Reference numeral 7 is an FD (floppy disk) used as an external storage device for storing document information, page format information, management information, etc. of a document file.
It is a device. 8 is a keyboard 1, a CPU 2, a ROM 3,
I / O of RAM4, LCD5, printer 6, FD device 7
It is a bus line of O port.

FIG. 3 is an explanatory diagram showing the structure of the document data storage unit in the present invention. As shown in this figure, the page format information related to the page layout such as paper information, column information, header / footer information, etc., which is conventionally arranged in the header storage section (Header section), is newly added to the page format storage section. (Page Format section) is provided to store similar page format information for each page. Further, data indicating the number of the first character of each page from the beginning of the input character string is also stored in the page format storage section (Page Format section).

FIG. 4 is a block diagram illustrating the page formatting module of the present invention. As shown in this figure, a thick solid line arrow indicates a data flow, and a thin solid line arrow indicates a control flow. Reference numeral 40 denotes a module having all processing functions for performing page format setting, which is composed of modules 41 to 46 and buffers 47 to 49.
It is composed of a RAM and an external storage device. When the user executes a page layout (page format) setting command, first, the cursor position saving module 41 saves the current cursor position in the 48 cursor position buffer. This cursor position data is used to analyze the page number set later. Next, the data input module 42 receives the setting value input by the user. The input set value data is stored in the 47 input data temporary buffer. The setting value analysis module 43 analyzes whether or not there is a contradiction in the user's specification.

The page number analysis module 44 checks which page layout (page format) has been set. At this time, the cursor position data saved in the cursor position buffer 48 and the first character position data of the page format data in the document data section (structure) 49 are used. The data access module 45 updates the corresponding page format data. After updating the set values, the entire display of the page is re-displayed by the display module 46 to complete a series of processing for page formatting. Note that the page number analysis module of 44 can be omitted by constantly monitoring the input position (cursor position) designated by the user.

FIG. 5 is a flow chart showing the processing contents of page format setting in the present invention. In this figure, when the user executes the page format setting command,
The "Page format setting" processing routine is called.
The processing routine will be described below. Step 5
In 01, first, the character number at the current cursor position from the beginning of the input data is stored. In step 502, a setting screen similar to a menu format that allows the user to easily set (change) the page format is displayed and waits for the page format to be set.

In step 503, the setting value input by the user is analyzed for contradiction. The analysis here is to execute an error process when a margin or a gap is set such that a page in which no character can be displayed occurs. In step 504, if there is a contradiction as a result of the analysis, the process proceeds to step 508, error processing is executed, and the process ends. The processing up to this point depends on each processing system, and is not specified in this processing method.

If there is no contradiction in the set values, the process proceeds to step 505 to analyze the page number. In step 506, the page format data corresponding to the set page is updated. Here, it is also possible to update all the set values of the format data, for example, only specific data such as column information only. Step 50
In step 7, the entire page is displayed again based on the set page format.

FIG. 6 is a detailed flow chart showing the processing contents of the page number analysis in FIG. As shown in this figure, here, the number of pages of the character at the cursor position is determined while determining the front-back relation between the character at the cursor position and the first character of each page.

In step 601, the page register (p
Set 1 to g). In step 602, the pointer of the format data of the first page is input to the page format storage section (PageFormat section). In step 603, it is determined whether there is page format data on the next page. If there is page format data, the process proceeds to the next step 604, and if not, the page number analysis process ends.

At step 604, if there is page format data, 1 is added to the page register (pg). In step 605, the pointer of the page format data of the next page is input to the page format storage section (PageFormat section). In step 606, the context of the character at the cursor position and the first character of the next page is determined. If the character at the cursor position is before the first character of the next page, the page number analysis process is ended, and if it is after the first character, the process returns to step 603 and the page number analysis process is repeated.

As described above, the character at the cursor position is compared with the first character of the page, so that the context of the first character one page after is always checked. Alternatively,
By storing how many characters can be displayed on each page, it is possible to analyze the page without looking at the first character of the next page.

[0024]

According to the present invention, the layout can be changed on a page-by-page basis, so not only can a document with more expressive power be created, but also the work at the time of document creation can be reduced. it can.
