DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program editing apparatus for automatically setting an abandonment level of an instruction in a graphic representation in which a control structure of a program is represented by a graphic symbol. In order to improve the productivity of program development, it has been practiced to represent instructions with graphic symbols, clarify the control structure of the program, and prevent errors in the control structure of the program. In this case, for the instruction to give up control over multiple stages,
It is desired that the level to be abandoned is automatically adjusted and expressed.

[0002]

2. Description of the Related Art Conventionally, an instruction (for example, an escape instruction) for displaying on a display a graphic expression expressing the structure of a program by a graphic symbol and abandoning the control in the graphic expression in a plurality of stages in the display. The user specifies each level from which level to abandon using the mouse.

[0003] In addition, when the level to be abandoned changes due to the editing operation, the user has to reset the level each time.

[0004]

As described above, the user determines the abandonment level that is abandoned by an escape instruction, for example, in a graphical representation of the structure of a conventional program with a graphical symbol, and uses the mouse to escape the abandonment level. Since the previous level (level to be abandoned) was specified and set, the user had to judge the graphic expression, decide the level of abandonment, and input it with the mouse, and set the wrong level of abandonment due to misunderstanding. There is a problem that such a program is created. Also, if the abandonment level changes by changing a part of the graphical representation of the program once created, the user must reset the abandonment level of the escape instruction in accordance with the change, and the change is troublesome. There was a problem that sometimes it was forgotten or incorrectly set.

[0005] The present invention solves these problems,
When an instruction with the level to be abandoned is edited (created, changed, etc.), the structure related to the instruction currently being edited is found by tracing the structure of the graphical representation and abandoning to this level, and the abandonment level such as an escape instruction is automatically set. The purpose is to reduce the burden on the user and eliminate errors.

[0006]

Means for solving the problem will be described with reference to FIG. In FIG. 1, the editing process 3 is for determining whether or not the editing operation is a command to abandon control in a plurality of stages.

In the level adjusting process 4, when it is determined by the editing process 3 that the command is a command to give up control in a plurality of stages, the level is traversed from this command to a higher level, and the level until the control related to the command is reached is obtained. is there.

[0008] The internal table 71 is for setting the abandonment level and the text in association with the symbol on the graphic expression.

[0009]

According to the present invention, as shown in FIG. 1, in response to a user performing an editing operation on a graphic representation, when the editing process 3 determines that the control is to be abandoned in a plurality of steps, The abandonment level is determined up to the level of control related to the instruction, and is displayed on a schematic representation.

Further, when the editing process 3 determines that the control is to be abandoned in a plurality of stages in response to the user performing the editing operation on the graphic representation, the level adjustment process 4 performs The level up to the upper level until the control related to the instruction is reached is obtained and displayed on a schematic representation.

In response to the user performing an editing operation on the graphic representation, when the editing process 3 determines that the control is to be abandoned in a plurality of stages, the level adjustment process 4 starts from the abandoned command. When the level up to the control up to the control related to the instruction is obtained, the abandonment level of the corresponding symbol (for example, the escape instruction) in the internal table 71 is set and displayed. I have.

Therefore, when an instruction with a level to be abandoned is edited (created, changed, etc.), the structure (control) relating to the instruction currently being edited is found by tracing the structure of the graphical expression and abandoning to this level. , The abandonment level such as an escape instruction is automatically set, thereby reducing the burden on the user and eliminating errors.

[0013]

Next, the structure and operation of an embodiment of the present invention will be sequentially described in detail with reference to FIGS.

FIG. 1 is a block diagram showing one embodiment of the present invention.
In FIG. 1, a program editing device 1 is a device that displays a graphical representation of a program configuration on a display device 10 using graphic symbols, and creates and edits a program using a keyboard input device 8, a mouse 9, and the like. Here, the abandonment level of the escape instruction in the schematic representation is automatically set, and is composed of the edit control unit 2, the input / output processing 5, the edit buffer memory 6, and the like.

The editing control unit 2 edits a program on the graphic representation displayed on the display device 10, and includes an editing process 3, a level adjustment process 4, and the like.

The editing process 3 is to execute an editing process by taking in an instruction or control in response to a user inputting or changing a command or control on the graphic representation of the display device 10, Here, an instruction to abandon control in a plurality of stages (for example, an escape instruction) is detected (see FIG. 2).

In the level adjusting process 4, when it is determined by the editing process 3 that the command is a command to give up control in a plurality of stages, the level is traced from this command to a higher level, and the level until the control related to the command is reached is determined. is there.

