Thanks to all who responded. I decided to save a copy of the log (always a smart move, I think), and hen did the search (F8) for UPL CNFM marked Y, then to QSO|Multiple QSOs Operation|Set Confirmed Flag|Yes.
Worked like a champ, which is usual, it seems with DX4WIN. Incidentally, one gent, Dick Flanagan, pointed out that have both flags set would make it more difficult to determine which confirmed QSOs were only on cards and/or which were only on LOTW. He's absolutely correct, of course, so when I saved the log prior to the global confirmed routine, I made two copies: one on the flash drive for the log as it was prior to the operation and, one which is in a file marked "dx4win UNTOUCHABLE" (for obvious reasons). I found that there appears to be no difference in the DXCC report from the log after doing the global confirmed operation, so I'll probably go to the "untouchable" file, and save it back into the "SAVE" directory as K1KOlog after changing the current one to another name: oldK1KOlog, or something equally innovative. Thanks VERY much for all the help. Very 73, Karl, K1KO Virginia Beach, VA
