Brings back memories. If I recall correctly, when you had this turned on, files would get a hidden extension of .1 .2 .3 etc. And you could specify how many revisions to keep around? I also recall on our system, most of the time this was turned off because disk space was so precious. But I do recall this feature saving my bacon a time or two...
- atsaloli 10y agoYep! It goes up to 32k by default, but you can limit it: "The /VERSION_LIMIT qualifier for the CREATE/DIRECTORY, SET DIRECTORY, and SET FILE commands lets you control the number of versions of a file. If you exceed the version limit, the system automatically purges the lowest version file in excess of the limit. For example, if the version limit is 5 and you create the sixth version of a file (ACCOUNTS.DAT;6), the system deletes the first version of the file (ACCOUNTS.DAT;1). To view the version limit on a file, enter the DIRECTORY/FULL command. The version limit is listed in the File attributes: field."

I thoroughly enjoyed using DCL (Digital Command Line -- the VMS shell) and VMS (with the wall of documentation, like http://www.pkl.net/~matt/photos/machines/tn/pict0157.jpg.html http://www.pkl.net/~matt/photos/machines/tn/pict0157.jpg.htm...). It always felt structured and orderly, unlike UNIX systems, which are more "organic". :) (I love UNIX too!)
- DonaldFisk 10y agoThis wasn't unique to VMS. Symbolics Genera had this capability. ITS, VME-B, and I think TOPS-10, also had numbered file versions.
- atsaloli 10y agoFair enough. My computing career started in the nineties on VMS at the Help Desk of Brandeis University, my work-study job.
