<p>PURPOSE:To manage easily an error output, and to process quickly an abnormality by branching to an error output program and executing an error output routine, when a CPU has detected an error in a program. CONSTITUTION:When each sub-program implementer implements a program which requires an error output, he designates an error message N0 by referring to an error message list. When a CPU 1 detects a CALL.ERR in a program, it branches to an error output program stored in a storage part 2 and executes an error output routine. In this program, an error message is stored in an error message storage part 3 from an error message file device 5 by referring to an index part from ERRN0, and outputted to a designated terminal equipment. In case when a console control device 8 is connected to a channel device, the CPU 1 starts it, the channel device reads the error message, delivers it to the device 8 and displays it.</p> |
