Next, the operation of the above embodiment will be explained.

In FIG. 1, when the third parameter of the command AA, which is the first command constituting the command catalog, is input from the input device 1, the input unit 21 inputs the parameter of the command AA input to the control unit 22. Notify. Upon receiving this notification, the control unit 22 instructs the parameter analysis unit 23 to analyze this parameter. The parameter analysis section 23, which has received the instruction to analyze the parameters, refers to the parameter information section 24 and starts analysis processing. The parameter analysis section 23 first reads the attribute table address a and the command processing address sa of the command AA from the command table 240 of the parameter information section 24 and notifies the control section 22 of them. Next, the parameter analysis unit 23 uses the attribute table address a.
Attribute 1 stored first in the parameter attribute table 24a that can be referenced by , that is, the 1 digit registered as attribute information regarding the first parameter in the attribute column 244 of the parameter information registration section A1 of the parameter attribute table 24a in FIG. The control unit 22 is notified of the decimal number. Next, the parameter analysis unit 23 uses the valid value B1 of the valid value table 246 of FIG. Read. As shown in FIG. 5, the valid value B1 registered at address p1 is information in which the minimum value is 1 and the maximum value is 2,
This is also notified to the control unit 22. Attribute 1 and valid value B1
The control unit 22 that has been notified of the contents of the parameter analysis unit 2
3 to determine whether the first parameter of the input command AA is valid. Upon receiving this, the parameter analysis unit 23 determines that the input value is a valid parameter if the input value is a decimal number between 1 and 2, and notifies the control unit 22 of this fact. The control unit 22, which has received the notification of the determination result, stores the command name AA of the input command in the command name 250 of the command catalog registration unit 25.
The command processing address sa, which has already been notified, is stored in the processing start address 251 of the command catalog registration section 25, and the determination result of the first parameter of the command AA is stored in the first parameter storage section 252.

Next, the parameter analysis section 23 sends the four-character JIS code registered as attribute information regarding the second parameter to the parameter attribute table 24a of the parameter information section 24 in the attribute column 244 of the parameter information registration section A2 to the control section 22. Notify. Next, based on the address p2 registered in the valid value table address column 245 of the parameter information registration section A2 of the parameter attribute table 24a,
Read the valid value B2 of the valid value table 246 in FIG. As shown in FIG. 5, the valid value B2 registered at address p2 is information that if it is a JIS code of ACT△, it will be converted to 0, and if it is a JIS code of INA△, it will be converted to 2 (△ is a symbol representing a blank space),
This is also notified to the control unit 22. Attribute 2 and valid value B2
The control unit 22 that has been notified of the contents of the parameter analysis unit 2
3 to determine whether the second parameter of the input command AA is valid, and upon receiving this, the parameter analysis unit 23 converts the converted 0 or 2 if the parameter is valid. The value of command catalog registration part 2
5 is stored in the second parameter storage unit 253 of command AA.

Next, the parameter analysis section 23 analyzes the third parameter, and the attribute column 2 of the parameter information registration section A3 of the parameter attribute table 24a in FIG.
44, the information that this is the last parameter (E
ND) is registered, this information is also notified to the control unit 22. The control unit 22 causes the parameter analysis unit 23 to make a determination in the same manner as in the case of the first and second parameters, stores the result in the third parameter storage unit of the command AA of the command catalog registration unit 25, and makes the determination regarding the command AA. Finish the process.

[0020] When the processing related to command AA is completed,
Subsequently, processing regarding command BB input from the input device 1 is performed in the same manner, and when that is completed, processing regarding command CC is performed.

In FIG. 1, when an internal interrupt factor 400 of a program to be debugged in the main storage device 4 is executed, the internal interrupt mechanism section 31 of the central processing unit 3 generates an internal interrupt. That is, first, the currently running debug target program 40 is temporarily stopped, and the interrupt processing unit 26
Notify that there has been an interrupt. The interrupt processing unit 26 that has received the notification starts activating the command catalog using the command catalog registration unit 25 via the control unit 22. The interrupt processing unit 26 includes the command catalog registration unit 2
5, information regarding the command AA registered as a command catalog is retrieved, and the command AA processing section 41a stored at address sa of the command processing section program 41 of the main storage device 4 is activated. When the execution of the command AA is finished, the interrupt processing unit 26 subsequently starts the command BB and the command CC, and when the execution of all command catalogs is finished, it reports this to the central processing unit 3. The central processing unit 3 that received the report,
The debug target program 40 that has been temporarily stopped is restarted.

[0022]

[Effects of the Invention] As explained above, the input command parameter analysis device of the present invention has a table in which attributes and valid values are registered for each parameter of all commands in advance, and catalogs are created using the table. By processing the parameter analysis of the commands to be executed all at once, there is no need to analyze the parameters for each command, which has the effect of reducing the program area. Furthermore, since parameters can be analyzed by registering attributes and valid values, there is also the effect that parameters can be easily added or changed. Furthermore,
When executing cataloged commands, parameter analysis can be omitted, which improves processing speed, and also has the effect of detecting parameter errors when inputting commands.
