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.
the status is tagged as an error, which is what is wanted here.
Finally, we add the VMS C facility code 0x35a000, because there are some
programs, such as Perl, that will reinterpret the code back to something
POSIXly. 'man perlvms' explains it further.
NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
codes (status type = 1). I couldn't disagree more. Fortunately, the
status type doesn't seem to bother Perl.
