As in "FOO.TXT;" ? That certainly *used* to be a valid filename, back in V4/V5 days anyway, That's legal. The longer story is that version numbers start with 1, and ";0" is shorthand for the most recent version. "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. And, FWIW, it's also legal to use angle brackets in VMS path specifications (e.g. "DISK:<DIR.DIR.DIR>FOO.TXT"). Both the use of angle brackets and using a second "." in place of the semicolon (e.g. "FOO.TXT.1") were put into VMS long ago as an aid to ex-TOPS20 users. Bob
