Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display method of two-dimensional array data used for debugging program development.

[0002]

2. Description of the Related Art Conventionally, debugging in developing various programs is often performed at the source level. This source level program is written in a high-level programming language such as C language.

During debugging, the source level program is displayed on the CRT or the like, and its execution and modification are repeated. Further, during debugging, it becomes necessary to confirm how the data of each data name (variable name) in the program is changed, for example, by executing the program.

The selection and display of data is usually executed by inputting a variable name from the command line. If the selected data is two-dimensional array data of M (rows) × N (columns), it is displayed. A numerical string of M × N data read from the memory is displayed on a part or the whole of the screen.

[0005]

In the conventional data display method for two-dimensional array data, a data name must be entered from the command line, and M × N numbers of the selected data are listed. Since it is only displayed, there is a problem in that it is not easy to grasp the state of the data, and the management, solution, etc. cannot be performed efficiently. Further, if the display screen is switched during the data display and the program display is interrupted, the program and the data cannot be viewed at the same time, which is inconvenient and there is a problem that efficient program development cannot be performed.

According to the present invention, by selecting the data name in the program on the screen without inputting the data name from the command line, the two-dimensional array data of the selected program name can be easily displayed near the program. To aim.

[0007]

In order to achieve the above object, in the data display method of the present invention, the data name of the selected data name is selected by selecting the data name of the program on the screen described in the programming language. The dimensional array data is divided into row or column unit data, and each unit data is distributed to each card with a row or column number heading, and the heading of each card and the contents of the card at the front position can be seen. A card holder having a shape in which each card is stacked is displayed near the program, and the selected card is positioned at the frontmost position by selecting the heading of each card in the card holder.

[0008]

In the data display method of the present invention configured as described above, the data name is selected from the program on the screen, and the data of the two-dimensional array of the selected data name is the unit data of one row or one column. Each is distributed to each card.

Each card is labeled with a row or column number, and an overlapping card holder is displayed near the program so that the header of each card and the contents of the front card can be seen. Moreover, by selecting the heading of each card, the order of each card in the card holder is changed so that the selected card becomes the frontmost card.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment will be described with reference to FIGS. In FIG. 1, 1 is a display screen such as a CRT,
Reference numeral 2 denotes a program displayed in a window in the upper left half of the screen 1 so as to be vertically scrollable, and is written in C language. 3 is a data name (variable name) of the data of the 3 × 3 two-dimensional array included in the program 1.

Reference numeral 4 is a data selection window displayed on the upper right of the screen 1, and displays an icon 5 for each data name of the program 2. Reference numeral 6 denotes a guard holder displayed at the lower right of the screen 1, which displays the cards 7 of one row or one column of the selected two-dimensional array of data in a shape in which they are stacked in the front-rear direction. 8 is a convex heading for each card 7.
Each row or column is numbered from 0.
Then, the screen 1 is displayed by the display device shown in FIGS. 3 and 4 being executed by the computer device such as the icon and the workstation during the debugging process of the program.

Next, the data of a desired two-dimensional array in the program 2 is converted into 3 × 3 of "data [3] [3]" in FIG.
Assuming that the data has the data name 3 of, the procedure for selecting and displaying this data will be described. First, with a mouse in a certain debug state, the desired data name 3
After designating the range, the data name 3 is double-clicked as shown by the arrow cursor 9 in the figure, and the data name 3 is selected and notified to the computer device. Then, steps S1 and S2 in FIG. The display moves to the selection icon display in S3.

Then, based on the notification of the data name 3, the computer device reads out the window 4 called "Watch" from the memory and forms (opens) it. Further, the process proceeds to step S4 and the icon 5 of the symbol mark of the two-dimensional array data registered in the memory is read out.

Further, the process proceeds to step S5, and the read icon 5 is displayed on the window 4 with the notified data name 3 attached.

At this time, a plurality of icons 5 are displayed in the window 4 in the order of selection, with the latest icon 5 at the top. Further, in step S6, the gradation of the data which is not currently active is lowered to make the display color gray,
The active / non-active of each data is displayed in an easy-to-see manner.

