RE(80 is one day) and RE(tn) is set to 1lnnI'. After that, 5vp(J) moves to normal processing.

Status display and monitoring of CPU (1), input/output device (6
), the system enters a state of waiting for an operator to operate the information processing device.

In this way, power is turned on by writing and registering the PAC'H@TRCK(ffc) VC command string.

Or after the initial micro program load command.

The information processing device can be set to a desired state without operator intervention.

In the above embodiment, a command to set a value in a register in the central processing unit (1) was explained, but since there is only one processing program that processes the command, input from the input/output device (6) PACI(・'I'RCK(tc
) and can be executed continuously after the initial micro program is loaded. Also, the number of commands that can be executed consecutively is limited by the capacity of PACH/TRCK (fc) and 8VP-MEM (4'l), so as long as you increase this capacity, you can increase the number of commands as much as you like. 1 can be executed in various combinations and orders.

The contents of PACI(-TRCK(tc)) can be rewritten, added to, and erased by operations from the input/output device (6).

The operator can reset the desired state of the information processing device after IMPL as appropriate.

In this way, the method of this invention enables the system disk
Flexible disc sheet (g) as a sheet
In addition, PACH@TRCK(gc) is provided, which allows multiple consecutive registrations of any combination of all commands that can be interpreted and executed by SVP(,?), and 5VPC-TRCK(ff&). 8VP-RAM (

Read pAca @TRCK (gc) and read its contents sequentially.

By adding a program to the command interpretation processing program, IMPL(l/
) After that, it is possible to automatically set or change the information processing device to a desired state, or display the state.

Furthermore, in the above embodiment, PACH/TRC after IMPL
I have shown a method that reads K(gc) and executes the registered command, but if you add a command that reads and executes pAc)r -TRCK (g c ) to the 5vp(3) command, Of course, it is possible to replace a complicated setting procedure with seven commands, and also provides multiple types of PACH/TRcx(re) and selects one PACH/TRcx(rc) from among them depending on the conditions. It is also clear that if the SvP microprogram is provided with the function of selecting a path, it will be possible to set and change the state of the information processing device according to various states.

〔Effect of the invention〕

As mentioned above, according to the invention, the external 161J II
By providing a storage auxiliary device with a section that can register a single command for setting and changing the status of an information processing device, and adding a function to the service processor to read and execute the contents of this section, the information processing device can be started up easily. When raising,
Since settings are automatically performed until the desired state is reached, information processing can be brought to the desired state without the need for an operator who is familiar with the device. In addition, even if complicated operation procedures are required, PACT (@TRC
Since hand 1 is registered as a command sequence in K and the operation is automatically performed, there is no startup failure due to an error in the operator 1, and reliability is improved.

Furthermore, when developing or testing an information processing device, it is possible to automatically temporarily set the contents of the control storage unit, or to automatically set a certain state and then run a diagnostic program. The effect is that it can improve the efficiency of trial drawing, etc.
