267 /* We need to do this since VMS has the following coding on status codes:
269 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
270 The important thing to know is that odd numbers are considered
271 good, while even ones are considered errors.
272 Bits 3-15: actual status number
273 Bits 16-27: facility number. 0 is considered "unknown"
274 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
275 output the message (which, for random codes, just looks ugly)
277 So, what we do here is to change 0 to 1 to get the default success status,
278 and everything else is shifted up to fit into the status number field, and
279 the status is tagged as an error, which I believe is what is wanted here.
