      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.

+     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.
