Abstract

PURPOSE:To edit a completed program by decoding inputted flowchart information, converting it into an instruction word string of a specific data processing unit and obtaining a relative location on a flow with an instruction symbol executed precedingly as to each instruction symbol on the flowchart so as to add the obtained relative location information to each corresponding instruction word. CONSTITUTION:A user uses a keyboard 13 to move a cursor properly on a screen of a CRT display device 12, lots of instruction symbols 2 are arranged to complete the flowchart of the contents of desired job. The arrangement 2 is stored to each unit section 30 on a pattern buffer memory and an instruction word 3 is extracted from the section 30, the instructions are arranged by a prescribed rule to generate a BASIC program. Then the buffer memory is referenced and the relative location of the flowchart with the instruction word executed precedingly is obtained from the arithmetic operation. Then relative location information is added to each instruction word 3 of the program and the flowchart is accurately completed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to improvements in flowchart programming devices.

(Summary of the Invention) According to the present invention, a program (instruction word sequence) for causing a specific data processing device to execute a desired task can be programmed using a flowchart, and a program that is originally created based on the completed program can be programmed. This allows the accurate reproduction of flowcharts.

(Prior art and its problems) Conventionally, when creating a BASIC program using this type of flowchart programming device, the user operates the keyboard to move the cursor to place a command symbol (desired Complete the flowchart by drawing a figure (shape in which the BASIC 21 monic is surrounded by a rectangle, diamond, etc.).

Then, by the action of known conversion software, the flowchart information created on the screen buffer is converted into a BASIC command string, and programming is completed.

On the other hand, this type of flowchart programming device is usually equipped with a function to reproduce the flowchart based on the completed program for convenience such as debugging. The algorithm used for reproduction is based on certain rules, such as branching instructions such that affirmative branches go straight down, negative branches go right sideways, etc., so if we use the flowchart shown in Figure 6, Despite programming, when a flowchart is reproduced based on the completed program, a flowchart with a completely different image is created, as shown in Figure 7, which confuses the program creator. Ta.

One way to solve this problem is to attach the corresponding absolute coordinates on the flowchart to each instruction word in the completed program, but this would increase the program capacity due to the number of digits in the coordinate information. However, there is a problem that it cannot be put to practical use.

(Object of the Invention) An object of the invention is to update the originally created flowchart to iE ffr without significantly increasing the program capacity.
An object of the present invention is to provide a flowchart programming device that can be reproduced.

(Structure and Effects of the Invention) In order to achieve the above object, the present invention includes a flowchart input means for inputting flowchart information corresponding to desired work content, and a specific data 91 processing device for decoding the inputted flowchart information. a command string conversion means for converting the command string into a command string; a relative position calculation means for calculating the (eye-to-eye position) on the flowchart for each command symbol on the flowchart with the command symbol to be executed n times before; and editing means for adding the relative position information obtained to each corresponding instruction word in the instruction word string to complete the program.

According to such a configuration, the information added to each instruction word of a completed program only needs to be about 1 by 1 inch at most, so the program capacity does not increase significantly.
Moreover, it becomes possible to faithfully reproduce the flowchart originally created according to the completed program.

(Description of Embodiments) FIG. 1 is an external perspective view showing an example of a flow chart type programming device according to the present invention.

As shown in the figure, this flowchart programming device 1 includes a printer 11. CRT display 12. Keyboard 13. Personal computer 14. , u, and a floppy disk driver 15.

The personal computer 14 executes the control programs shown in the flowcharts of FIGS. 2 and 3 to perform program creation and flowchart reproduction processing.

First, the operation of creating a BASIC program will be explained based on the flowchart with reference to FIG.

The user uses the keyboard 13 to move the cursor appropriately on the screen of the CRT display 12, and as shown in FIG. 4, arranges a large number of command symbols 2 to complete a flowchart corresponding to the desired work content. do.

Then, each command symbol 2 is stored in each unit section 3 on the screen panzer memory, and the flowchart information input process is completed (step 201).

Then, by the action of a known editor, R is extracted from each unit section on the flowchart into instructions, and a BAS IC program is created by arranging the instructions according to a predetermined rule. The BAS IC program in this state is still the same as the conventional one (step 202).

Next, by referring to the screen buffer memory again, the relative position of each instruction word on the flowchart with respect to the instruction word executed immediately before it is calculated. That is, in FIG. 4, for example, instruction word 11FA≦
O' is the instruction ffi'rA=B executed before it.
With respect to J, it is in the relative position of "No. 1" downward and "○" to the right. In this way, the distances downward and to the right are determined for each previously executed seal word, and these are stored as relative position information (step 203).

Finally, by adding relative position information to each instruction word in the BAS IC program created in step 202, the final ASIC program is completed as shown in FIG. 5 (step 204).
.

As is clear from the figure, relative position information 5 is added to each instruction word 3 of the completed program 4. Therefore, based on this relative position information 5, the originally created flowchart can be accurately reproduced.

Next, the operation of reproducing the flowchart originally created based on the completed program 4 will be explained with reference to the flowchart shown in FIG.

First, if a completed relative position information bone BASIC program 4 exists, it is loaded into the computer 14 via, for example, the floppy disk driver 15 (step 301).

Next, when the input processing (step 301) is completed, necessary command words are searched for by following the completed program 4 and arranged in a certain order (step 302).
).

Next, each retrieved command word is arranged on the screen buffer according to the relative position information 5 attached to the end thereof (step 303).

As mentioned above, this arrangement is based on the relative position information 5,
This is done by finding the distance R to the right and the distance R to move down.

Next, each instruction word is connected to each other on the screen buffer according to the progress of the program, thereby completing the reproduction of the originally created flowchart (step 304).

Since the flow chart created as described above is created based on the relative position information 5, even if there is an empty space 6 as shown in FIG. The flowchart is reproduced with the empty portion 6 left in the same way as the originally created flowchart.

In addition, if a flowchart is created by regulating the formal branch to the right and the negative branch to the downward direction as shown in Figure 6, the flowchart will be reproduced according to the rules, and the original flowchart will be created. It will not confuse anyone.

In addition, the relative position information 5 added to each instruction word 3 is just the relative distance to the previous instruction word 3 to be executed, so at most 1 byte of information is added, increasing the program capacity. There's nothing to do.

The BASIC program completed with this device is slightly different from existing BASIC programs, but if the ink printer is used so that the relative position information 5 is treated as a comment, there will be no particular problem in program execution.
