Abstract

PURPOSE:To comprehend the nest relation among blocks or groups at a glance even when any program of a deep nest level is copied out fair by increasing or reducing the next level and outputting this level to a list when the block and group nest levels are deepened. CONSTITUTION:An input program text 7 is decomposed into each sentence via a sentence setting means 1, and the program images of the sentences excluding the undesired immediately preceding blank are successively set to the sentence information stored in a sentence information table 8. A sentence information table setting means 2 is started after an end code to the sentence information. Then the information on the switching stage number is inputted via an external parameter 10 and at the same time a nest level switch deciding means 3 is started to decide whether the sentence information on the table 8 has the end code or not. If not, the sentence information, the nest level information, and the sentence title information are taken out of the table 8 and sent to a nest level increasing process means 4 and a nest level reducing process means 5. Then these information are displayed on a list 9 after a prescribed process.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram configuring an embodiment of the present invention.

The program cleanup processing method of this embodiment includes a sentence setting means 1, a sentence information table setting means 2, a nest level switching judgment means 3, a nest level rounding up processing means 4, a nest level rounding down processing means 5, and a list output. It is composed of a means 6, a program text 7, a statement information table 8, a list 9, and an external parameter 10.

FIG. 2 is a flowchart showing the operation of the text information table setting means 2 in FIG.

The second figure is a flowchart showing the operation of the nest level switching determination means 3 in FIG.

FIG. 4 shows details of the sentence information table 8.

The sentence information table 8 is composed of sentence information indicating program image information of the sentences constituting the program text 7, nesting level information indicating the nesting level of this sentence, and sentence type information indicating the type of this sentence. .

FIGS. 5(Ht) and 5(b) are examples of lists output when the present invention is applied to a source program written in the PL/I language.

Next, the overall operation of this embodiment will be specifically explained.

The sentence setting means 1 inputs the program text 7, decomposes all the program texts 7 into sentence units, and sets program images of the sentences one after another, excluding the immediately preceding extra blanks, to the sentence information in the sentence information table 8. , when finished, sets an end code to the sentence information in the sentence information table 8, and starts the sentence information table setting means 2.

The sentence information table setting means 2 is activated by the sentence setting means 1, and after the processing shown in FIG. 2 is completed, the nest level switching determination means 3 is activated.

The operation of the sentence information table setting means 2 is shown in FIG. Here, let A be data indicating the nesting level of a sentence.

In step C2, A is set to an initial value of 0. Step C3
It is determined whether the sentence information in the sentence information table 8 set by the sentence setting means 1 is an end code, and if it is an end code,
Since the processing of the sentence information of all the sentence information tables 8 has been completed, the process is terminated at step C4, and if the code is not an end code, control is passed to step C5. Next, in step C5, the sentence information from the sentence information table 8 is extracted. Next, in step C6, the sentence information table 8 extracted in step C5
It is determined whether the sentence information is the start sentence or end sentence of a block or group or something else, and the sentence type information of the sentence information table 8 corresponding to this sentence information is set. Next, in step C7, it is determined whether the sentence type information in the sentence information table 8 set in step C6 is the end sentence of a block or group, and if so, control is passed to step C8, and if not, control is passed to step C8. Transfer control to C9. next,
In step C8, since the sentence information in the sentence information table 8 extracted in step C5 is the end sentence of the block or group, the value of A is decremented by 1 and control is passed to step C9. In step C9, the value A is set in the nest level information area of the sentence information table 8 corresponding to the sentence information in the sentence information table 8 extracted in step C5. Next, in step CIO, it is determined whether the sentence type information in the sentence information table 8 set in step C6 is the start sentence of a block or group, and if so, control is passed to step C11,
Otherwise, control is passed to step C3 and the subsequent processing is repeated. Next, in step C1l, since the sentence information in the sentence information table 8 retrieved in step C5 is the start sentence of a block or group, the value of A is incremented by 1, and step C3 (j control is passed and subsequent processing repeat.

The nest level switching determination means 3 is activated by the sentence information table setting means 2 and manually inputs information on the number of switching stages from an external parameter 10. The operation of the nest level switching determination means 3 is shown in FIG.

