Abstract

PURPOSE:To ensure the uniform maintenance characteristic of a program which varies by experiences and to improve the productivity in regard of a decision table input device. CONSTITUTION:The processing instruction given to a decision table input device is processed by an instruction input means 1.1, and the type of instruction is decided by an instruction deciding means 1.2. An evolving position designating means 1.3 defines the relationship between a normal processing procedure and the definition information on a decision table to a designating instruction of the evolving position. An editing deciding means 1.4 divides the editing instructions into a normal text editing instructions, a row-based inserting instruction and a deletion editing instruction. Then a definition information input means 1.6, a row inserting means 1.7 and a row deleting means 1.8 carry out the corresponding processings respectively. Finally, a definition information output means 1.5 registers the edited definition information in a designated storing part. Furthermore a processing procedure generating means 1.9 converts the defined decision table into a text form.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device in the form of a decision table.

[0002]

2. Description of the Related Art A conventional decision table input device is
Input in the same area as any programming description and design as any programming.

[0003]

In the above-mentioned conventional programming description, since the decision table is only input as an arbitrary code, there is a drawback that the maintainability at the time of coding tracing due to debugging changes depending on the experience of the coder. is there.

[0004]

A decision table input device according to the present invention includes a conditional description area for storing a description of a conditional expression for controlling execution of a program, a determination instruction area for storing a judgment of the conditional expression, It is composed of four areas, that is, an operation instruction area that stores a description of an operation instruction that determines an instruction statement to be executed from a determination result, and an operation area that stores a description of an instruction statement whose execution is controlled by the operation instruction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 showing a flow chart of an embodiment of the present invention, first, a processing instruction is input by an instruction input means 1.
1, and the instruction determination means 1.2 determines the type of instruction. There are three types of instructions, that is, an instruction for designating a development position, an instruction for editing, and an instruction for ending.

In response to the first instruction for designating the expansion position, the expansion position specifying means 1.3 defines the relation between the normal processing procedure and the definition information of the decision table by the device of the present invention. For the second editing instruction, the editing judgment means 1.4
, But further divides it into three types of detailed instruction information. This editing judgment means 1.4 divides into a normal text editing instruction and an insertion / deletion editing instruction in row units.
That is, the definition information input means 1.6 performs processing of inputting text in the conditional expression description area, the judgment instruction area, the behavioral description area, and the behavioral instruction area, and the row insertion means 1.
7 and the row deleting means 1.8 perform editing processing of the conditional expression description area and the judgment instruction area, and the behavioral description area and the behavioral instruction area in units of rows. In response to the third end instruction, the definition information output unit 1.5 registers the edited definition information in the designated storage location, and the processing procedure generation unit 1.9 defines the decision table in text format. Convert to.

Next, a method of managing definition information by rows will be described with reference to FIGS. 2 and 3. FIG. 2 shows an example of definition information created by the device of the present invention. When this definition information is managed in units of rows, it becomes as shown in FIG. For example, in the first row 3.1, the condition description area 3.1.
The information of the 1 determination instruction area 3.1.2 is stored. It also has a management method that has connections between rows 3.1 and 3.2.

Next, an example in which a row is inserted by the row insertion means 1.7 will be described with reference to FIGS. 3 and 4.
If you insert a new row between rows 3.1 and 3.2, the result will be as in Figure 4. FIG. 4 shows a state in which row 4.2 is inserted, and at the same time, conditional expression description area 4.2.1 and determination instruction area 4.2.2 are inserted. When the row deleting means 1.8 is operated, conversely, row 4.2 in FIG. 4 is deleted, and at the same time, the conditional expression description area 4.2.1 and the judgment instruction area 4.2.2 are deleted. Three
Return to the state of.

Finally, an example of the processing procedure generation means 1.9 will be described with reference to FIG. FIG. 5 shows an example of a method of generating a processing procedure from the definition information of the decision table of FIG. The flowchart of FIG. 5 shows the flow of the generated processing, and FIG. 6 shows an example when the processing language is COBOL.

[0010]

According to the present invention, it is possible to easily associate the determination instruction area and the operation instruction area with each other by inputting them in a tabular form separately from other coding texts and the input area, and the language can be used at the time of input. It is possible to input without paying attention to the orthography of. Further, it is possible to edit the conditional expression description area and the determination instruction area, and the behavioral description area and the behavioral instruction area in units of rows.
