      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.