The input / output processing 5 performs input / output with the storage device 7, fetches data from the keyboard input device 8 and the mouse 9, and displays graphical representations on the display device 10. Things.

The edit buffer memory 6 is a memory used when performing various edits. The internal memory 71 is stored here. The storage device 7 is a large-capacity external storage device for storing created programs and the like.

The internal table 71 includes the display device 1
It stores the data of the internal representation of the graphic representation displayed on 0 (see FIG. 5). The keyboard input device 8 is for inputting commands, controls, and the like into a graphic expression displayed on the display device 10.

The mouse 9 is used for designating position information when copying or moving on a graphic representation displayed on the display device 10. The display device 10 displays a graphic expression represented by a graphic symbol, and allows a user to edit the program while viewing the graphic expression.

Next, the operation of the configuration of FIG. 1 will be described in detail according to the order shown in the flowchart of FIG. In FIG. 2, S1 performs an editing operation. In this case, the user operates a start point (start line), an end point (end line), a destination, and execution on a schematic representation of the display device 10, for example, a schematic representation of FIG.

In step S2, it is determined whether the command is a command for relinquishing the control in a plurality of stages. This is to determine whether the command edited by the user in S1 is a command to give up control in a plurality of stages. In the case of YES, for example, since [escape] in the schematic representation of FIG. 4A is an escape instruction and an instruction to abandon control in a plurality of stages, the level adjustment from S21 to S23 is performed. On the other hand, in the case of NO, for example, [determination] in the schematic representation of FIG. 4A is control, so it is determined whether or not the editing range ends at S3. S2 is repeatedly performed for command and control.

As described above, in response to the user performing an editing operation on the graphic representation of the display device 10, the editing operation is a command, and the command is a command for relinquishing a plurality of levels of control ( For example, in the case of the escape instruction in FIG. 4A, the process proceeds to the next level adjustment process. On the other hand, there is no need to adjust the level otherwise, so the following control,
Repeat until done for instruction.

In S21 of FIG. 2, the control is traced because it is determined in S2 that the instruction is an instruction for relinquishing the control in a plurality of stages.
In step S22, it is determined whether the control is related to the command being edited. YE
In the case of S, the current control stage (level) is set in S23, and the process ends. On the other hand, in the case of NO, S21 and subsequent steps are repeated for the next control and the like.

The processing from S21 to S23 will be specifically described. (B) In FIG. 4B, (1) Since the escape instruction is an instruction for relinquishing a plurality of stages of control, one is traced from the escape instruction. Judgment] is taken out, but since this is a control but not a control relating to an escape instruction, NO in S22 is obtained.

(2) The [judgement] traced by one is taken out. This is a control but not a control relating to the escape instruction, so that the result in S22 is NO. (3) Take out one more [repeat]. Since this is control and control relating to the escape command, S22
Is YES, and the current control stage (here, level 1) is set as the abandonment level of the escape instruction in S23.
In response to this setting, an arrow (indicating escape) is displayed from the escape instruction of FIG. 4B toward level 1 as shown in the figure.

As described above, when it is determined that the instruction to be edited is an instruction to abandon control in a plurality of stages (YES in S2 of FIG. 2), this instruction (for example, the escape instruction of FIG. 4B) From this point on, the control relating to the instruction has been reached by sequentially tracing [judgment], [judgment], and [repetition] (YES in S22 of FIG. 2), and this level is set as the abandonment level of the instruction to escape. As a result, the arrow shown in FIG. 4B (three levels of arrows) is automatically displayed.

Next, an example of an input operation will be described with reference to FIG. FIG. 3A shows a state before an escape instruction is input.
This is a graphical representation of the program structure displayed on the display device 10 with graphic symbols. Where [repeat],
[Judgment] is control (control structure).

[Call] is an instruction. The vertical line indicates the level of control, and is given as 0, 1, 2, 3 from the left.

In this state, an escape command is input from the keyboard at the position indicated by the arrow. FIG. 3B shows a state after the escape instruction is input. This shows a state after an escape instruction is input from the keyboard at the position of in the state of FIG. 3A and a series of editing processes is completed. This will be described below.

(1) The user inputs an escape command at the position shown in FIG. 3A (S1 in FIG. 2). (2) Since the escape command input in (1) is a command for relinquishing the control in a plurality of stages (YES in S2 of FIG. 2), one [determination] traced from the position of the escape command is taken out. This [judgment] is a control, but not a control relating to the escape instruction, and therefore proceeds to the next step.

