Abstract

PURPOSE:To shorten the useless executing time by optionally continuing or discontinuing a process when a language process program has a specific error or the error occurring frequency exceeds the designated maximum level. CONSTITUTION:It is checked whether the error occurring frequency exceeds the designated maximum level or not. If so, the control is shifted to a program abnormality end processing part 11. If not, it is checked whether the received error number is equal to the designated one or not. If so, the information showing whether the error number designated the continuation or discontinuation of the process is extracted. When the continuation of the process is designated, an error process part 10 performs the post-process or an error and returns the control to an object program production part 4. While the control is returned to the process 11 when the discontinuation of the process is designated. As a result, the useless executing time is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a language processing program, and more particularly, to a language processing program that continues/interrupts processing according to the occurrence of an error during execution.

[Conventional technology]

Conventionally, when an error occurs in a language processing program during execution, it is not possible to specify error handling for the language processing program. Therefore, even if an error that the user considers to be a fatal error occurs and processing is not interrupted, execution cannot be interrupted.

[Problem to be solved by the invention]

In the conventional method described above, even if a user wants to interrupt processing due to an error that is determined to be a fatal error, processing is interrupted because it is not possible to specify error handling to the language processing program. Errors must be corrected after the program has run to completion. Therefore, there is a drawback that the execution time from the occurrence of an error that the user considers to be fatal until the program ends is wasted.

Conversely, even if an error occurs that the user determines is not fatal and would like the user to continue with the process,
Since error processing cannot be specified for the language processing program, the processing cannot be continued, and there is also the drawback that it is impossible to obtain the results of language processing after the point where the error occurs.

In particular, when macro processing is combined, the severity of errors varies depending on the user's source program, but predetermined error processing may waste execution time or cause object 1-files to be lost. The disadvantage is that there is a high possibility that it will not be possible.

The purpose of the present invention is to continue processing in the event of an error.
An object of the present invention is to provide a language processing program that specifies interruption.

[Means to solve the problem]

The language processing program of the present invention can be executed by inputting an error number, a designation for continuing/suspending processing when the error occurs, and the maximum number of errors that can occur in a file or command line. If an error occurs during execution, a check is performed to see if the number of errors that have occurred exceeds the specified maximum number, and whether it is the specified error, and the number of errors that have occurred is determined to be the specified maximum number. If it is detected that the error number exceeds the specified error number or that the error that has occurred matches the specified error number, the subsequent processing is continued or interrupted as specified.

〔Example〕

Next, the present invention will be explained based on the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention. In the figure, the language processing program 2 includes an input processing section 3 for a source program file 1, an object program generation section 4, an object program file output section 5, a program termination processing section 6, and a console 7.
It has an error specification processing section that reads and processes the error specification file 8 in response to an instruction from the language processing program 2, an error processing section 10, and a program abnormality processing section. .

Before reading the source program file 1, the language processing program 2 uses the error specification processing unit 9 to input an error number and process from the console 7 or the error specification file 8 to continue or interrupt the process specified when an error occurs. Specification 9 The maximum number of errors that can occur is read and the data is passed to the error processing unit 1o. Next, the source program file 1 is read by the input processing section 3 and the data is passed to the object program generation section 4.

The object program generation unit 4 generates a source program.
An object program is generated from the file 1, and the object program file output section 5 and program termination processing section 6 output the generated object program to the object program file 12.

If an error occurs during execution of the object program generation section 4, information on the error number that has occurred is passed to the error processing section 1o.

FIG. 2 is a flowchart showing the operation of the error processing section 10.

In the same figure, the error processing unit 10 that has received the error number information performs a power run I/up 13 of the number of errors that have occurred.

Next, a comparison 14 is made to see if the number of errors that have occurred exceeds a specified maximum number of errors that can occur, and if it does, control is passed to the program abnormal termination processing section 11.

If the error number is exceeded, the receiver performs a comparison 15 to see if the received error number is the designated error number.

If it is the specified error number, information is collected 16 as to whether the error number specifies whether to continue or interrupt the process. If continuation of the process is specified, the error processing unit 10 performs error post-processing 17 and returns control to the object program generation unit 4. Conversely, if the interruption of processing is specified, control is returned to abnormal termination processing 11 of the program.

If the error number is not specified, normal error processing 18 is performed.

The above processing operation is repeated until the source program file 1 is read, and finally the program termination processing section 6
Performs post-processing to terminate the program and ends the program execution.

As described above, when a specific error occurs or when the number of errors that occur exceeds a specified maximum number, it is possible to specify whether to continue or interrupt the processing of the language processing program.

FIG. 3 is a block diagram showing a second embodiment of the present invention. In the figure, the language processing program 2a includes an error processing section 10a, and specifies continuation/interruption of processing in an interactive manner when an error occurs via the console 7a. That is, before execution, you can specify only the error number and the maximum number of possible errors for which you want to continue or interrupt processing when an error occurs, and then specify whether to continue or interrupt processing from the console when an error occurs. Other functions are the same as in the first embodiment.

If an error occurs during execution of the object program generation section 4 of the language processing program 2a, information on the error number that has occurred is passed to the error processing section 10a.

FIG. 4 is a flow chart showing the operation of the error processing section 10a. In the same figure, the error processing section 10a that has received the error number information counts up the number of errors (13).

Next, a comparison 14 is made to see if the number of errors that have occurred has exceeded the specified maximum number of errors that can occur, and if it has, the console displays/input processing 19a tells the console whether to continue or interrupt the process. A state of waiting for an input is displayed, and if the input of any designation is accepted, the designation 16a is followed. If continuation is not specified, control is transferred to comparison 15 to see if it is the specified error number.

If suspension is specified, program abnormal termination processing 11
Return control to.

If the number of errors that have occurred does not exceed the maximum number, the receiver performs a comparison 15 to see if the received error number is the designated error number. If it is the specified error number, in the console display/input processing 19a, the console displays a state waiting for an input on whether to continue or interrupt the process, and if either specified input is accepted. , according to its specification 16a. If there is a continuation designation, control is returned to the object program generation section 4 via error post-processing 17. Conversely, if interruption is specified, control is returned to program abnormal termination processing 11.

If the error number is not specified, normal error processing 18 is performed.

The above processing operation is repeated until the reading of the source program file 1 is completed, and finally, the program termination processing section 6 performs post-processing to terminate the program, and the execution of the program is terminated.

As described above, when a specific error occurs or when the number of errors that occur exceeds the specified maximum number, it is possible to specify whether to continue or interrupt the process at the point at which the error occurs.

〔Effect of the invention〕

As explained above, the present invention allows processing to be continued/interrupted at will when a specific error occurs in a language processing program or when the number of errors exceeds a specified maximum number. This has the effect of allowing the user to immediately interrupt processing to save wasted execution time, or conversely to continue processing and eliminate all errors.
