Abstract

A document editing system for storing a plurality of format data records in a tree structure which define the format of a document. The format data records comprise any combination of a title field, a basic field, and a group field. A document data management section, in response to a document preparation request from a work station, prepares a basic document having a tree structure consistent with the document format data records. Furthermore, the document data management section updates the basic document with externally input data to prepare a target document. The document data management section determines the number of lines and characters per line of a group field including a line/character increase or decrease field, from a tree structure subordinate to the group field.

Claims

4. A system for editing document data according to claim 3, wherein said flag comprises at least one of the following flags:

(a) a copy flag for indicating that the field can be copied in the document data;

(b) a position flag for specifying the fields subordinate to a larger field and for designating the expansion or contraction of the subordinate fields in a horizontal direction and in a vertical direction before these fields are displayed or printed;

(c) a division flag for indicating whether the entire data to be printed in the field should be printed on the next page, or whether only the over-flowing portion of the data should be printed on the next page; and

(d) a title-printing flag for indicating whether or not a title should be printed in the corresponding title field.

5. A system for editing document data according to claim 1, wherein the internal tree structure of said stored document format-data comprises a plurality of logic pointers which define the relationship of document data records which correspond to the fields of the document data.

6. A system for editing document data according to claim 5, wherein each of said document data records has a first item used to set a first code specifying the type of the field corresponding to the document data record, a second item used to set an ID code specifying a data format record corresponding to the document data record, a third item used to set the number of lines to be displayed or printed in the field, a fourth item used to set the number of digits per line, a fifth item used to set a flag representing the nature of the field, a sixth item used to set the number of a screen control record corresponding to the document data record, and a seventh item used to set a respective one of said logic pointers representing the relationship between the field and the document data record.

7. A system for editing document data according to claim 6, wherein said flag comprises at least one of the following flags:

(a) a copy flag for indicating that the field can be copied in the document data;

(b) a position flag for specifying the fields subordinate to a larger field and for designating the expansion or contraction of the subordinate fields in a horizontal direction and in a vertical direction before these fields are displayed or printed;

(c) a division flag for indicating whether the entire data to be printed in the field should be printed on the next page, or whether only the over-flowing portion of the data should be printed on the next page; and

(d) a title-printing flag for indicating whether or not a title should be printed in the corresponding title field.

8. A system for editing document data according to claim 1, further comprising:

document display means for displaying the document data;

screen display format data storage means for storing screen display format data arranged into said tree structure in order to display on said document display means the document data organized into said tree structure; and

screen display means, coupled to said document data storage means, said screen display format data storage means, and said document display means, for displaying, in a hierarchical structure, the document data arranged in a hierarchical structure in accordance with the screen display format data stored in said screen display format data storage means.

9. A system for editing document data according to claim 8, wherein one record of said screen display format data corresponds to one record of the document data, and said screen display format data record has a first item used to set a first code specifying the type of the field corresponding to the display format data record, a second item used to set an ID code specifying one of the fields of the document data which corresponds to the screen display format data record, a third item used to set the level of said field corresponding to the screen display format data record, a fourth item used to set the number of lines to be displayed and printed in said corresponding field, a fifth item used to set the number of digits per line, a sixth item used to set a flag representing the nature of said corresponding field, a seventh item used to set the display-starting position of said corresponding field, and an eighth item used to set a field pointer specifying the one of the fields of said document file which corresponds to the screen display format data record.

10. A document-editing system according to claim 9, wherein said first code, said ID code, said level of a field, said number of digits per line, and said flag, which all are set in the items of the screen control data record, are copied from the data which are set in the items of the document-data record corresponding to the screen display format data record;

and when said first code specifies a title field, the number of lines set in said fourth item is copied from the number of lines set in the format-data record corresponding to the screen control data record, when said first code specifies a basic field, the number of lines is determined by the amount of data set in that item of the corresponding document-data record which is used to set a pointer, and when said first code specifies a group field, the number of lines is determined by the total number lines of the fields subordinate to the group field.

11. A system for editing document data according to claim 1, wherein a document format-data record defining said document format data has a first item used to set a first code specifying the type of field corresponding to the document data record, a second item used to set an ID code specifying one of the fields of the document data which corresponds to the document format-data record, a third item used to set the level of the specified field, a fourth item used to set the number of lines to be initially displayed or printed in the corresponding one of the fields, a fifth item used to set the number of digits per line, a sixth item used to set a flag representing the nature of the specified field, and a seventh item used to draw field-framing lines defining the specified field.

12. A system for editing document data according to claim 11, wherein said document format-data record includes an eighth item for designating a line of characters to be displayed and printed as title data, when the code set in said first item specifies a title field.

13.

and when said first code specifying the type of the document-data record specified initial data, said document-data management means writes said initial data in said document file, and sets a pointer indicating the storage location of said initial data, in an item of the document-data record which is stored in the document-data storage means and corresponds to the basic field immediately preceding the document-data record corresponding to the format-data record input to the document-data management means.

14. A system for editing document data according to claim 1, wherein a document format-data record defining said document format data has a first item used to set a first code specifying the field corresponding to the format data record, a second item used to set an ID code specifying the one of the fields of the document data which corresponds to the format data record, and a third item used only when the first code set specifies initial data and is used to specify data to be input to the corresponding field as an initial value.
