"FOO.TXT;" is just shorthand for "FOO.TXT;0". It's also legal to say "FOO.TXT;-1" meaning the previous version (i.e. most recent -1), as is ";-2", ";-3", etc. It's legal ";-0" too, meaning the oldest version available :) Actually, in VMS (as well as in RSX), ;-1 means the oldest version available. Around here is where VMS differs from TOPS-20. ;0 also have different meanings on TOPS-20 compared to VMS. On VMS, ;0 means the most recent version if you open a file for reading. But if you try to create a file, ;0 means one higher than what exist right now. In TOPS-20, unless my memory fails me, ;0 will overwrite the most recent version that do exist. The ;-0, ;-1, ;-2, ;-3 and so on to refer to older versions is how I think TOPS-20 did it. I don't remember that there is a way of specifying something like that in VMS. I think you only have ;-1 and ;0 which are special. But I might be remembering wrong from playing too much with RSX. :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