When the process of displaying the selected icon is completed, the process moves to the determination of icon selection in step S7. At this time, the icon 5 of the currently active data name 3 in the window 4 is designated by the arrow cursor 9 by the mouse,
When selected by double-clicking, this step S7
In the affirmative (YES), the process proceeds to step S8.
It is determined whether or not the icon 5 selected in step S8 is currently selected, and if not selected, the process proceeds to negative (NO) and the display moves to the card holder display in step S9.

In this card holder display, first, in step S10, the current respective values (numerical values) of the data of the selected data name 3 are read from the memory or the register. Next, in step S11, each read numerical value is divided into unit data, for example, one row, and the divided numerical values are distributed and assigned to each card 7.

Assuming that each row is the 0th, 1st and 2nd rows, first, as shown in FIG. 1, the card 7 in the 0th row is used as the frontmost card and each card 7 is stacked in the front-rear direction. The display data of the card holder 6 is formed, and the window of the card holder 6 with the 0th line as the frontmost card is simultaneously displayed in the vicinity of the program 2 based on this display data. At this time, since the headlines 8 of the respective cards 7 are provided so as not to overlap with each other, only the numbers 0, 1 and 2 of the headings 8 of the respective cards 7 and the three numerical values of the 0th line are displayed on the screen 1. The display is compact and easy to see.

In the card holder 6, when the headline 8 is selectively double-clicked by the mouse, the stacking order of the cards 7 is changed so that the card 7 selected by this click is located at the front. That is, when the heading 8 of the card 7 of number 1 is selected from the state of FIG. 1, the display of the card holder 6 is changed to the display in which the card 7 of number 1 is positioned before the card 7 of number 0 as shown in FIG. , The three numbers in the first line are displayed.

Then, the data of the two-dimensional array is simultaneously displayed in the vicinity of the program 2 in a card holder format, for example, one line at a time, and the heading 8 of each card 7 is displayed by the mouse.
By selecting, the front card can be changed freely and the contents of each line can be checked freely. By the way, when the determination in step S8 is made while the card holder 6 is being displayed, this step S8 is passed in the affirmative and the process proceeds to step S12 to close the window of the card holder 6 and erase it from the screen 1.

When the determination in step S7 becomes negative or the processing in steps S9 to S11 or S12 ends, the process proceeds to step S13 in FIG. By this step S13, it is determined whether or not the data content of the selected icon 5 has changed in the immediately preceding execution of debugging.

When the data content has changed, the process proceeds to step S14, and the content of the frontmost card 7 of the displayed card holder 6 is updated to the frontmost content (numerical value). Further, whether the determination in step S13 is negative or step S
When the process of 14 is completed, the process proceeds to step S15, debug is started, and the debug process is advanced.

Then, the process returns from step S15 to step S1 of FIG. 3 again, and the processing from step S1 is repeated. Therefore, desired data of the program 2 can be easily selected by selecting the data name 3 of the program 2 by operating the mouse instead of inputting the data name 3 from the command line.

Moreover, the data of the selected two-dimensional array is displayed in the vicinity of the program 2 by the window display of the card holder 6 so that it can be freely divided into, for example, lines, and the contents can be easily grasped and broken. it can. Further, in this embodiment, the data selection window 4 is displayed, and the data of the selected active icon 5 is displayed on the card holder 6 by selecting the icon of this window 4, so that, for example, the data of the same data name is repeatedly selected. It is extremely convenient in such cases. In addition, each column of the two-dimensional array data is distributed to each card 7 of the card holder 6,
Of course, the selected data may be displayed in the column unit.

[0025]

Since the present invention is configured as described above, it has the following effects. The data of the two-dimensional array having the data name 3 selected from the program 2 on the screen 1 is distributed to each card 7 by unit data of one row or one column, and a heading 8 of the row or column number is attached to each card 7. ,
The card holder 6 is displayed in the vicinity of the program 2 so that the contents of each heading 8 and the frontmost card 7 can be seen. Moreover, by selecting the heading 8 of each card 7, the selected card becomes the frontmost card. As described above, since the display order of the cards 7 in the card holder 6 is changed, desired data can be selected by designating the data name in the program without inputting the data name from the command line as in the conventional case. The displayed data can be divided into rows or columns in the vicinity of the program and can be freely displayed for easy viewing.
Data can be grasped and broken up very easily, and highly efficient program development is realized.
