Apologies to all who don't care about VMS and file version numbers.. OK, no more vague memories. I got my old VAX 4000 powered up, and three amazing things happened:
1) The VAX booted even though it had been gathering dust for 10 years. 2) I remembered the SYSTEM password, and my password too! 3) VMS 5.5-2 was Y2K ready in 1992, taking today's date with no problem.
I fiddled around a bit with VMS, and it looks like the following command set things up for me so that I only have one version for any new files I create:
SET DIRECTORY/VERSION_LIMIT=1 SYS$SYSDEVICE:[USERS.STEVEN]
This change was persistant across logins. Hope this helps.
