File Comment DOS DO-ONCE v2.30 This program was designed to help take care of some "regular" chores. Ones which I usually performed either once a day (optimizing my disk), once a week (using TIMESET to call the Naval Observatory Clock and set the time on my computer), or once a month (using SpinRite to renew the low-level format of my hard disk) . No matter how many times during that particular day I booted my computer. Last revision date in archive: 02-16-95.
