  /* 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.
