Type: Boolean

true if the record was modified; otherwise, false.

If you omit this optional return value and if the record cannot be found, a run-time error occurs. If you include the return value, you must handle any errors.

Select the record that you want to replace by using the primary key fields. The record's current key and filters do not affect the operation.

In multi-user environments, another application could modify the record between the time you read the record and when you attempt to modify it. The C/SIDE Database Management System (DBMS) automatically watches for this and, if a conflict occurs, cancels the MODIFY function and displays an error message.

This function works the same as the MODIFY Function (Record).
