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