
c3944a99 RL |
273 | |
274 | Finally, we add the VMS C facility code 0x35a000, because there are some | |
275 | programs, such as Perl, that will reinterpret the code back to something | |
46d08509 | 276 | POSIX. 'man perlvms' explains it further. |
f625d383 | 277 | |
c3944a99 RL |
278 | NOTE: the perlvms manual wants to turn all codes 2 to 255 into success |
279 | codes (status type = 1). I couldn't disagree more. Fortunately, the | |
280 | status type doesn't seem to bother Perl. | |
