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