Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for editing data information in computer programming, and more particularly to the above-mentioned editing apparatus capable of visual display.

[0002]

2. Description of the Related Art Computer programming includes data design and procedural design. In data design, mapping, names, attributes, etc. of data used for procedural design are defined.

In this data design, it is customary to write in a text format as shown in the left column of Table 1 below.

[0004]

[Table 1]

[0005]

The data information expressed in the text format shown in the left column of Table 1 has a drawback that the programmer cannot intuitively grasp its size and structure. Further, it is necessary to grasp the agreement for each target machine (target CPU or target OS) when creating it. For example, integer type data (in
The size of t) is 8 bits for some target machines, but 16 bits for other target machines.
Alternatively, the character machine data (char) can be placed in the adjacent empty area next to the bit field in the target machine for making the structure (struct), but the character machine data can be placed in the above-mentioned bit machine in other target machines. The arrangement is such that it cannot be placed in the empty area adjacent to the field and must be placed on the lower side. The programmer has to always proceed with the design work with such a detailed agreement in mind, and this is a work in which errors are likely to occur.

[0006] Further, when the designed data structure is changed so as to be compatible with the changed target machine along with the change of the target machine, it is necessary to understand the above-mentioned arrangement, and it is a mistake. It is a work that is likely to occur.

The present invention has been proposed in view of the above-mentioned conventional circumstances, and makes it easy to recognize the contents of the data information by visually recognizing it, and at the same time, the data information visually displayed. It is an object of the present invention to provide a method and apparatus for editing data information in computer programming that can reduce design errors by determining whether or not is compatible with a target machine.

[0008]

The present invention employs the following means in order to achieve the above object. That is, FIG.
In the data definition work of computer programming as shown in FIG. 5, a storage unit 10 that stores a data mapping rule corresponding to each target machine, a display unit 20 that displays data information in a combination of figures and areas,
It comprises an editing means 30 for editing the graphic obtained on the display means 20 so as to conform to the data mapping rule.

[0009]

[Operation] First, the basic data information at the start of work is
It is displayed on the display means 20 with a figure and an area corresponding to the number of bits of the data. For example, basic data is an integer type (int), and the integer type data is represented by a rectangle (here, referred to as an initial area) having a length (area) of the number of bits corresponding to the integer type data. After that, the editing means 30 is used for editing as follows. That is, a name is first given to the data corresponding to the initial area, and then the attribute is changed or the data length is changed (the number of bits, that is, the rectangle length) is changed from the initial state if necessary. . Editing means 3
In the case of 0, it is judged from the attribute of the data corresponding to the new rectangle formed in this way whether the length or position of the data is appropriate or not by referring to the mapping rule stored in the storage means 10. Also, when the data information is a structure, a plurality of rectangles corresponding to the data of a certain length that represents a certain attribute edited as described above are stacked, and an additional function for performing the work is added. Is equipped with.

In this way, the result edited by the editing means 30 is displayed on the display means 20, and then the storage management means 40.
Entered in. As a result, the programmer can visually recognize the data information, and the mapping rule prevents the user from inputting an incorrect input, so that the design error can be eliminated.

Further, when the target machine is changed (for example, a 32-bit CPU to a 16-bit CPU),
The graphic display is adapted to the changed target machine.

[0012]

FIG. 2 is a more detailed functional block diagram of the editing means of the present invention, FIG. 3 is a flow chart showing the basic procedure of the present invention, and FIGS. 4 and 5 are text displays. FIG. 6 is a flow chart in the case of editing data information corresponding to a 16-bit CPU using the present invention.

First, the initial area display means 31 is activated, and a 16-bit integer type data area (int) 1a is displayed as an initial area on the display screen of the display means 10 (FIG. 3, FIG.
Step F1, FIG. 4 (a)).

Next, the data name s is set in the area by the data name assigning means 32 (FIG. 3, step F2,
FIG. 4B). When this name assignment is completed, the changing means 33
Since any one of the adding means 36 is activated, the changing means 33 is instructed to change the integer type data into a structure on the screen. That is, "Change" in the displayed work menu
Then, "struct" representing the structure is designated by a mouse (pointing device) (step F4: In this case, "addition?" In step F3 is NO).

As a result, the integer type data area 1a displayed as described above is regarded as a sub area, that is, one area forming the structure, and its attribute (integer type is detected here, mapping rule is detected). (Steps F5 → F6) Here, even if the sub-region 1a is an integer type, it does not violate the mapping rule, so that the placement processing means 34 is activated next (step F).
Proceed to 7). In this case as well, there is no need to change the layout in particular, so the process returns to step F2 and the data name a is given to the sub-region 1a of the structure s (FIG. 4 (c)).

Next, when "add" is instructed in the work menu displayed on the screen, the adding means 36 is activated, and when the lower left corner of the sub area 1a is designated as the adding position by the mouse, the initial area displaying means 31 is displayed. Move to above sub-region 1a
Underneath, an integer type sub-region 1b is added as an initial region (FIG. 2, steps F3 → F31 → F1, FIG. 4).
(D)).

