347 We need to do this since VMS has the following coding on status codes:
349 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
350 The important thing to know is that odd numbers are considered
351 good, while even ones are considered errors.
352 Bits 3-15: actual status number
353 Bits 16-27: facility number. 0 is considered "unknown"
354 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
355 output the message (which, for random codes, just looks ugly)
357 So, what we do here is to change 0 to 1 to get the default success status,
358 and everything else is shifted up to fit into the status number field, and
359 the status is tagged as an error, which is what is wanted here.
361 Finally, we add the VMS C facility code 0x35a000, because there are some
362 programs, such as Perl, that will reinterpret the code back to something
363 POSIXly. 'man perlvms' explains it further.
365 NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
366 codes (status type = 1). I couldn't disagree more. Fortunately, the
367 status type doesn't seem to bother Perl.
