Abstract

PURPOSE:To surely and easily make data visible and readable without breaking a table format by displaying data in the display area outside the table when all data can not be displayed within the table. CONSTITUTION:When a key input 12 gives slip output instructions to display slip data previously inputted and formed in a variable length data file 13 and to confirm its contents, a CPU 11 outputs the table of a prescribed format and carries out displaying operation. Out of the slip data in file 13, the first word data of head searching data is read at first. The whole data is checked whether or not it can be displayed in corresponding columns of the table. When the number of digits of data is less than the possible maximum display number of digits of the corresponding table columns, the contents of the table 13 are read out one word at a time and displayed in the table columns. On the other hand, when the number of the data digits exceeds the maximum number of digits columns of the table columns, the data is stored and held in a data buffer 17 in order and the display key of the input part 12 is operated to read the data and to display it in the overflow display area outside the table.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display control device that displays data in a table column of a form or the like.

[Summary of the Invention] The present invention provides a display control device that outputs a table in a predetermined format on a display screen and displays corresponding data in each column constituting the table. If the data cannot be displayed in a column, a special mark is displayed in the column, and the data is also displayed in another display area on the same display screen.

[Prior Art] Conventionally, when an office computer or a personal computer receives a display command to check previously created form data, it displays a form in a predetermined format on a CRT screen, and also displays each form forming the form. The corresponding form data is assigned to each column and displayed and output in sequence.

Therefore, when displaying this type of data in a corresponding column, the number of digits of the data may exceed the maximum number of displayable digits of the corresponding column.

[Problem to be solved by the invention MJ Therefore, as mentioned above, if the number of digits of data to be displayed exceeds the maximum number of digits that can be displayed in the corresponding column, the data should be changed so that the data fits within the column. Possible methods are to display the data in a reduced size, or to expand the column vertically and display the data over several lines.

However, with the former method, the data may become difficult to read, and with the latter method, the pre-designed form format becomes vertically long and the form format itself collapses.In other words, the form format must be destroyed. Data cannot be displayed reliably.

For this reason, if data cannot be displayed in the corresponding table column, in addition to displaying the data in a separate area outside the table, it is also possible to display information on which column in the table the data in this separate area corresponds to. It is clear that if the data can be identified, the data can be read reliably and easily visually without destroying the one-table format.

An object of this invention is to display the data in a separate area outside the table in correspondence with the table column when the corresponding data cannot be displayed in the table column.

[Means to solve the problem] The means of this invention are as follows.

The determining means 1 (see the functional block diagram in FIG. 1; the same applies hereinafter) determines the column to which the number of digits of data to be displayed corresponds when the corresponding data is assigned to each column constituting a form and output. Determine whether it is within the maximum number of displayable digits.

The first display control means 2 causes the data to be displayed once to be output as is in the corresponding column when the determination means 1 determines that the data is within the range.

When the first display control means 2 determines that the display is out of range, the second display control means 3 uses a special mark (for example, "*
" symbols, figures, special characters, etc.) are output in the corresponding column, and all data to be displayed is output in a predetermined display area outside the table.

[Work] The operation of the means of this invention is as follows.

Now, when a form output command is given to confirm previously created form data, a form in a predetermined format designed in advance is displayed and output on a display screen such as a CRT.

Here, the determining means 1 determines whether the number of digits of the data to be displayed is within the maximum number of displayable digits of the corresponding column when outputting the corresponding data to each column constituting the table. .

Now, if the number of digits of the data to be displayed is 4 digits and 5 digits from the maximum number of displayable digits in the corresponding column, the first display M control means 2 corresponds to the data to be displayed. output as is in the field. In this way, when the determining means 1 determines that it is within the range, the first display controlling means 2
The table is displayed and output while allocating corresponding data to each column making up the table.

Therefore, if the number of digits of the data to be displayed is 7 digits, and the maximum number of digits that can be displayed in the corresponding column is 5 digits.

Since the determination means 1 determines that the data is outside the range, the second display control means 3 displays the special mark in the corresponding field and displays the data to be displayed outside the table in a predetermined display area. Output to .

Therefore, if the corresponding data cannot be displayed in a table column, the data can be displayed in a separate area outside the table in correspondence with the table column, without disrupting the pre-designed display format. Data can also be read easily.

[Example J Hereinafter, an example will be described with reference to FIGS. 2 to 7.

FIG. 2 is a block diagram showing the basic configuration of an office computer.

The CPU II controls various operations of this office computer according to pre-stored microprograms, and when form data is input from the key human power section 12, the input form data is transferred to a variable length data file 1.
Then, when the CPU II receives a form output command from the key human power section 12, it reads the form data from the variable-length data file 13 and provides it to the display control section 14, which is configured by the CRT display device. A display is output from the display unit 15 formed by the display. At this time, the CPU 11 outputs a table in a predetermined format on the CRT screen of the display unit 15, and allocates corresponding data to each of the columns constituting one table. Here, when outputting the corresponding data to each column that makes up the table, the CPU II determines whether the number of digits of the data to be displayed is within the maximum number of digits that can be displayed in the corresponding column. The CPU II writes the determination result to the flag memory 16 in correspondence with each column.Furthermore, if the number of digits of the data to be displayed exceeds the maximum displayable number of digits, the CPU II writes all the data to the data buffer 17.

