Issue the bsrtmrge function.
The bsrtmrge function is issued continuously from PowerBSORT to the notification of the end of the record. In the bsrtmrge function in this form, there are 2 functions: one passes records from the user application to PowerBSORT and the other one receives records from PowerBSORT. In issuing the bsrtmrge function, the record of individual string (record group that have been sorted) is passed and the records to be returned from PowerBSORT are received. When the end of the record is notified to all the strings in process, bsrtmrge function is issued continuously until the end of the record is notified even if there is no record to be passed and the record to be returned from PowerBSORT is received.
The bsrtclse function is issued at the end if the end of the record is notified from PowerBSORT.
