The items displayed in the list are those that can always be selected, those that can be selected based on predetermined processing conditions, or the selection conditions between items (for example, if a certain item has already been specified, Items cannot be selected, etc.)
There are things that can be selected based on.

[0004]

However, in such a conventional information processing apparatus, the items to be displayed in the list are those that can be selected at all times when the items are displayed in the list. There is a problem as described below, because some of them can be selected based on the processing conditions of No. 1 and some of them can be selected based on the selection conditions between items.

That is, in the conventional information processing apparatus, since the array contents of the preset input items are all displayed as a selection target, it is possible to select the items which can be selected depending on the selection condition between the items. Since the items are displayed in a mixed manner, for example, if the user selects an item that is not the selection target from the list display due to the relationship with the specified item, the information processing due to the item selection error will cause an error. There was a problem such as becoming.

In order to avoid such a situation, it is necessary to delete an item that is not a selection target from the item list display according to a selection condition, or to create a special selection device dedicated to an item that is not a selection target. It was The object of the present invention is to
An object of the present invention is to provide an information processing apparatus that optimally sets and displays the contents of items to be displayed as a list according to selection conditions between items.

[0007]

EXAMPLES Examples will be described in detail below with reference to FIGS. 1 to 6 are diagrams showing an embodiment in which the present invention is applied to a computer system. First, the configuration will be described. FIG. 1 is a block diagram of a main part of a computer system 1. In this figure, the computer system 1 is composed of a CPU 2, a key input unit 3, a selection control unit 4, a work memory 5, an item list table 6, a display memory 7, a display control unit 8 and a CRT 9, and each unit is a bus 10. It is connected to the.

CPU (Central Processing Unit) 2
Controls various parts in the computer system 1 according to various control programs stored in the work memory 5 to execute various information processing, and causes the display control part 8 to display the processing process and the processing result on the CRT 9, and also the keys. Input section 3
When the selection item is selected by the selection control unit 4 and the selection item is determined by the selection control unit 4, the determined selection item is output to the display control unit 8 to display the item list on the CRT 9, and the process related to the selection item is executed. The display control section 8 displays the processing result on the CRT 9.

The key input section 3 is provided with cursor keys, numeral input keys, character input keys, function keys, etc.
The pressing signal of the pressed key is output to the selection control unit 4.
The selection control unit 4 executes the control processing of the selection items according to the selection control program described later, and sets the selection items designated by the key input from the key input unit 3 in the item list table 6 as to whether or not the selection items can be selected. Whether the selection is possible or not is determined by the flag, and when the selection is possible, the designated selection item is output to the CPU 2.

The work memory 5 forms a memory area for temporarily storing data being processed when the CPU 2 executes various information processing according to various control programs. As shown in FIG. 2, the item list table 6 is an array having data pointers (addresses) for each item for the number of items N, and the item data stored in each item (items 1 to N) is the same. As shown in the figure, it is composed of "selectability flag", "designation flag", "display content", and "selection condition".

The "selectability flag" is a flag which is set on the basis of the selection condition and indicates whether or not selection is possible.
“0: selectable” and “1: not selectable”. The “designation flag” is a flag indicating whether or not this item has been designated, and is “0: non-designated” or “1: designated”. “Display content” is the name of an item displayed on the CRT 9.

The "selection condition" is a list of other items indicating whether or not the item is to be selected, and the condition setting includes other item names and conditional operators "|" (or), "&"
Describe using (and). When this selection condition is satisfied, the item is not selected and is not displayed on the CRT 9. The item set within this selection condition becomes true when the designation flag is "1".

The selectability flag is set in the work memory 5 immediately based on the item selection condition and the designation flag when the processing of the computer system 1 is executed. Therefore, in the computer system 1 of the present embodiment, when the selection item list is displayed, this item list table 6
In the above, it suffices to pay attention only to the items for which the selectability flag is set to selectable (“0”). However,
The selectable / non-selectable flag is reset by selecting or canceling an item when a plurality of items are selected.