(3) Take out one more [call]. Since this [call] is an instruction, it is not the control relating to the escape instruction, so the process proceeds to the next step. (4) Take out one more [repeat]. Since this [repetition] is control and control relating to the escape instruction, the level 1 at this time is extracted. This allows
When two levels from the level 3 to level 1 of the escape instruction are abandoned, they are set in the internal table 71 (described later). In response to this setting, as shown in FIG. 3B on the schematic representation of the display device 10, two arrows from level 3 to level 1 are displayed so as to be abandoned.

As described above, when an instruction for relinquishing control such as an escape instruction for a plurality of stages is input, the internal table is searched so as to find control related to the instruction by sequentially following this instruction and abandon it to the level at that time. When the number is set to 71, it can be automatically displayed like an arrow on the schematic representation of the display device 10.

Next, an example of a moving operation will be described with reference to FIG. FIG. 4A shows a state before the escape instruction is moved.
This is a schematic representation of the program structure displayed on the display device 10 with graphic symbols. Here, as the movement operation, a start point (start line) and an end point (end line) are designated with a mouse or the like to specify a movement range. And
Instructs the determination to move to the position as the destination.

FIG. 4B shows the state after the escape instruction is moved. This will be described below. (1) The user issues an instruction to move the rectangular range in FIG. 4A to the position (S1 in FIG. 2).

(2) In response to the instruction of (1), the symbol is moved as shown in FIG. (3) Next, since an escape instruction has been found here as an instruction to give up control in a plurality of stages among the instructions moved in (2) (YES in S2 of FIG. 2), the position of the escape instruction is 1 Take out the [judgment] that has been traced. This [judgment] is a control, but not a control relating to the escape instruction, and therefore proceeds to the next step.

(4) The [judgment] traced by one is taken out. This [judgment] is a control, but not a control relating to the escape instruction, and therefore proceeds to the next step. (5) Take out one more [repeat]. Since this [repetition] is control and control relating to the escape instruction, the level 1 at this time is extracted. This allows
When three levels from the level 4 to level 1 of the escape instruction are abandoned, the level is set in the internal table 71. In response to this setting, on the schematic representation of the display device 10, as shown in FIG.
It is displayed to abandon three.

As described above, when an instruction to relinquish control such as an escape instruction in a plurality of stages is moved, the internal table is searched so as to find control related to the instruction by sequentially following this instruction and abandon it to the level at that time. When the number is set to 71, it can be automatically displayed like an arrow on the schematic representation of the display device 10.

FIG. 5 shows an example of an internal table according to the present invention.
This is the internal data of the system, which is the source of the graphical representation displayed on the display device 10 of FIGS. 3 and 4, and is the internal table 71 of FIG. Here, the display level is information on which level in FIG. 3B is to be displayed.

Symbols are symbols displayed at display level positions. The number of abandonment levels indicates the number of levels at which an instruction such as an escape instruction that abandons control in a plurality of stages abandons. Here, 2 represents that two levels are abandoned.

The text indicates the contents (text) of the symbol. Therefore, when the escape is input at the position of as shown in FIG. 3 (a) to FIG. 3 (b), as shown in FIG.
Since the escape instruction abandons two levels from level 3 to level 1, the abandonment level is set to 2 as shown in FIG. By setting the abandonment level to 2, two arrows, ie, an arrow from level 3 to level 1, are displayed on the schematic representation of the display device 10.

FIG. 6 shows another example of a schematic representation of the present invention.
This is for the CAPE language. here,
This is a command for relinquishing the following two controls in a plurality of stages: Re-entry is repeated in the middle so as to input the current item group again.

The next input is repeated halfway so that the current item group ends and the next item group is input. In summary, ・ Escape is C language (break), CAPE (Escape, end of processing) ・ Repeat is C language (continue), CAPE
(Re-input, next input, etc.). In these cases, since the instruction is to abandon the control in a plurality of stages, similarly, the level at which the control is automatically abandoned during the editing operation (input, move, copy, part development, memo development, etc.) is detected, and the detected level is detected. The abandonment level can be set in the internal table 71 and displayed on a schematic representation.

[0045]

As described above, according to the present invention,
When an instruction with a level to be abandoned is edited (created, changed, etc.), the structure (control) relating to the instruction currently being edited is found by tracing the structure of the graphical representation, and a configuration is adopted in which the level is abandoned up to this level. , Abandonment levels such as escape instructions can be automatically set and displayed as arrows on the graphical representation. By this, at the time of editing operation such as escape instruction (input, move, copy, parts development, memo development, etc.),
An arrow or the like indicating the abandonment level of the escape instruction etc. is definitely displayed, and the burden on the user can be reduced.
The possibility of creating an erroneous program due to a user's misunderstanding is eliminated, and the productivity of program development can be improved.
