Description: TECHNICAL FIELD The present invention relates to a vertical or horizontal scrolling of the entire screen in a display system for displaying a character string having a length exceeding the display width of the screen in a table format. The present invention relates to an in-column scroll display method in which many columns and rows can be displayed on one screen by providing a scroll function in a column that handles a long character string.

[Conventional technology and problems]

FIG. 1 is a diagram showing an example of a definition screen, and FIGS. 2 and 3 are diagrams showing an example of screen display in a conventional table display format.

Generally, when a character string is displayed on a screen in a table format, it is necessary to first define a table, and the definition screen is used for that purpose. FIG. 1 shows an example of the definition screen. When displaying character strings in table format,
First, a definition screen as shown in FIG. 1 (a) is displayed.
If you enter a table name in this definition screen, if the table is already registered, it will be shown in Fig. 1 (b).
Although the already defined contents are displayed like this, when registering a new table, the column names COL1, COL2, COL
3, data length TYPE, data width WIDTH, etc. are defined.
In FIG. 1 (b), CHAR (10) has a character string length of 10 characters, and CHAR (100) has a character string length of 100 characters. Means a character. The data width WIDTH of 10, 20 means that the width of the column is such that 10 or 20 characters can be displayed per line. When it is displayed according to such contents defined on the definition screen, it becomes as shown in FIG. Second
As is clear from the display example shown in the figure, column COL1 has the same data length and data width, so it is displayed with only one line, but column COL2 and column COL3 have the same data length. Is 100 characters, but the data width is 20 characters, so 5 lines are used to wrap and display. Therefore, in the columns COL2 and COL3, not only is it difficult to see a series of data, but also a blank portion is generated like the column COL1 and the screen is wasted, and many items cannot be displayed on one screen. or,
If the displayed character string is so long that it cannot be displayed on one screen, even if there is only one such column, even one item cannot be displayed on one screen. Therefore, FIG. 3 shows an example in which the definition of WIDTH on the definition screen shown in FIG. 1B is ignored and one item is displayed in one line. In the case of this example, although many items can be displayed, the data of one column occupies the screen and the relationship with other columns cannot be known. Vertical scrolling is adopted in the table format display as shown in FIG. 2 and horizontal scrolling is adopted in the table format display as shown in FIG. 3, which solves the above-mentioned problems. Not a thing.

[Object of the Invention]