A data name b is given to the new area added in this way by the naming means 32, and then, in order to change the data attribute of the data b to a bit field (Unsigned), "change" is displayed on the screen. "→" Unsigned "is instructed to operate the changing means 33 (FIG. 3, step F2 → F).
3, FIG. 4 (e)). As a result, the size of the area 1b can be changed in bit units, so that the size of the area 1b is changed to 4 bits by using the mouse (FIG. 3, step F4).
→ F5, FIG. 5 (f)), it is determined whether or not this change complies with the mapping rule (FIG. 2, step F6).
Further, the placement processing means 35 operates to perform placement processing of the area whose size has been changed as described above (step F7).

Next, by again instructing "add" on the screen to activate the adding means 36, and by pointing the lower left side of the sub-region 1b with the mouse, the integer type sub-region 1c as the initial region is formed. It is displayed below the sub area 1b,
Let the name be c. Then, "change" is instructed to operate the changing means 33, and the integer type sub-region 1c is changed to a character type
Change instruction to r) (Fig. 5 (g) → (h)).

Since the character type is an 8-bit unit, the sub area 1c is changed to an 8-bit area.
Further, according to the mapping rule in this case, if there is a vacancy of 8 bits or more in the horizontal area adjacent to the bit field, it is edited so that 8-bit character type data is automatically inserted in that area. Therefore, in this case, the arrangement processing means 3
5 operates to arrange the character type 8-bit sub-region 1c adjacent to the bit field 1b.

Next, since the size of the character type data can be changed in units of 8 bits, "change" is instructed to operate the changing means 33 to enlarge the sub area 1c.
16 characters in total when converted to 2 units of character type data
Since it is a bit length, it is 12 adjacent to the sub-region 1b.
Does not fit in the bit area. At this time, the placement processing means 35 expands the sub-region c according to the mapping rule.
Automatically moves to the lower side of the sub-region b (see FIG. 5).
(I)). When the above procedure is completed, the storage management means 40 manages the information data created by instructing the end (FIG. 3, step F7).

Even if an erroneous input is made in the above-mentioned editing process, for example, if the size of the area is changed without instructing the change to Unsigned, or if 16-bit CPU is used for data design, 16-bit Even if the exceeded data is arranged, the program is not operated at all or an alarm is displayed because the restriction is imposed by the mapping rule (FIG. 3, step F61). Therefore, there are no erroneous inputs.

FIG. 6 shows an updating means 50 for changing data information designed for a 32-bit CPU for a 16-bit CPU.
It is an operation | movement flowchart of (refer FIG. 1). That is, as shown in FIG. 6, the attribute of the conversion target data is first determined (FIG. 6, step 101). When the determination target data is not a structure, the data is converted according to the change rule from the 32-bit CPU to the 16-bit CPU (FIG. 6, step F102 → F103), and then the conversion result is displayed (FIG. 6, step F104). ). If it is a structure, the attributes are sequentially determined from the first data, and the attribute is changed according to the change rule (FIG. 6, step F105 →
F106), all the data changed when all the data have been changed are displayed (FIG. 6, step F104).

From the above 32-bit CPU to 16-bit CP
The rule for changing to U is, for example, that integer type data in a 32-bit CPU becomes a 16-bit long integer type, and 32
The short integer type in bits becomes integer type data in 16 bits. Note that the character type data is in 8-bit units for both the 32-bit CPU and the 16-bit CPU, and the bit field is in 1-bit units for both the 32-bit CPU and the 16-bit CPU.

The above points will be further described with reference to an example shown in FIG. First, the conversion target data shown in FIG.
In the definition of bit CPU, Is. That is, this data is a structure, and the data corresponding to the first sub area a is an integer type (int). Therefore, this data area is converted into a data area for a 16-bit CPU and represented by a long integer type (long). Next, since the second data area b is a 4-bit bit field (Unsigned), this data has 16 bits.
When changed to bits, it is also represented as a 4-bit bit field (Unsigned).

Further, since the third data area c is a character type (char) of 2 units [1 unit is 8 bits], it is 16 bits as a whole. Therefore, a 32-bit CPU
In the data design for CPU, the second data area b (bit field) could be adjacent to it, but for a 16-bit CPU, since the empty field adjacent to the data area b is only 12 bits, the data area c Will be displayed below the data b.

As a result, the converted data is shown in FIG.
As shown in Becomes

[0027]

As described above, according to the present invention, since the data structure can be visually displayed, the programmer can easily recognize the data structure. In particular, when trying to use external data (data information designed by another person), its size and attributes can be surely grasped, and the design work becomes easy. Also, the input data information is compared with each mapping rule,
Since the correctness is determined, design mistakes are eliminated. Further, even when the target machine is changed, the data information can be automatically re-edited so as to match the target machine, so that design mistakes are eliminated.
