An application program is provided to perform a predetermined operation, and development of this application program is necessary for each group. by the way,
For display control in a system with a man-machine interface, in order to improve the diversion of the program created as an application and reduce the difficulty of the program, the display data is separated as much as possible from the ROM (R
It is stored on the ead Only Memory), and the application controls the display by referring to the data.

[0004]

2. Description of the Related Art Therefore, an application program is configured to refer to data defined on a ROM, and a fixed data or
RO for all data regardless of variable data
References to M are made. Here, the fixed data is data that does not change due to the display trigger, and the variable data is data that changes due to the display trigger and is set by inputting a value at a desired time. , "Next page" characters and the like that are used fixedly are referred to as fixed data, and "94/08/20" characters and the like that can be changed are referred to as variable data.

[0005]

However, such a conventional configuration has the following problems. That is,
For variable data, it is necessary to control the display arbitrarily by the application, but for fixed data, because the application does not need to be aware of display changes, it refers to the ROM, so the application program cannot be created. It becomes complicated.

Further, since the content of the application includes the ROM reference part regarding the display control of the fixed data, it is necessary to use different applications depending on the hardware configuration, and it is difficult to divert the applications in the different hardware configurations. . Furthermore, when performing fixed data display control with variable data uniformly,
Since the entire screen is re-displayed, if a device having a low display speed such as an LCD display and a low response performance is used as the display means, the redundancy becomes high and the desired processing speed cannot be obtained.

The present invention has been made in view of the above problems, and manages variable items and fixed items by a general-purpose display control process to reduce the amount of work required for developing an application program. An object of the present invention is to provide a general-purpose screen display processing method in a screen display control device, which can improve the display speed by suppressing the redundancy at the time of displaying each element.

Seventeen means are provided.

Desired control is performed by each of these means performing the operation according to each of the flow charts shown in FIGS. 11 to 33, and each data structure of FIG. 1 is configured by the operation shown in FIG. Here, first, FIGS.
Regarding the control of each screen display shown in (b), FIGS.
To explain along the flow chart shown in FIG. 4, the menu screen display of FIG. 4 is step X1 as shown in FIG.
In, the display initialization processing is performed by the display initialization processing means 101.

The display initialization processing means 101 is shown in FIGS.
According to the flowchart shown in FIG. 4, operations such as securing each storage area are performed as described later. Next, in step X2, a screen clear operation is performed to erase the display of the entire screen. Then, in step X3, the display control processing by the display control processing means 102 is performed.

The display control processing means 102 is shown in FIGS.
Each item is displayed as described below according to the flow chart of. As a result, the screen display shown in FIG. 4 is established, and the input waiting state of the next step X4 is entered. After that, by selecting an icon corresponding to any of the items "ordering", "introduction", "reference", "send", "confirm", and "initial setting", in step X5,
The corresponding process is activated.

When the "order" icon is selected, the display control up to the display of FIG. 6 is performed according to the flowchart of FIG. First, in step Y1, the display initialization processing is performed by the display initialization processing means 101. The display initialization processing means 101 performs operations such as securing each storage area as described later according to the flowcharts shown in FIGS.

Next, in step Y2, a screen clear operation is performed to erase the display of the entire screen. Then, in step Y3, a determination is made as to "is there a page transition?", And if "present", step Y4 is executed through the "YES" route. In step Y4, the screen editing process is performed by the operation shown in FIG. 8, and each display is changed or erased as described later.

On the other hand, when the "1/2" page shown in FIG. 6 (a) is displayed, since it is the initial state where there is no page transition, the step Y5 is executed without executing the step Y4 through the "NO" route. Is executed. This allows step Y
Display control processing by the display control processing means 102 is performed for the initialized state in 1.

As a result, the display state of FIG. 6A is achieved, and the input waiting state in step Y6 is entered. In step Y6, when vegetables are selected as shown in FIG. 6A, the data processing operation of vegetables is started in step Y7, and the processing operation of the corresponding type is started by the selection of various items. It

By the way, regarding the display of FIG.
If there is a page transition when the icon corresponding to "next page" is selected, the "YES" route is taken in step Y3, and after the screen editing in step Y4 is executed,
Display control processing is performed by the display control processing means 102 in step Y5. As a result, the display of variable items is changed, the display page “1” becomes “2”, the data name “vegetables” becomes “drinks”, and the data name “meat” becomes “consumables”. , The data names “fish” and “fruits” are erased, and each delivery date is changed to the corresponding date [see FIG. 6 (b)].