FIG. 3 is a partial configuration diagram of the variable length data file 13. Note that in this embodiment, form data is treated as variable-length data with a record delimiter code r (J) added to each record, and a word delimiter code "," added to each word of l records. The long data file 13 sequentially stores variable length form data as shown in FIG.

FIG. 4 is a partial configuration diagram of the flag memory 16 and data buffer 17. This flag memory 16 has a flag area of 1 bit corresponding to each column constituting the table, and the maximum number of digits that can be displayed is predetermined for the column to which the number of digits of data to be displayed corresponds. If it is within the range, a flag 0'' is set in the flag area corresponding to the column, and if it is outside the range, a flag 1'' is set in the flag area corresponding to the column.

Further, the data buffer 17 sequentially stores data to be displayed in the table column corresponding to the area in which the flag 1'' is set among the flag areas constituting the flag memory 16.

Next, the operation of this embodiment will be explained.

Now, in order to display the form data input and created in advance in the variable length data file 13 and check its contents, when a form output command is given from the key human power section 12, CP [Jll
outputs a table (table frame, label name, etc.) in a predetermined format designed in advance, and starts executing a display operation according to the flowchart of FIG.

First, the first word data of the first record of the form data in the variable length data file 13 is read out (step AI), and the number of digits of this word data is compared with the maximum number of displayable digits of the corresponding table column. By doing so,
It is checked whether all of this word data can be displayed in the corresponding table column (step A2).

Here, if the number of digits of the word data is less than the maximum number of displayable digits of the corresponding table column, it is determined in step A2 that the word data can be displayed, and the process proceeds to step A7 to output the word data to the corresponding table column. Then, a flag 0'' is set in the area corresponding to the table column among the flag areas constituting the flag memory 16 (step A8).

Then, the process proceeds to step A6, and it is checked whether all the form data for one screen has been read. However, since the first word of the lth record has been read, the process returns to step AI, and the variable-length data file 13 is read out. Read the next word data from.

In this way, the contents of the variable length data file 13 are sequentially read word by word, and if the read word data can be displayed in the corresponding table column (Y in step A2).
ES), similarly to the above, the word data is displayed in the corresponding table column and flag 0'' is set in the corresponding area of the flag memory 16 (steps A7, A8).

Now, when word data regarding the price of the product indicated by the product code r020781J is read out from the variable length data file 13 as shown in FIG. 7, the maximum displayable digit of the table column to which the word data corresponds It is assumed that the number exceeds a number (for example, 5 digits). Then, in step A2, this is detected and the process proceeds to step A3, where the maximum number of overflow markers that can be displayed is displayed in the corresponding table column.
Output the display for the number of digits (5 digits). Then, in the next step A4, the flag l'' is transferred to the corresponding area of the flag memory 16.
Set. Next, all the word data is set in the data buffer 17 (step A5). If the word data read from the variable-length data file 13 cannot be displayed in the corresponding table column, the table is The overflow mark "tree" is displayed in the column to notify that fact, and the word data is not displayed in the table column.

All of them are stored and held in the data buffer 17.

The process then proceeds to the next step A6, returns to step A1, and repeats the above-described operation word by word until all data reading for one screen is completed.

When data reading for one screen is completed in this manner, the data that cannot be displayed in the table column is sequentially stored and held in the data buffer 17.

When a content display key (not shown) provided in the keypad unit 12 is operated in order to confirm the contents of the data buffer 17, the CPU II will display the flowchart shown in FIG. 6 every time the content display key is operated. Execute the action accordingly.

First, the CPU 11 sequentially searches for areas where the flag "l" is set from the top area of the flag memory 16 (step Bl).

When an area in which the flag 1'' is set is retrieved (YES in step B2), the cursor is displayed in the table column corresponding to that area (step B3) 0 For example, as shown in FIG. 7, the product code r020781 '' By inverting the table column for the price of the product as indicated by diagonal lines in the figure, a cursor is displayed at the position of the table column. Then, the corresponding word data is read from the data buffer 17 and displayed in the overflow display area at a predetermined position outside the table (step B4). OA indicates an overflow display area, and data to be displayed in the table column currently displayed with the cursor is displayed and output to the overflow display area OA. Note that FIG. 7 shows an example in which an overflow display area OA is provided on the lower side outside the front.

When the content display key is operated again, the operation according to the flowchart in Fig. 6 is executed, and as a result, the contents of the next table column where the overflow mark "tree" is displayed are displayed and output to the overflow display area OA. can be done.

In the above embodiment, the overflow display area OA is provided at the lower side outside the front, but the overflow display area OA can be placed at any position as long as it is outside the front.

Furthermore, in the above embodiment, data for one word is displayed in the overflow display area OA, but data for multiple words may be displayed simultaneously. In this case, each word data is The identification data may also be displayed to make it a part.

[Effect of the invention] This invention allows, when the corresponding data cannot be displayed in a table column, to display the data in a separate area outside the table in correspondence with the table column. It is possible to easily read data without destroying the table format. Even when designing a bifurcated table format, there is no need to consider the length of the data, so the format can be designed easily. can.
