Version 2 of FairCom RTG BTRV Edition introduces support for the BTRV INSERT EXTENDED (BTRV opcode 40) function. The implementation follows all the BTRV specifications including returning the 4-byte record position of successfully inserted records.
This feature provides functionality beyond the specifications: The file can be opened with keyBuffer bias ‑120, which instructs FairCom RTG BTRV Edition to return 8-byte record positions. In this case, the INSERT EXTENDED function returns the 8-byte record positions instead of 4-byte.
