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