I think the limit was 32767 (077777). But yep, it maintained the number of copies you specified and then would purge the oldest so you only kept that many. Every save resulted in a new file with an incremented value. There was a hardlink of the name w/o a version that pointed to the highest version so if you specified the name without a version you got the most recent.
I don't recall a lot of files in VMS though that you would open and update the file directly and not end up writing a new file. There were some instances of it and those didn't increment. The latest version of Borland Builder (actually called Borland Developer Studio 2006) does this for all files maintained in the IDE. Very cool for rollback. 01/12/2006 11:26 PM 8,236 TControllerThreadUnit1.cpp.~74~ 01/12/2006 11:26 PM 8,236 TControllerThreadUnit1.cpp.~75~ 01/12/2006 11:27 PM 8,234 TControllerThreadUnit1.cpp.~76~ 01/12/2006 11:27 PM 8,235 TControllerThreadUnit1.cpp.~77~ 01/12/2006 11:28 PM 8,228 TControllerThreadUnit1.cpp.~78~ 01/12/2006 11:34 PM 8,257 TControllerThreadUnit1.cpp.~79~ Going back to my mindset when playing with that stuff, it was pretty sweet. :o) Hey Brett, you should go find VMS or OpenVMS and play with it. Who knows what kind of ideas could come of it. I heard a rumour that some of the other NT stuff has a VMS background... <snicker> Long live Digital Equipment Technology people. ;o) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Al Lilianstrom Sent: Friday, January 13, 2006 3:55 PM To: [email protected] Subject: Re: [ActiveDir] OT: DEC 2006 (way OT ...)

Could you elaborate how it worked? It's a simple thing. You edit a file and when you save the file a new version of the file was created in the same directory. Say you edited login.com (in VMS this is not a binary) for the first time and saved your changes the directory would look something like this: LOGIN.COM;2 time/date stamp LOGIN.COM;1 ... Unless you have file version limits set or manually purged one could have up to 32768 copies of the file. It did chew up space but made rolling back bad command procedures really easy. It did cause problems on occasion but was very handy. Oh - lexical functions would be nice too. al > Cheers, > BrettSh [msft] > SDE - ESE > > > On Thu, 12 Jan 2006, Al Lilianstrom wrote: > >> Don't forget the VAXMate and PCSA v1.1.
