tion Control Unit using the IORD instruction.
• If error code 8700 already exists, the 8700 error codes will be cleared and
the operation will end.
• If any other error code exists, none of the current error codes will be
changed and the operation will end.
If an IORD format error (8700) occurs when IORD is executed, the 8700 error