At this time, the display state of the fixed items other than the variable items is maintained as it is. Now, the screen editing process in step Y4 will be described in detail. Each processing operation is performed according to the flowchart of FIG. First, in step Z1, the display character string change processing operation is performed by the display character string change processing means 104, and specifically, "1" of "1/2" is changed to "2" for the display page which is a variable item. A process of changing the display character string to be changed is performed.

Next, in step Z2, it is determined whether or not there is display data. If there is display data, the display character string change processing means 104 changes the display character string in steps Z3 and Z4. Be done. That is, in step Z3, for the data name that is a variable item, specifically, the display character string changing process for changing "vegetables" to "drinks" is performed.

In step Z4, the date name which is a variable item is specifically "94/08".
The display character string is changed to change "/ 20" to "94/08/24". Then, in step Z7, the number of display items is compared, and through the “NO” route until the operations of steps Z2 to Z4 are performed for all item display positions (4 places in the example of FIG. 6) on the same page. Is repeated.

By the way, when it is determined in step Z2 that there is no display data [in the example of FIG. 6 (b), the third item position and the fourth item position on the next page],
Steps Z5 and Z6 are executed, and the display character string erase setting processing means 106 operates to erase the display character string. That is, in step Z5,
The display character string relating to the data name is deleted, and
In the example of (b), "fish" on the previous page at the third item position is deleted.

In step Z6, the display character string relating to the date is erased, and in the example of FIG. 6B, "94/08/23" on the previous page at the third item position is erased. As for the display of the fourth item position, since the number of display items has not been reached, “N” in step Z7.
Through the "O" route and the "NO" route in step Z2, the character string erasing operation similar to that of the third item position described above is performed.

After such an operation, the icon inversion operation in steps Z8 and Z9 is performed. That is, in step Z8, the display icon inversion setting processing by the display icon inversion setting processing unit 111 is performed according to the flowchart of FIG. 27, and the inversion operation for the icon to be inverted in this display is performed.

In the example of FIG. 6A, the icon inversion operation for the item "vegetables" on page 1/2 is performed.
Further, in step Z9, the display icon non-inversion setting processing by the display icon non-inversion setting processing unit 112 is performed according to the flowchart of FIG. 28, and the inversion elimination is performed on the icon for which the inversion should be eliminated for the current display.

In the example of FIGS. 6 (a) and 6 (b), when shifting to page 2/2, the operation of shifting the reverse icon for the item "vegetables" on page 1/2 to the non-reversing state Is performed. By the way, the operation of each processing means equipped to perform the above operation is performed as follows.

First, the display initialization processing means 101 is shown in FIG.
The operation according to the flowcharts shown in FIGS. That is, in step A1 of FIG. 11, the RAM area 52
An area 58 for changing the screen display data for storing the screen display data 54 of the ROM 51 to be transferred is secured in a required portion of the area (see FIG. 3).

Then, in step A2, the ROM 5
The screen display data 54 stored in No. 1 and linked to the screen data index table 53 is copied to the screen display data changing area 58, and operations such as changing the screen display data 54 in the RAM area 52 become possible. Next, in step A3, the number of variable display character strings is calculated by referring to the display data address in the screen display data changing area 58.

Next, in step A4, step A
From the calculation result of 3, it is determined whether or not there is a variable character string, and if there is, a "NO" route is taken to perform the processing for the variable character string in steps A5 to A9, and if not, "YES". The steps A10 and A11 are executed without executing steps A5 to A9 through the route.

First, in step A5, a character string display data changing area 59 for storing the transferred variable character string display data 55 of the ROM 51 is secured in a required portion of the RAM area 52. Then, in step A6, the variable total character string length is calculated by referring to the character data address in the character string display data changing area 59.

Then, in step A7, a character string data changing area 60 for storing the transferred variable character string data 56 of the ROM 51 is secured in a required portion of the RAM area 52. Further, in response to the above operation, in step A8, a character string data link establishing process is performed as described later according to the flowchart shown in FIG.

Then, in step A9, the presence / absence of replacement of the character string display data is set. Then,
In step A10, securing the display digit number storage area
The operation is performed according to the flowchart of FIG. 13 described later. Further, in step A11, the icon inversion state storage area is secured by the operation according to the flowchart of FIG. 14 described later, and the display initialization process is completed.

