It does not have to just be an endless sink of disk space. On Twenex systems, for example, a maximum number of generations count is maintained. Endless versions of files only exist if you feel a need for it. The count can be set to one if you wish to be risky. In a typical edit-compile-run session you end up with a large generation number, but only two or three back copies of the program. System daemons can hunt around for people with excess versions and can warn them. It could event delete them if disk space is really tight. Finally, disk space is getting cheaper every day. For 10 grand you can add 500 megabytes to your system. Does anyone know if a unix system that has been hacked to have multiple versions? It would also be nice to have an unremove command... -- David Siegel Usenet: mit-eddie!mit-hermes!dms The MIT AI Laboratory Arpa: dms@mit-hermes.arpa Cambridge, MA 02139
