[Explanation of Table (Figure 2)] Figure 2 (a) shows the structure of the message information table in the EEPROM 9 in this embodiment. It consists of a message number 9a, a level 9b, and a message content 9c. This table stores message information that is sometimes displayed on the CRT 6. Next, FIG. 2(b) shows a processing program name storage area 9d that stores the processing program name corresponding to each processing program when the processing program is executed.

Note that the message number 9a is a number for managing processing program loading errors, various errors during execution, etc.
When an abnormality occurs, processing such as display output is performed using this message number 9a.

Level 9b indicates how to handle the message information, and is used, for example, to determine whether it is a warning error or a fatal error.

[Description of Processing Procedures (FIGS. 3 to 5)] Next, the system program replacement operation in this embodiment will be described below with reference to the flowchart in FIG.

In the key input waiting routine that waits for a key input from the keyboard 5, when a key input is received from the keyboard 5,
The command routine processing shown in FIG. 3 is executed.

First, in step S1, a command input from the keychain 5 is determined, and if it is not a program replacement command, a process corresponding to the input command is performed in step S3.

However, if it is a program replacement command, in step S2, the magnetic disk 7 and floppy disk 8 are searched using the command parameter inputted from the keyboard 5 as the processing program name. Then, in step S4, the search result is determined, and if it is not found, an error display process is performed in step S5,
The process returns to the key input waiting routine from the keyboard 5.

If the specified file exists, step S6
In step S7, the load program in the ROM 3 is activated, and in step S7, the processing program corresponding to the processing program name is loaded. In step S8, it is determined whether or not the loading process in step S7 has ended normally. If an error is detected, error display processing is performed in step Sll, and abnormal termination processing is performed in step S12 and the process is stopped. do. On the other hand, if the loading process has ended normally, control is passed to the loaded processing program in step S9. In step SIO, the processing program name corresponding to the loaded processing program is set to EEFR.
It is stored in the processing program name storage area 9d of the OM9, and the processing program replacement process is completed.

Next, with reference to the flowchart of FIG. 4, the processing after inputting a command for reset designation (cancellation of processing) will be described.

First, in step S13, a command input from the keyboard 5 is determined, and if it is not a reset designation command, a process corresponding to the input command is performed in step S14. In the case of a reset specification command, step S
In step S15, reset processing is performed, and in step S16, the CRT6 is reset.
The message information displayed is recorded on the magnetic disk device 7 or floppy disk 8. The processing program name 9d shown in FIG. 2(b) is added to the Mk message information in the message number 9a shown in FIG. 2(a) as additional information.