By the way, the above-mentioned character string data link establishment processing is performed according to the flow chart shown in FIG. 12. First, in step B1, it is judged whether the change item number has been set. Steps B2 to B5 are executed through the “YES” route. First,
In step B2, the variable data in the character string display data 55 is copied from the ROM 51 to the character string display data changing area 59 of the RAM area 52.

Then, in step B3, the ROM 5
The variable data of the character string data 56 in 1 is RA
It is copied to the character string data changing area 60 of the M area 52. Then, in step B4, the screen display data in the screen display data changing area 58 and the character string display data in the character string display data changing area 59 are set to be linked.

That is, the screen display data changing area 58
(Change area a) is searched, and the character string display data 55 in which the change item number is set is changed to another change area b on the RAM 52.
Copying is performed in (character string display data changing area 59) to establish a link between the changing area a and the changing area b. Further, in step B5, the character string display data in the character string display data changing area 59 and the character string data in the character string data changing area 60 are set to be linked.

That is, the change area c (character string data change area 60) for storing the display character string is acquired (step A7), and the link between the change area b and the change area c is established. Then, in step B6, it is determined whether or not the processing for each display data has been completed. If not, the processing in steps B1 to B5 is repeated.

On the other hand, the above-mentioned display digit number storage area securing process is performed according to the flow chart shown in FIG.
First, in step C1, the number of changed character strings is acquired, and in step C2, the determination of "Are there any changed character strings?" Is performed with reference to the acquired result. If there is a changed character string, go to step C through the "YES" route.
3 is executed to secure the display digit number storage area.

Next, at step C4, it is judged "whether or not it is a variable character string", and if it is a variable character string, the change item number is set. Then, step C6
In, it is determined whether or not the change item number has been set for all of the display modes, and steps C4 and C5 are repeated until each display mode ends.

By the completion of the setting of such a change item number,
The process for securing the display digit number storage area is completed. The above-described icon inversion state storage area securing process is performed according to the flowchart shown in FIG. 14. First, in step D1, the number of changed icons is acquired, and then step D
In 2, the determination of "Is there a change icon?" Is performed with reference to the acquisition result.

If there is a change icon, "YES"
Step D3 is executed through the route to secure the icon inversion state storage area. Next, in step D4, it is judged whether or not the icon is a variable icon, and in the case of a variable character string, the change item number is set.
Then, in step D6, it is determined whether or not the change item number has been set for all of the display modes, and steps D4 and D5 are repeated until each display mode ends.

By the completion of the setting of the change item number,
The process for securing the icon inversion state storage area is completed. By the way, the display control processing by the above-mentioned display control processing means 102 is performed by each operation according to the flowcharts of FIGS. 15 to 18. First, in step E1 in FIG. 15, the display item number is initialized, and step E2. At, it is determined whether each display mode is turned on.

When each display mode is not turned on,
In step E3, a display execution process is performed, and an operation according to the flowchart of FIG. 16 is performed as described later to perform each display. When the display execution process ends, the display item number is updated in step E4, and then the execution process for the next display mode is repeated.

By the way, the above-mentioned display execution processing is performed according to the flowchart of FIG.
The presence or absence of the display is confirmed in, and when there is the display, each operation from step F2 and step F3 to step F6 is performed. That is, along the branch for each display mode in step F2, if the display mode is a character string display, the character string display control of step F3 is performed, if it is an icon display, the icon display control of step F4 is performed, and if it is an underline display, If the underline display operation in step F5 is a straight line display, the straight line display operation in step F6 is performed.

Then, in step F7, the operation of resetting the presence / absence of display to "absence" is performed, and the display execution process ends. Here, in the above-mentioned character string display control, the operation according to the flowchart of FIG. 17 is performed, but first, in step G1, it is confirmed whether or not “display is present”.

When there is a display, step G2 is executed through the "YES" route to display the character string. That is, as shown in FIGS. 9 (a) and 9 (b),
If the previous display character string is "ABC", "XYZ
When "W" is displayed this time, since the number of characters displayed this time is larger than the previous time, "XYZ" is overwritten and displayed on "ABC", and "W" is overwritten on the space after "C".

Then, step G4 is executed. In the case of "no display" which takes the "NO" route in step G1, the character string display in step G2 is not performed and the length of the character string is displayed in step G3. Is set to "0" and step G4 is executed. Therefore, since the display is not performed for the items for which the display status is "no display", it is possible to reduce the redundancy of the display processing when the change amount of the display content on the screen is small at the time of page transition. it can.

