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