INSERT EXTENDED function

Version 2 of c-treeRTG 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 c-treeRTG 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.
