Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention monitors the date of execution in order to limit the date on which the contents of processing are valid in business processing by a computer program, and after that date, the program executes the processing. The present invention relates to a processing method for generating a deadline-limited program for performing business processing by providing such a monitoring function when the execution is prohibited.

[0002]

2. Description of the Related Art Regarding a computer program, the processing content related to the computer program is limited to a certain period after a certain date due to the limitation of the license period according to the usage contract or the tax system modification or revision. Due to reasons such as the need to change, the date when the program can be executed and used may be limited as is known.

In such a case, as a part of such a business processing program, there is constant data representing a limited date in the program, the current date of execution is monitored, and when the predetermined date has passed, The above-mentioned object can be achieved by adding a control function program that suspends the execution and starts the business processing only within the deadline.

However, the processing of a certain task and the processing of the deadline limited control, which has nothing to do with the processing content,
When incorporated in such an integrated program, an error that adversely affects the other process often occurs during maintenance of one process, and the reliability is likely to be impaired.

Moreover, it is often necessary to revise the limited date due to renewal of contract, change of system modification schedule, misconception or the like. An object of the present invention is to provide a date limited program generation processing method capable of generating a date limited program so as to easily maintain reliability.

[0006]

FIG. 1 is a flow chart of processing showing the configuration of the present invention. The figure shows the configuration of the date-limited program generation processing method. In order to limit the use of the required business processing program to the use until the required date, the date of the execution is monitored when the business processing program is executed. By providing the function for identifying whether or not to execute the program in the business processing program, and creating the deadline-limited program, the monitoring program and the business processing program are individually created as independent programs (processing step 1 ,
2).

After the object modules of the business processing program and the monitoring program are individually generated (processing steps 3 and 4), both the object modules are combined and edited to execute the load module of the due date limited program. (Processing step 5).

The monitoring program is a program defined to compare the due date held in itself with the date obtained from the operating system and to activate the business processing program only when the date does not exceed the due date. To provide.

[0009]

According to the present invention, a monitoring program for performing a deadline-limited control is created as an independent source program separate from the business processing program, and both source programs are individually compiled or assembled to generate respective object modules. To do.

The object modules are combined and edited by a so-called link edit process to form a load module capable of executing the target date limited program.

Therefore, it is sufficient to modify the program for each source program, regenerate the object module only for the modified program, and combine it with the object module of the other unmodified program.

Therefore, the risk of accidentally changing one modification to the other is eliminated. The monitoring program compares the due date held in its own program with the date acquired from the system clock function, etc.
Only when the current date does not exceed the due date, the program is defined to start the business processing program. When the current date exceeds the due date, an appropriate message is output and execution of the program is interrupted.

If necessary, the monitoring program can be activated to start a second business processing program different from the above-mentioned business processing program when the current date exceeds the due date. In addition, a second business processing program is created, and the monitoring program, the business processing program for which the deadline is limited, and the second business processing program are incorporated into the date limited program by the combined editing.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a diagram showing an example of the flow of processing of a monitoring program. In FIG. 2 (a), if the deadline is within the deadline, the combined business processing programs are operated, and when the deadline passes, the This is the case when the job is canceled, and (b) is the first within the due date.
In this case, the second business processing program is to be operated after the due date.

In FIG. 2A, first, processing step 10
Asks the operating system to get the current day's date value from the system clock. In the processing step 11, the due date data held as a constant in the program is compared with the date acquired in the previous step. If the date is not larger than the due date, the processing step 12 branches to the entrance of the business processing program.

If the date is greater than the due date, the processing step
A message for the system administrator indicating that the deadline has been exceeded is output in step 13, a predetermined return code indicating a critical error is set in processing step 14, and the job is returned to the system so that this job is ended in processing step 15. The process is done and the process ends.

Also in the case of FIG. 2B, the due date is identified in the same manner as in (a) up to processing step 10 and processing step 11. As a result, if the date is not greater than the due date, the processing step
At 16 branches to the entrance of the first business processing program. or,
If the date is larger than the due date, the process branches to the entrance of the second business processing program at step 17.

FIG. 3 is a diagram showing an example of a procedure for creating a date-limited program according to the present invention. The monitoring program for the processing content shown in FIG. 2A or 2B is written in, for example, assembler language, and the monitoring program is described. Create a primitive program 20 of.

The source program 20 is input to the assembler 22 and assembled to generate the object module 23 of the monitoring program. In the source program 20, the value of the due date data is undefined and the assembler parameter 1 is set.
As an example, by inputting the due date data 21, necessary values are embedded in the program as the due date data.

It is assumed that the business processing program is normally a source program written in a high-level programming language such as the Cobol language, and is separately compiled by a compiler to generate the object module 24.

Here, the number of business processing programs is one when the monitoring program is the processing shown in FIG. 2A, and the two business processing programs are the first and second business processing when the processing is the processing shown in FIG. 2B. As a program, each object module is prepared.

By inputting the object module 23 of the above-mentioned monitoring program and one or two object modules 24 of the business processing program into the linkage editor 25 to perform the combined editing process, the load module 26 of the deadline limited program To generate.

[0023]

As is apparent from the above description, according to the present invention, when the computer program is generated, the date-limited program can be generated so that reliability can be easily maintained during maintenance. effective.
