The value of COMMIT_COUNT indicates the conditions under which you want to issue an automatic COMMIT_WORK operation.
Examples
1) COMMIT_COUNT 0
A commit is issued when no locks are held, either because all files that had locked records have been closed, or because a COBOL COMMIT verb has been issued. This is the default value.
2) COMMIT_COUNT n
A commit is issued after n operations. WRITE, REWRITE, and DELETE count towards n; READ, START, and READ NEXT do not.
3) COMMIT_COUNT -1
No commit is issued by the Acu4GL product. When COMMIT_COUNT is set to "-1", there are two alternate ways to perform a commit or rollback.
One way is to call sql.acu with COMMIT WORK or ROLLBACK WORK.
The second way is to use the COBOL verbs COMMIT and ROLLBACK, available in ACUCOBOL-GT.
COMMIT_COUNT is set to "-1" internally when you use the transaction management facilities available in the ACUCOBOL-GT compiler.
A COMMIT WORK, however, is issued on exit from the runtime (for example, on execution of a STOP RUN).
