COMMIT Statement

The COMMIT statement unlocks locked records and flushes buffers to disk.

General Format:

COMMIT.

General Rules:

1. The COMMIT statement causes unwritten file buffers to be written to the target file.
2. After writing file buffers, the COMMIT statement releases record and file locks held by the target file.
