DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an HCP chart generation apparatus, an HCP chart generation method, and a recording medium on which an HCP chart generation program is recorded.
DL (Structured Transaction Definition Language)

2. Description of the Related Art Conventionally, as a high-level transaction processing (TP) language for creating a distributed transaction processing application, STDL (Structured Transac
tion Definition Language) is known. STDL
In the standard C language, COBOL (COMmon Busin
ess Oriented Language) or SQL (Structured Q)
Transaction control and exception handling that are not built into high-level languages such as uery Language are built into the language syntax.

Also, since the STDL does not have a function for performing complicated processing, all operations on databases and files, and access to displays, I / O devices, and the like, if these are required, each high-level language is used. These procedures are realized by calling the procedure. By adopting such a configuration, each high-level language does not need to add functions such as transaction control. Further, since transaction processing can be described without using an API depending on a specific transaction processing monitor, there is an advantage that portability of a transaction processing application can be improved.

A table for converting the P chart symbol into text data is stored in the external storage device 5. Hereinafter, a part thereof will be described with reference to FIG. The processing start symbol SB1 indicating the start of the processing is represented by ruled line text data “┬”, text data “デ ー タ”, and ruled line text data “┴”, as shown in FIG. Further, the symbol SB2 mainly describing the process description is represented by text data “○” as shown in FIG. The symbol SB3 describing the conditional branch is
As shown in FIG. 3C, it is represented by text data "@".

A symbol SB4 describing a subroutine call and a function call is represented by text data "「 "as shown in FIG. Further, the symbol SB5 for describing the loop is represented by text data “＠” as shown in FIG. Further, the symbol SB6 for indicating the end of the processing is shown in FIG.

The details of the symbol SB6 will be described later. Also, for lines (links) connecting the symbols, ruled line text data “─”,
It is represented by “|”, “┐”, “┬”, “├”, etc.

[4] Operation of Embodiment Next, the operation of the chart generating apparatus of the embodiment will be described with reference to the processing flowchart of FIG. First, MP
U2 indicates that the file to be converted input via the removable recording device 6 or the communication interface unit 7 is S
Whether or not the file is a file described in TDL is determined by the language identification function 21 whether or not the file extension, that is, whether or not the file extension = stdl. If the file to be converted is not a file described in STDL, the error output function 22 performs error processing notifying the fact. Input target file is STDL
If the file is described in step (1), the file is opened and the source program list is read into a temporary area on the memory (step S1).

Next, one line of the source program list once read into the external storage device 5 is read into the RAM 4 (step S2). In this case, it is assumed that the source program list also includes comment data. Next, it is determined whether or not the source program list has been completed (step S3). If the reading of the source program list has been completed in the determination of step S3, the process is terminated. If it is determined in step S3 that the reading of the source program list has not been completed, the symbol for the HCP chart corresponding to the source program list for one line is specified by referring to the table in the external storage device 5, and , The identified HC
The data is converted into text data corresponding to the P chart symbol, and comment data included in the source program list is extracted (step S4). In this case, the conversion of the source program list into the HCP chart can use various known methods as in the case of generating a flowchart from the program list.

Next, the MPU 2 outputs the obtained text data, source program list, and comment data to the display 10 (and, if necessary, the printer 9) in a predetermined output format (step S5). Here, the output format will be described with reference to FIGS. FIG. 5 is a diagram showing an output example, and FIG. 6 is an enlarged view of a portion A in FIG. As shown in FIG. 5, the output HCP chart is expressed using text data, a corresponding source program list is displayed on the right side of the HCP chart, and a corresponding comment data is further displayed on the right side. Is displayed.

More specifically, as shown by the arrow LN1 in FIG. 6, on the left side of the output HCP chart, it is indicated that the constraint condition of the parameter (argument) when calling the function is described. The text data “@” is displayed, and on the right side, a source list “CHECK_IN GSWP0401 NO described in STDL”
T TRANSACTIONAL PRIVATE, "
Is displayed, and the corresponding comment data “block check input” is displayed. Here, "CHECK_IN"
Is a display of a data name, “GSWP0401” is a display of a data type, and “GSWP0401 NOT T
The description of “RANSACTIONAL PRIVATE” indicates that the data name “CHECK_IN” defined by the data type of “GSWP0401” can be used in only one transaction. As described above, the HCP chart corresponding to the source list can be easily obtained, and the correspondence can be easily grasped. [5] Effects of the Embodiment As described above, according to the embodiment, the HCP in the text data format can be converted from the program described in the STDL.
A chart can be automatically generated and the created STDL
The program can be easily checked.

In this case, the comment data included in the STDL source list is also stored in the HCP chart and the STD.
Since the information is displayed in association with the L program, the checking operation can be performed more easily. Furthermore, since the obtained output result including the HCP chart is constituted by text data, it can be used in various text editors, word processors, etc., and can process and edit the HCP chart without using a special binary editor. Can be easily performed. Further, since the HCP chart can be automatically generated from the STDL source list, even when the STDL program is modified, the time for generating the HCP chart can be reduced, and the development efficiency can be improved.
