Checking my CP/M Plus manual, it is indeed the length in bytes (module 128). Thus, a value of "00" means the sector is full. In fact, that is the default because it is up to the application to set this value. There are FEW programs which worry or care about the length of the last sector in CP/M since there was never this mechanism in CP/M 2.2 which is still the mainstay (or clone-stay) of CP/M these days. Unless you are strictly in CP/M+ land and ALL of your applications know it, use of this byte is of no help. -Mitch
