231 | We need to do this since VMS has the following coding on status codes: | |
511e596b RL |
232 | |
233 | Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ... | |
234 | The important thing to know is that odd numbers are considered | |
0f113f3e | 235 | good, while even ones are considered errors. |
511e596b RL |
236 | Bits 3-15: actual status number |
237 | Bits 16-27: facility number. 0 is considered "unknown" | |
238 | Bits 28-31: control bits. If bit 28 is set, the shell won't try to | |
239 | output the message (which, for random codes, just looks ugly) | |
240 | ||
241 | So, what we do here is to change 0 to 1 to get the default success status, | |
242 | and everything else is shifted up to fit into the status number field, and | |
f625d383 | 243 | the status is tagged as an error, which is what is wanted here. |
c3944a99 RL |
244 | |
245 | Finally, we add the VMS C facility code 0x35a000, because there are some | |
246 | programs, such as Perl, that will reinterpret the code back to something | |
46d08509 | 247 | POSIX. 'man perlvms' explains it further. |
f625d383 | 248 | |
c3944a99 RL |
249 | NOTE: the perlvms manual wants to turn all codes 2 to 255 into success |
250 | codes (status type = 1). I couldn't disagree more. Fortunately, the | |
251 | status type doesn't seem to bother Perl. | |
