The ROLLBACK Statement

General Format


*

General Rules

  1. Execution of the ROLLBACK statement causes all record locks in all files held by the run unit to be released.
  2. The file lock on an exclusive file is not affected by the ROLLBACK statement.
  3. If your COBOL system supports the WITH ROLLBACK clause of the SELECT statement as other than documentary, then the ROLLBACK verb:
    1. Indicates completion of the current transaction
    2. Ensures all changes applied during the transaction are canceled.
