Abstract

PURPOSE:To input a command by substituting a parameter, constituting part of a command character string giving an instruction to a program of an electronic computer, with a simple symbol. CONSTITUTION:The command parameter substitution system consists of a substitute parameter storage means 11 which stores simple symbols for giving substitution instructions and parameters in a parameter correspondence file 13 so that they correspond to each other and a parameter substituting means 12 which substitutes the simple symbols with the parameters by referring to the parameter correspondence file 13, and a user inputs the command character string which is described partially in symbols; and the symbols in the command character string are substituted with the prepared parameters corresponding to the symbols and then passed to the program 3. Consequently, misinput of the command character string caused when the user inputs a complicate and long command is reducible.

A substitution parameter storage means 11 for storing in the parameter correspondence file 13 a parameter obtained in advance using the input device 6 and a substitution instruction symbol obtained by symbolizing this parameter;
Input device 5 used by connecting to command analysis function a2a
According to the command analysis function a2a, the parameter substitution means 12 is provided for converting the substitution instruction symbol in the command character string registered in the command buffer 4 into a parameter.

The parameter replacing means 12 is the program 3
The command analysis function a2a, to which control is passed from the command buffer 4 for the command character string input from the input device 5,
If the replacement instruction symbol is included in the command character string stored in the command buffer 4 after the storage of the parameter, the parameter correspondence file 13 is searched using this substitution instruction symbol as a key. If the substitution instruction symbol is stored in the parameter correspondence file 13, the substitution instruction symbol in the command character string stored in the command buffer 4 is replaced with the parameter corresponding to the substitution instruction symbol. Further, when the replacement instruction symbol is not stored in the parameter correspondence file 13, the parameters of the command buffer 4 remain unchanged. Then, the program 3 refers to the command character string in the command buffer 4 and executes the instruction.

The parameter correspondence file 13 will be briefly described with reference to FIGS. 2 and 3.

2 and 3, in the parameter correspondence file 13, a substitution instruction symbol and a parameter corresponding to this substitution instruction symbol are combined as shown in the configuration example of FIG. Is stored. This record is called a replacement instruction record and is stored by the replacement parameter storage means 11.

Next, a specific example of the replacement instruction record will be briefly described with reference to FIG.

In FIG. 4, "%" in the replacement instruction record
“A” is a substitution instruction symbol, which is represented by an alphanumeric symbol with “%” at the beginning, and “XYZ” is a parameter corresponding to “% A”.

Next, referring to FIG. 5, the command buffer 4

Is opened (step 21). Next, the substitution instruction symbol and the parameter corresponding to this substitution instruction symbol are input from the input device 6 (step 22). A simple check such as double registration of the replacement instruction symbol and the parameter input here is performed (step 23), and if there is no contradiction (step 2)
4, No), the replacement instruction record shown in FIG. 3 is created (step 25) and stored in the parameter correspondence file 13 (step 26). If there is a contradiction (step 24, Yes), an error message is output (step 27) and is not stored in the parameter correspondence file 13. After that, these processes are repeated (step 28, N
o) If the storage is completed (step 28, Ye)
s), the parameter correspondence file 13 is closed (step 29), and the replacement parameter storage means 11 is terminated.

Next, an example of the operation of the parameter replacing means 12 of the command parameter replacing method 1 of this embodiment will be described with reference to FIG.

In FIG. 7, the command analysis function a2a
However, after the command character string input from the input device 5 is stored in the command buffer 4 and the parameter replacing means 12 is activated, the parameter corresponding file 13 is first opened (step 31). Next command buffer 4
Parameter of each parameter is read (step 3
2) The process is passed to the following process, and the following process is repeated until there are no parameters in the command buffer 4 (step 3).
3, No).

If the parameter read by this processing is the substitution instruction symbol (step 34, Yes),
The replacement instruction record of the parameter corresponding file is read (step 35), and if the replacement instruction symbol of the command buffer 4 matches (step 36, No, step 37, Ye).
s), the replacement instruction symbol of the command buffer 4 is replaced with the parameter (step 38), and if they do not match (step 36, No, step 37, No), until they match or until there is no replacement instruction record (step 36, Ye
s) Read the parameter corresponding file (step 35),
This process is repeated. If the replacement instruction symbol of the replacement instruction record that matches the replacement instruction symbol of the command buffer 4 does not exist in the parameter correspondence file 13, the parameter of the command buffer 4 remains unchanged. And
If there are no more parameters in the command buffer 4 (step 33, Yes), the parameter correspondence file 1
3 is closed (step 39), the parameter replacing means 12 is exited, and control is returned to the command analysis function a2a.
