215 | We need to do this since VMS has the following coding on status codes: |
216 | |
217 | Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ... |
218 | The important thing to know is that odd numbers are considered |
219 | good, while even ones are considered errors. |
220 | Bits 3-15: actual status number |
221 | Bits 16-27: facility number. 0 is considered "unknown" |
222 | Bits 28-31: control bits. If bit 28 is set, the shell won't try to |
223 | output the message (which, for random codes, just looks ugly) |
224 | |
225 | So, what we do here is to change 0 to 1 to get the default success status, |
226 | and everything else is shifted up to fit into the status number field, and |
227 | the status is tagged as an error, which is what is wanted here. |
228 | |
229 | Finally, we add the VMS C facility code 0x35a000, because there are some |
230 | programs, such as Perl, that will reinterpret the code back to something |
231 | POSIX. 'man perlvms' explains it further. |
232 | |
233 | NOTE: the perlvms manual wants to turn all codes 2 to 255 into success |
234 | codes (status type = 1). I couldn't disagree more. Fortunately, the |
235 | status type doesn't seem to bother Perl. |
