The operation of an embodiment of the present invention will be explained using FIG. The document to be edited is stored in an external storage device holding the information shown in FIGS. 2 and 3, and when the program is started, each of the block management means 1 and text storage means 2 is stored in the area. When the program ends, the document information stored in the respective areas of the block management means 1 and text storage means 2 is stored in the external storage device.

The display format in the structure display means 4 is, for example, as shown in FIG.
), (B).

The structure display means 4 displays the structure of the document on the CRT screen according to the following procedure.

The structure display means 4 stores the internal number of a text block whose value stored in the parent code storage area 12 in the block management means 1 is NULL in an internal buffer (B F
In step A) of FIG. 6, the following process (I) is performed until the value set in the internal buffer (BFF) becomes NULL (step B of FIG. 6).

(I) Match the character string stored in the heading name storage area 17 of the text block corresponding to the internal number set in the internal buffer (B F F) to the value stored in the level storage area 15. (Step C in Figure 6). The internal number set in internal buffer y (BFF) is set in internal buffer 1 (B'FFI), and the first child code storage area 14 corresponding to the internal number set in internal buffer (BFF) is The value is set in the internal buffer (BFF) (step D in FIG. 6). However, if the value of the first child code storage area 14 is NULL, the value of the right brother code storage area 13 of the internal code set in the internal buffer 1 (BFFI) is transferred to the internal buffer (B F F). (Steps E and F in Figure 6). If the value of the right brother code storage area 13 set in the internal buffer (B F 1
(BFFI), and the value of the right brother code storage area 13 of the parent code is sent to the internal buffer (BFF) (steps G and H in Figure 6). If the value of the right brother code of the parent code is NULL, internal buffer 1 (BFFI
) If the parent code of the internal number set in ) is NULL, NULL is set in the internal buffer (BFF) and the process ends (step LJ in FIG. 6).

The display form of FIG. 5(B) is obtained by the user specifying one node using the command input means 3 of FIG. 1 in FIG. 5(A), and displaying the child nodes of the specified node. Realized.

The editing processing means 5 obtains an editing process name (for example, grouping), an internal number added to the text block to be edited, and a name given to the grouped set from the command input means 3 (step A in FIG. 7A). ), here the text block to be grouped (g 1
．． g2. ..., gn) all have the same parent (
p g) and are of the same level. Text blocks to be grouped (gl, g2.
, gn) is set in the internal buffer (BF) (step B in FIG. 7A). Right older code storage area 13 of the text block with the internal number set in the internal buffer (BF)

According to the value set in , the following processing is performed (step C in FIG. 7A).

(1) The internal number set in the internal buffer (BF) is the text block (gl, g
2. ..., gn) (Steps D to ■ in Figure 7A) ■If no value is set in save buffer 1 (SBI), use the internal number set in the internal buffer (B F). The save buffer 1 (SBI) and the first child code storage area 14 of the parent code (pg) are saved.

■When a value is set in save buffer 1 (SBI) The internal code of the text block set in the internal buffer (BP) is set to Set it in the right brother code storage area 13. internal buffer
The internal number set in (BF) is saved in the save buffer (SB).
At the same time, the value of the right-hand older code storage area 13 of the text block having the internal number set in the internal buffer (BF) is set in the internal buffer (BF).

(2) The internal number set in the internal buffer (BF) is the text block (gl, g
2. ..., gn) (Steps D and I in Figure 7A, Step J NM in Figure 7B) ■If a value is not set in save buffer 2 (SB2), the internal buffer (BF) is The set internal numbers are set in save buffer 2 (SB2) and save buffer 3 (SB3).

■When a value is set in the save buffer 2 (SB2) The internal code of the text block sent to the internal buffer (BF) is sent to the save buffer sofa 2 (SB2).
The code is set in the right-hand older code storage area 13 of the text block having the internal number written in . Save the internal number set in the internal buffer (BF) to save buffer 2
(SB2) and the internal buffer (SB2).
The value of the right brother code storage area 13 of the text block with the internal number set in BF) is transferred to the internal buffer (
BF)

Next, an area (NG) is secured in the block management means 1 to store information regarding a new name given to a set of grouped text blocks (step N in FIG. 7B). Assign a new internal number to the NG code storage area 11 (step O in Figure 7B), and save buffer 1.
The new internal number stored in the NG code storage area 11 is set in the right older code storage area of the text block with the internal number set to (SBI).

Furthermore, the internal number of the parent (pg) is set in the parent code storage area 12, NULL is set in the right brother code storage area 13, and the save buffer 3 is set in the first child code storage area 14.
Set the internal number of the first child of the text block to be grouped stored in (SB3), and set the same text block as the text block with the internal number stored in the shelter sofa (SBI) in the level storage area 15. A pointer to the text block corresponding to the level number is stored in the pointer area 16, a newly named name is stored for the set of text blocks grouped in the area, and a new name for the grouped text block is stored in the heading name storage area 17. Store the newly named name in the set (
Step P in Figure 7B).

Next, NULL is set in the sibling code storage area of the text block to be grouped stored in the save buffer 2 (SB2) (step Q in FIG. 7B).

The document display means 6 stores the internal number of the text block whose value stored in the parent code storage area 12 in the block management means 1 is NULL in an internal buffer (BF).