FIG. 3 is a diagram showing a specific example of the data structure stored in the item list table 6. In this example, all selectable / non-selectable flags are selectable (“0”) and all designated flags are undesignated (“0”). It is "0"), which indicates the initial state in which no item is specified. In this example, the selection condition set in the display content “item 1” is “item 21 | item 22”, and item 1 is
This indicates that if item 21 or item 22 is specified, selection is not possible (“1”). Similarly, the display contents "item 21" and "item 22" indicate that selection is not possible ("1") when item 1 is designated. The display content “item 3” is always selectable (“0”) because no selection condition is set.

The selection condition set in the display content "item 4" is "item 1 & item 3", and item 4
Indicates that selection cannot be made (“1”) when item 1 and item 3 are designated.

The display memory 7 forms a memory area for temporarily storing the item display data read from the item list table 6 by the display control unit 8. Display control unit 8
Controls to display on the CRT 9 the processing steps and processing results of various control processes executed by the CPU 2, and when the selection item data is input by the CPU 2, the item list display data corresponding to the selection item is displayed. The display is controlled to be displayed on the CRT 9 based on the selectable / non-selectable flag of each item stored in the list table 6.

Next, the operation will be described. First, the selection control process executed by the selection control unit 4 will be described based on the flowchart shown in FIG. When a key input operation is performed in the key input unit 3 and a selection item is designated,
The designated selection item is recognized (step S1), the setting state of the selection propriety flag of the selection item is discriminated by referring to the item list table 6 (step S2), and selection is not possible (“1”). If so, a predetermined error process is performed and the process returns to step S1. If the selection is possible (“0”), the selected item data is transferred to the CPU 2 (step S3), and this process is executed. finish.

Next, the display control processing executed by the display controller 8 will be described with reference to the flowchart shown in FIG. First, when a selection item is input from the CPU 2, first, based on the selection condition and the designation flag set for each item stored in the item list table 6, the work memory 5 sets the selectability flag of each item. The above process is performed (step S11). Next, “0” is set to the display item number I indicating the number of items to be displayed (I ← 0), and the top display position is set to the display position Y indicating the display position of the item list (Y ← top display position). ) Is performed (step S12).

Next, it is judged whether or not the number of items is larger than the number of display items I (step S13). If the number of items is larger than the number I of display items, this process is immediately terminated and the number of items is displayed. If it is not larger than I, the set state of the selectability flag is determined (step S14). If the selectability flag is set to selectable (“0”),
The display content of the item is displayed on the CRT 9 based on the display position of the head set in step S12, and the display position Y is incremented by one item (Y ← Y + 1) (step S15).
After the display position Y is changed, or when the selectability flag is set to "not selectable"("1") in step S14, the display item number I is incremented by one item (I ←
I + 1) (step S16) and the process returns to step S13.

As described above, by the display control processing in the display control unit 8, for example, the item list table 6 is displayed as shown in FIG.
When the item data is stored as shown in (a), the items 21, 22 and 4 for which the selectability flag is set to not selectable (“1”) are not extracted and selectable (“ Only the items 1 and 3 set to 0 ") are extracted, and the item list is CR as shown in FIG.
Displayed at T9.

Therefore, in the computer system 1 of the present embodiment, unlike the prior art, the selectability flag is set for each selection item based on the selection condition, and when the selection item is designated, the selectability flag is selectable ("0. Since only the items set to ") are extracted and the selection item list is displayed, the optimum selection item list can be displayed according to the change in the information processing state. Since the set state is changed according to the change of the designated item, it is possible to flexibly deal with the change of the target of the selected item or the selection condition and display the list of optimum selected items.

[0026]

According to the invention described in claim 1, only the selectable items can be extracted to display the selection item list, and the optimum selection item list can be displayed according to the change of the information processing state. It can be carried out.

According to the second aspect of the present invention, the selectable / non-selectable state can be changed according to the change of the designated item, and the optimum selection can be made flexibly even if the target of the selected item or the selection condition changes. A list of items can be displayed.
