213 /*-
214 We need to do this since VMS has the following coding on status codes:
511e596b
RL
215
216 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
217 The important thing to know is that odd numbers are considered
0f113f3e 218 good, while even ones are considered errors.
511e596b
RL
219 Bits 3-15: actual status number
220 Bits 16-27: facility number. 0 is considered "unknown"
221 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
222 output the message (which, for random codes, just looks ugly)
223
224 So, what we do here is to change 0 to 1 to get the default success status,
225 and everything else is shifted up to fit into the status number field, and
f625d383 226 the status is tagged as an error, which is what is wanted here.
c3944a99
RL
227
228 Finally, we add the VMS C facility code 0x35a000, because there are some
229 programs, such as Perl, that will reinterpret the code back to something
46d08509 230 POSIX. 'man perlvms' explains it further.
f625d383 231
c3944a99
RL
232 NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
233 codes (status type = 1). I couldn't disagree more. Fortunately, the
234 status type doesn't seem to bother Perl.
