out of date.

COMMITTRANS commits a pending transaction (a series of ISAM database
operations).
COMMITTRANS
Usage Notes
■ Transactions are a way to group a series of ISAM operations so that
you can commit them as a whole, rescind them all, or rescind
operations since a designated savepoint.
■ Use BEGINTRANS to indicate the beginning of a transaction.
■ Use SAVEPOINT to designate a savepoint.
■ Use ROLLBACK and ROLLBACK ALL to rescind all or part of a transaction's
operations.
■ If there is no transaction pending, BASIC generates the error
message, "Illegal function call."
■ COMMITTRANS commits only ISAM operations. It does not affect other
BASIC variables or file types.
Programming Tips
■ Any ISAM operation that closes a table causes transactions to be
committed. For example, if a type mismatch occurs while you are
opening an ISAM table, the table is closed and a pending transaction
is committed.
■ You may wish to code your programs so they first open all tables,
then perform all transactions, then close tables. Make sure any
operation that can close a table occurs outside a transaction.
