300 | We need to do this since VMS has the following coding on status codes:
|
---|
301 |
|
---|
302 | Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
|
---|
303 | The important thing to know is that odd numbers are considered
|
---|
304 | good, while even ones are considered errors.
|
---|
305 | Bits 3-15: actual status number
|
---|
306 | Bits 16-27: facility number. 0 is considered "unknown"
|
---|
307 | Bits 28-31: control bits. If bit 28 is set, the shell won't try to
|
---|
308 | output the message (which, for random codes, just looks ugly)
|
---|
309 |
|
---|
310 | So, what we do here is to change 0 to 1 to get the default success status,
|
---|
311 | and everything else is shifted up to fit into the status number field, and
|
---|
312 | the status is tagged as an error, which is what is wanted here.
|
---|
313 |
|
---|
314 | Finally, we add the VMS C facility code 0x35a000, because there are some
|
---|
315 | programs, such as Perl, that will reinterpret the code back to something
|
---|
316 | POSIXly. 'man perlvms' explains it further.
|
---|
317 |
|
---|
318 | NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
|
---|
319 | codes (status type = 1). I couldn't disagree more. Fortunately, the
|
---|
320 | status type doesn't seem to bother Perl.
