The Offset for this flag is record-length, and flag : length is 1. Is This flag maintained by C-ISAM and when, how? The flag byte and the entire record i zero'ed out when the record is deleted. When a record is inserted the flag byte is a 0x0a. This makes the dat file just a flat file. Glen Johnson
