Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a unit processing method using macro instruction control in a data flow language processing system. The present invention relates to a unit processing method that can expand the processing range of a unit that can be controlled by one macro instruction.

[Technology background]

A program in a data flow language, HYPERCOBOL, for example, as shown in Figure 1a, consists of a unit that is the execution unit of processing, an input data area SA1, ... and an output data area for the unit.
It consists of SA2,...

The unit describes the contents of an arbitrary office processing unit that is processed frequently.

A unit description consists of three elements: a unit statement, an unconditional processing description, and a collection of WHEN descriptions. FIG. 1b shows one example.

Such a unit description is converted into a macro instruction, but in the conventional macro instruction technique, each ``case'' of the WHEN description, that is, the condition processing description, is separately converted as shown in Figure 2. It is necessary to map the macro instructions. Since a definition body is created for each type of macro instruction, the definition of one unit description is divided into multiple macro instruction definitions, making it difficult to understand how the entire unit description is defined. The drawback was that in order to know, it was necessary to refer to all the definitions of each of these macro instructions.

[Object and structure of the invention]

An object of the present invention is to create a macro having a definition structure that allows a unit that includes processing units of various contents, as in the case of the unit description described above, to be handled with a single macro instruction without increasing the number of types of macro instructions. To provide an instruction system, the definition body of macro instructions corresponding to one unit description is multilayered into a main definition body and sub-definition descriptions called from the main definition body, and the definition body of macro instructions corresponding to one unit description is layered into a main definition body and sub-definition descriptions called from the main definition body. By writing a specific definition and describing its specific or detailed purpose definition in the sub-definition description, the definition and calling relationship of the macro instruction is made into a multi-layered structure.
It is possible to express the contents of one unit description with the definition of one macro instruction.

The configuration of the present invention is that, in a data flow language processing system, a unit constituted by a unit statement of a data flow language program, an unconditional processing description, and a collection of WHEN descriptions is associated with a single macro instruction, and the macro instruction The definition body has a multi-layered structure consisting of a main definition body that describes an overall or common definition and a sub-definition description that describes specific or sub-purpose definitions, and a calling relationship is established between each layer of the multi-layered structure. By doing this, when referring to a definition field from the above macro instruction, the main definition field is first referenced, and if a call to a subdefinition description is set during the definition, that definition in the main definition field is used as the subdefinition description of the call. It is characterized by replacing it with a definition description and performing processing by referring to the definition body from a macro instruction.

[Embodiments of the invention]

Hereinafter, details of the present invention will be explained based on examples.

FIG. 3 shows an embodiment of a unit description definition body based on the present invention, with some parts omitted. In the figure, 1 indicates a macro instruction [EDITX], 2 indicates a main definition field, and 3 indicates a sub-definition description.

The process of this example is to create cumulative data in the output data area SA2 based on the amount data in the input data area SA1.

In main definition field 2, data A is represented by a two-digit number, and the initial value is zero; 1 is added to data A for one input record; and if data A = "1", that is, one subject name. Execute “FIRST” for the record, execute “SECOND” for data A=2, that is, for records with two subjects, and execute common processing (*) for A=3 and later, that is, other record codes. Things to do, etc. are defined, and in sub-definition description 3, the necessary details of, for example, are defined.

In this way, one unit is represented by one macro instruction, one main definition field and one sub-definition description are made to correspond to one macro instruction, and sub-definition description 3 is automatically generated from main definition field 2. By having it called, the definition for each unit can be referenced easily.

In the main definition body 2, for example, standard specifications provided by a manufacturer can be defined, and in the sub-definition description 3, user-specific extensions, exception handling, etc. can be arbitrarily defined.

FIG. 4 is a schematic diagram of definition program editing processing based on the embodiment of the present invention. In the figure, 4 is a macro instruction, 5
is an input section, 6 is a definition program extraction section, 7 is a main definition program file, 8 is a sub-definition description file, 9 is a main definition program analysis section, 10 is a sub-definition description analysis section, 11 is a source generation section, 12 is an output Section 13 indicates a source file.

The macro instruction 4 is sent from the input section 5 to the definition program retrieval section 6, where the name is used to search the main definition program file 7 and the sub-definition description file 8. A corresponding main definition field and sub-definition description are extracted from each file and supplied to the main definition field analysis section 9 and sub-definition description analysis section 10, respectively. These analysis units 9 and 10 analyze the main and sub definition bodies and supply them to the source generation unit 18. The source generation unit 18 replaces the definition of the corresponding main definition field with the definition described in the sub-definition description, performs predetermined editing processing, and outputs the result as shown by the arrow in FIG. The data is output from the unit 12 to the source file 13.

〔Effect of the invention〕

As described above, according to the present invention, by layering macro instruction definitions and calling relationships, a single macro instruction can be defined in association with various processing contents of a unit, and each unit can The definition of can be easily referenced.
