Abstract

PURPOSE:To facilitate management by managing translating information at the time when a source program is translated and option information in a source program file. CONSTITUTION:By designating a name of a source program 12 at the time of starting a compiler 2, an option information input means 21 inputs an option at the time of translation inputs from option information of translating information stored in a source program file 1. An error deciding means 22 decides whether an error exists or not by referring to the number of errors of the translating information stored in the source program file 1 before executing the translation. When an error exists, an error information output means 23 outputs error information stored in the source program file 1 to an error output file 4 and ends a processing of the compiler 2, and when no error exists, a translating information updating means 24 shifts a control to a translating means 25, and after the translation is ended, the translating information in the source program 1 and the error information are updated to the latest information. In such a manner, the management is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for managing translation information output when a source program is translated.

[Conventional technology]

In a compiler, translation information including error information is output to -S when a source program is translated. Conventionally, one translation information is a translation list or user output file/error output file, etc. It was supposed to be output to .

On the other hand, information necessary for translation is input as an option, and the information must be entered by the user each time translation is performed.

[Problem to be solved by the invention]

Conventional compilers use the above method,
Therefore, there were the following drawbacks.

■Since the file where translation information is output and the file where the source program is stored (source program file) are separate, always ensure a translation list or user output file/error output file, etc. to obtain translation information. Management is complicated and troublesome.

■Even if there is a source program that contains an error, the translation is executed as usual without making any judgment during translation, which may result in unnecessary compilation processing, increasing compilation time.

■If you want to translate the same source program multiple times while making modifications, you should create a JCL or command file for translation in order to input the information necessary for translation, or use a command that includes options at the time of translation. The only option is to enter the key directly, and the operability is very poor.

The present invention has been proposed in view of the above points, and its purpose is to provide a source program in which translation information can be managed and effectively used within a source program file, and in which it is easy to input optional information. The objective is to provide a file translation information management method.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an area in a source program file to store translation information and error information including option information and the number of errors. shall be cleared to zero, and an option information manual means for inputting options at the time of translation from the obscene information of the translation information by specifying the name of the source program at startup in the compiler, and error detection of the translation information before execution of translation. error determining means for determining whether or not there is an error by referring to the number; and error information output means for outputting the error information to the error cuff file and terminating the processing of the compiler when it is determined that there is an error. Translation information updating means is provided, which transfers control to the translation means when it is determined that there is no error, and updates translation information and error information in the source program file to the latest information after the translation is completed.

[Effect]

In the source program file translation information management method of the present invention, by specifying the name of the source program when starting the compiler, the option information input means inputs options at the time of translation from the translation information stored in the source program file. The error determination means refers to the number of errors in the translation information stored in the source program file before translation execution, and determines whether there are any errors. If it is determined that there is an error, an error occurs. The information output means outputs the error information stored in the source program file to the error file to terminate the compiler processing, and when it is determined that there is no error, the I11 translation axis information means controls the translation means. Transfer! ■
After translation is complete, update the translation information and error information in the source program file to the latest information.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a source program file translation information management method according to the present invention.

In FIG. 1, l is a source program file in which a source program 12 is stored, and in addition to the source program 12, option information 111 and error number 11 are stored.
Translation information fall including 2 and error information 13 are stored.

Here, the option information 111 is information necessary for translation, and the number of errors 112 is information about the number of errors that occurred during the previous translation. It is assumed that the number of errors 112 is cleared to zero (set to a state where there are no errors) when the source program 12 is updated or corrected, and the error information 13 is information related to errors that occurred during the previous translation.

On the other hand, 2 is a compiler that translates the source program 12, and in addition to the translation means 25 that executes the translation, by specifying the name of the source program 12 at the time of startup, the translation information 11 of the source program file l can be used to select translation options. Option information input means 21 that inputs the option information from the option information $Ia 111, and error determination means 22 that determines whether there is an error by referring to the number of errors 112 in the translation information [11] of the source program file l before translation execution.
and an error information output means 23 that outputs error information 13 of the source program file 1 to an error output file 4 to terminate the processing of the compiler 2 when it is determined that there is an error; and when it is determined that there is no error. Translation information updating means 24 is provided which transfers control to the translation means 25 and updates the translation information 11 and error information 13 of the source program file 1 to the latest information after the translation is completed.

Further, 3 is an object file that stores an object program that is a translation result.

Figures 2, 3, 4 and 5 are respectively
This is a flowchart showing the processing of the option information input means 21, the error determination means 22, the error information output means 23, and the translation information update means 24 in the figure.
The operation of the embodiment will be explained with reference to FIGS.

First, when updating or modifying the source program 12, the user uses the translation information 11 of the source program file 1.
The number of errors 112 is cleared to zero, and when translating, specify the name of the source program 12 and start the compiler 2. In the compiler 2, the option information input means 21 is activated first.

The activated option information input means 21 inputs the option information 11 of the translation information 11 of the source program file l.
1 is read (step S3 in FIG. 3), processing is performed assuming that it is the option specified at the time of translation, and then the error determination means 22 is activated (step S2).

The activated error determination means 22 reads the number of errors 112 in the translation information 11 of the source program file 1 (step S3 in FIG. 3), and determines whether there are any errors (step S4).

As a result of the determination, if it is determined that there is an error, the error information output means 23 is activated and control is transferred (step S5).

The activated error information output means 23 inputs the error information tl13 of the source program file l and outputs it to the error output file 4 (step S7 in FIG. 4), and ends the processing of the compiler 2 (step S8).

On the other hand, if there is no error as a result of the determination in step S4 in FIG. 3, the translation means 25 is activated and control is transferred (
FIG. 3 step S6).

The activated translation means 25 translates the source program 12 of the source program file 1, generates the object file 3, and then activates the translation information updating means 24 to transfer control.

The activated translation information updating means 24 updates the translation information 11 of the source program file 1 according to the translation result of the translation means 25 (step S9 in FIG. 5), and identifies whether or not there is an error during translation. ), if there is an error as a result of m, the error information It! of source program file 1 is displayed. 13 updates (step S
l l) If there is no error, delete the error information 13 of the source program file 1 (step 51).
2).

Then, the processing of the compiler 2 is terminated.

In this way, by registering the translation information at the time of translation in the source program file l, it is possible to easily perform an efficient translation based on this registered information when translating again.

〔Effect of the invention〕

As explained above, in the source program file translation information management method of the present invention, the translation information and option information when the source program is translated are managed within the source program file, so that: ■ Translation Since information can be managed in the source program file-book, there is no need to secure translation lists, user output files/error output files, etc. (this makes management very easy).

■Even if there is an error due to omission of correction in the source program, the previous error information is checked during translation and the translation process is interrupted, eliminating unnecessary compile processing.

■Easy to use because you don't have to specify options every time you translate.

There are effects such as
