This keyword specifies one of three record locking modes supported by the runtime. The default locking mode is LOGICAL. The three modes are defined as follows:

 

Mode

Definition

LOGICAL

All records located in the 0 to 2GB range are actually locked in the 2GB to 4GB range.

PHYSICAL

All records located in the 0 to 0x80000000 range are locked in the 0 to 0x80000000 range. This mode is intended to provide compatible record locking ranges when accessing files on Linux platforms. It should be noted that Linux OS environments have a record locking limitation of 2GB that limits the range for which FILEPI can cover.

EXTENDED

All records located in the 0 to 4GB range are locked in the 2GB x 4GB range. This mode uses the Windows 64 bit record locking ranges.
