Hello. I was wondering if the meaning or translation of the control codes in columns 81-100 (far right) of the list file are documented somewhere? I reviewed the release notes for 1.8b and the listowner manual (Oct 3, 1995 rev.) and see that the format of the codes in these columns were updated in 1.8b -- but can't find what the codes mean. While I've been finding the QUERY ... WITH <option>(s) command very useful for reviewing subscriber settings, I was just curious about what the codes to the far right now mean. Part of what is prompting this question is that, under 1.8a, I seem to recall coding in the far right-hand columns that would give the approximate timeframe for when a subscriber signed on to list? (am I remembering this correctly? it's been a while since we updated to 1.8b ...). Now that timeframe reference appears to be gone with the new coding? Under 1.8b, is there a way to find out when a subscriber first signed on to the list? Any help, insights, or pointers to appropriate documentation would be much appreciated.
