The naming scheme used is surely known to analog via the LOGFILE statement ? And is surely effectively the same thing as the rotation schedule ? Eg LOGFILE sys$disk:[]access_log_combined_%Y-%M-%D.gz;* would be daily files, from midnight - if they were anything else analog's access to them would already be broken. LOGFILE sys$disk:[]services-%Y-%M.log-gz would be monthly from 00:00 on the 1st. If you generate the logfile name from the template for the from time, and loop round until you get to the to time, you've got all the logs. Your loop step would be determined by which date/time components you found in the LOGFILE statement(s). Overlap could be an issue: you might need an overlap statement, saying how much overlap you cater for. Might be from 0 to a few seconds, I suppose, dependent on your longest request. 0 would probably be good enough for most purposes. Multiple logfiles and the like - would still be allowed as at present by use of OS-dependant wildcards (as in my first example).
