I don't really expect that there will be Y2K problems on versions of VMS 
older than V5.5-2.  OTOH, the older versions were not put through the 
exhaustive testing that V5.5-2 and later received.  If anyone DOES 
encounter Y2K problems with with versions prior to V5.5-2 they are 
unlikely to get either sympathy or a fix.