By the way, in step G4, the previous display character string length is obtained and referred to, and in step G5, the previous character string length and the current character string length are compared, and if the previous character string length is large, Step G6 is executed. At step G6, the coordinates of the unnecessary character string portion and the rectangle are cleared. This operation will be described with reference to specific examples shown in FIGS. 10A and 10B. In this case, regarding the previous display character string “ABCDE”, this time “XYZ” is used as the display character string.

"XYZ" displayed this time is overpainted on the character string displayed last time, but depending on this, "DE" displayed last time.
Will remain. The operation of erasing this unnecessary character string is performed by clearing the rectangle. The rectangle is cleared by the clearing operation in the drawing mode, and is not performed in the character-based space character display. That is,
In the character-based space character display, it is necessary to search, read, and draw the space character from the Kanji ROM, and the processing speed is low, whereas the graphic coordinates of the relevant area are calculated and the rectangle of the area is cleared. Since the processing speed to be performed is much higher, the means for clearing the rectangle is used.

As a result, the redundancy required for erasing unnecessary character strings is suppressed, the processing speed is improved, and the display speed is low.
A particularly great effect can be obtained in a CD display or the like. Then, in the above-mentioned icon display control, the operation according to the flowchart of FIG.
In 1, it is confirmed whether or not "display is present".

When there is a display, steps H2 to H6 are executed through the "YES" route to draw an icon. First, step H2 is executed to acquire the inverted state of the previous icon. Using this acquisition result, a comparison is made with the presence or absence of inversion this time. If "inversion state does not match", it means that the inversion state should be resolved, so step H5 is executed through the "YES" route. , The icon rectangle is cleared.

Thereafter, in step H6, the drawing of the icon is performed and the desired icon display state is reached.
By the way, if the inverted states of the icons match,
Since the operations of steps H5 and H6 are not performed by passing through the “NO” route from step H4, the processing speed can be significantly improved as compared with the case of clearing and redrawing all the icons. it can.

If the icon is not displayed, step H3 is executed through the "NO" route from step H1 to clear the icon rectangle. In this way, when the display control processing means 102 is activated, the screen display data 58 of the specified change area a is referred to, display is performed according to the set data, and then the change area of each item is displayed. Whether or not to display the screen display data 58 existing in a is set to no display. This is an operation for not displaying the items whose display status is not displayed later.

When each character string is displayed, the current display character string length is compared with the previous display character string. If the current character string is shorter, the coordinates of the area corresponding to the difference are calculated and the rectangle is cleared. Further, when each icon is displayed, the previous inverted state and the current inverted state are compared, and only when they are different, the icon is redrawn.

Explaining the display release processing means 103, the processing operation according to the flow chart shown in FIG. 19 is performed. First, in step I1, it is judged "replacement?".
Steps I2 and I3 are executed through the "ES" route. In step I2, the variable character string storage area 60 is released, and in step I3, the variable character string display data storage area 59 is released.

Then, step I4 is executed, and the screen display data changing area 58 is released. If there is no replacement in step I1, step H4 is executed through the “NO” route without executing steps I2 and I3, and the screen display data change area 58 is released.

That is, when the display release processing means 103 is activated, the RA secured by the display initialization processing means 101.
The change areas a, b, and c on M are released, and the display control on that screen ends. Next, the display character string change processing means 10
The operation of No. 4 will be described. The operation is performed according to the flow chart shown in FIG. 20. First, in step J1, the changed character string is searched for data, and in step J2, the designated character string is set. Then, in step J3, the presence / absence of the display presence / absence flag is set.

As a result, the presence of display data is set at the time of determining the presence or absence of display data in step Z2 in FIG. That is, when the display character string change processing means 104 is activated, the character string display data corresponding to the specified change item number is searched in the change area b, and the linked character string is copied to the change area c. Further, the operation of setting the display presence / absence flag of the corresponding screen display data 2 to the presence of display is performed.

The display character string display setting processing means 10
The operation of No. 5 will be described. The operation is performed according to the flowchart shown in FIG. 21. First, in step K1, the data of the changed character string is searched, and then in step K2, the presence / absence of the display presence / absence flag is set. As a result, when the display control processing means 102 determines whether or not to display, the display presence setting is performed.

That is, the display character string display setting processing means 1
