	As I understand the SysEnvirons call (don't have my IM in front of me
so I am doing this from memory).  It takes the record itself and then fills it
in based on the version number that you pass it.  I believe that if you ask for
version 2 and there is only a version 1 that you will get version 1, but if you
ask for version 1 and there is a version 2 it does not give you version 2.
