IBMBRIO*

IBMBRIO is the Record I/O Interface module. It is an interface between the record I/O transmitter modules and the calling program. It also loads record I/O error modules.

It has four entry points

  • IBMBRIOA - checks the validity of the I/O statement and calls the transmitter.

  • IBMBRIOB - loads a record I/O error module and branches to it.

  • IBMBRIOC - raises the error condition for invalid statements.

  • IBMBRIOD - raises the appropriate I/O error condition when I/O is in use.