In step D2, it is determined whether the sentence information of the sentence information table 8 set by the sentence setting means 1 is an end code, and if it is an end code, the processing of the sentence information of all the sentence information tables 8 has been completed. Therefore, the process ends in step D3, and if the code is not an end code, control is passed to step D4.

Next, in step D4, sentence information, nest level information, and sentence type information from the sentence information table 8 are extracted. Next, based on the sentence type information extracted in step D4, step D determines whether it is the start sentence or end sentence of a block or group, and if so, passes control to step D6,
Otherwise, control is passed to step D8. Next, in step D6, the remainder obtained by dividing the value of the nest level information of the sentence information table 8 retrieved in step D4 by the value of the number of switching stages is set to B, and in the next step D7, the value of the number of switching stages is calculated. It is determined whether the -1 value and B are equal, and if they are equal, control is passed to step D9, and if not, control is passed to step D8. Step D8 starts the list output stage f 6 in order to output the sentence information of the sentence information table 8 extracted in step D4 to the list 9, and then passes control to step D2 and repeats the subsequent processing. Step D
In step 9, it is determined whether it is the start sentence of a block or group based on the sentence type information in the sentence information table 8 taken out in step D4, and if so, control is passed to step DIO, otherwise control is passed to step DI2. give. In order to round up the nest level in step D10, step D
In order to output the sentence information of the sentence information table 8 retrieved in step 4, the list output means 6 is activated, and then control is passed to step Dll. In step D11, the nest level rounding up processing means 4 is started in order to output a nest level rounding up display, and then control is passed to step D2 and the subsequent processes are repeated. In step D12, the nest level devaluation processing means 5 is activated to output a nest level devaluation display in order to devalue the nest level, and then control is passed to step D13. In step D13, the list output means 6 is started in order to output the sentence information of the sentence information table 8 extracted in step D4, and then control is passed to step D2 and the subsequent processes are repeated.

The nest level rounding up processing means 4 uses the sentence information table 8.
When outputting sentence information to List 9, if it is determined that it is necessary to output the nesting level rounded up display,
It is activated by the nest level switching determining means 3 to calculate the next values of E and F from the nest level information values of the sentence information table 8 extracted by the nesting level switching determining means 3 in order to output a nest level round-up display. .

E- (nest level) +1 F-E- (number of switching stages) +1 Next, from the beginning of the area where the clean-written program is output,
Output the number corresponding to the number of switching stages by enclosing the number +1 to the value of E to the setting list 9, and then add the number +1 to the value of E at the beginning of the area where the cleaned up program is output. Set the circled characters and output them to List 9. When outputting the sentence information in the sentence information table 8 to the list 9, the nest level devaluation processing means 5 executes the nest level change determination means 3 when it is determined that it is necessary to output a devaluation display of the nest level. The next G and H values are determined from the nest level information values in the sentence information table 8 in order to output a nest level devaluation display.

G- (nest level) +1 H-G- (number of switching stages) +1 '/I! G at the beginning of the area where the program is output after the f file
Set a circled number that is +1 to the value of H, and output it to List 9. Next, set a circled number that is +1 to the value of H from the beginning of the area where the cleaned up program is output. Set characters for the number of columns and output to list 9.

The list output means 6 includes the nest level switching determination means 3.
It is activated in order to output the sentence information of the sentence information table 8 extracted in the ξ list 9 after the cleanup, and the value of the nest level information of the sentence information table 8 is switched from the beginning of the area where the program after li'i4F is output. Vertical lines are set by the value of the remainder after dividing by the number of columns, and immediately after this, the sentence information in the sentence information table 8 is output to the setting list 9.

[Effects of the Invention] As explained above, the present invention is capable of rounding up the nesting level when the nesting of blocks and groups becomes deep in the process of formatting and outputting the nested relationships of blocks and groups of a source program in an easy-to-read list. By rounding down and outputting to a list, the relationship between the nesting of blocks or groups can be improved, no matter how deep the program is written. is displayed, which has the effect of allowing you to understand the nesting relationships of blocks or groups at a glance.
