Abstract

PURPOSE:To find an error in its early stage and to shorten the time of program developing operation by inputting the block identifier and block position of an optional block to be edited which is specified by a user in an editor during the editing operation of a source program. CONSTITUTION:An upper-limit and a lower-limit token (identifier) which indicate the range of the block to be processed during the editing of the editor are specified and the depth (nest level) of the block to be edited in the outermost block is specified to determine the block specification range to the lower-limit token by moving a cursor to the upper-limit position. Then only the specified block is extracted as an editing image plane and the editing of only the specified block is enabled. Consequently, an error is found in its early stage and the program development time is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a designated block editing method for an editor, and particularly to a C source program editing method.

[Conventional technology]

In conventional program editing, block descriptions that allow nesting in a source program, for example, in a C source program description, ゛(′ and ′)′, ゛(” and ゛)″, “/
*″ and °’ * / ” and “#if d e f
It is necessary to check the validity of parts enclosed in or associated with block identifiers such as compiler control directives such as The structure is checked visually, which takes time and may result in checking errors.

[Problem to be solved by the invention]

In conventional program editing, block descriptions that allow nesting in a source program, for example, in a C source program description,
′, “= / *l= and I */ ” and '#1fd
The validity of parts surrounded by or associated with block identifiers such as compiler control directives such as "ef" is checked by visually inspecting the nested block structure in the entire series of source programs. The disadvantage is that the check takes time and mistakes can be made.

It also performs a syntax check by compiling.
Even in this case, there is a drawback that it is difficult to discover errors in the block description when the balance of the block structures coincides by chance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a specified block editing method for an editor that can eliminate these drawbacks, detect errors at an early stage, and shorten the time required for program development work.

[Means to solve the problem]

The configuration of the specified block editing method of the present invention is that upper and lower tokens (identifiers) indicating the range of blocks to be processed are specified during editing by the editor, and the block to be edited is at the depth of the outermost block. By specifying the (nest level), move the cursor to the upper limit position to confirm the block specification range up to the corresponding lower limit token, draw only this specified block as an editing screen, and select the specified block. The feature is that only the content can be edited.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a flowchart illustrating one embodiment of the present invention.

In the specified block editing method of this embodiment, in step 1, upper and lower tokens (identifiers) indicating the range of blocks are specified in the nibut, then in step 2, the nesting level of the block is specified, and these After completing the input operation,
In step 3, the upper limit block identifier and the corresponding lower limit block identifier that match the nesting level of the input block are found, in step 4 the range of the block is determined and displayed in reverse video or in color, and in step 5
This allows you to edit only the specified block on the editing screen.

Figures 2 (a) to (f) are display diagrams of examples of screen displays in the edit state and when the C source program is not loaded into the editor in order to explain Figure 1, and Figure 3 explains the flow of the program. This is a flowchart.

First, in step A1, the C source program is loaded into the editor as shown in Figure 2 (a>), and this input state or state 11 in the middle of editing is shown.Next, in step A1, a key is pressed to set the input mode of the specified block. is input, and a small window 12 is displayed in step A2.The upper limit of the block (BEG IN B) is displayed in the small window 12.
LOCK ) and a token (identifier) representing the lower limit (END BLOCK ) (step A2.A
3). In this example, the upper limit of the block is ``('' and the lower limit is ゛)''. Here, a guidance message 13 for prompting input is shown in the small window 12 (Fig. 2(b)). .

When the input is completed, the position of the nesting level of the block is specified by moving the cursor display 14 in steps Bl and B2, and the cursor display jumps to the block identifier indicating the upper limit of the neighborhood using the arrow keys, and moves to the block of the corresponding lower limit. Determine the area up to the identifier (determine the block to be edited). This operation is performed to determine the depth (nesting level) of the specified block in the outermost block (steps B3 and B4).

Next, the block range found in step C1 is the block to be edited, and this portion is displayed in reverse 15 (or in color) (FIG. 2(C)).

After displaying this inverted part, by inputting any key in steps Di and D2, only the block 16 to be edited is displayed as shown in FIG. 2(d).Step D3)
The mode becomes editable.

Here, this part is edited/corrected, and the part becomes in the final state 17 (FIG. 2(e)).

Here, by inputting the key to set the input mode of the specified block again in steps El and E2, all sources are
The display state of the program is switched (Fig. 2 (f),
End the operation in this case.

〔Effect of the invention〕

As explained above, the present invention allows inputting the block identifier of the block to be edited and the block position (nesting level) for any block specified by the user in the editor during source program editing work. By doing so, the validity of the block to be edited is checked and edited, and correspondence errors in blocks that are difficult to find can be discovered at an early stage, thereby making it possible to shorten the time required for program development work. In addition, when editing a large amount of source programs, when handling only the blocks that the user needs, it is easy to modify and edit source programs by eliminating the need for unnecessary page turns and key operations such as search operations. It also has the effect of being able to
