Abstract

PURPOSE:To control the operation of an execution program under execution presently by providing a control file to be referred by the executing program during the execution and providing a means to change data in the control file by the other program. CONSTITUTION:An execution program 21 is internally equipped with an analysis control part 23 to analyze a control file 4, to give an instruction to the operation of the whole executing program 21 and to control the operation. A preparation and edition program 22 is a program for newly preparing the control file 4 based on the data inputted from an input/output device or to re-edit the data of the control file 4 already prepared. The execution program 21 under the execution is controlled through the data in the control file 4. Thus, the operation of the execution program 21 presently under the execution is controlled and without making a processed result up to the moment useless, the operation of the executing program 21 can be finished or processing, which is different from processing intended at first, can be executed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a program control method, and in particular, the present invention relates to a program control method, and in particular, changing the data in a control file by another program while an execution program is being executed. Concerning program control methods for controlling operations. [Prior Art] In the conventional program control method, processing is performed using various data set before execution according to instructions programmed before execution. Therefore, as a matter of course, if the same data is input to the same program, the same processing result will be obtained after the same processing time is spent, and in this case, The content of the operation cannot be changed during operation [Problem to be solved by the invention] In the conventional program control method described above, both the program and data must be determined and input before execution. ,
The operation details could not be changed during operation, so
Once execution has started, if for some reason you want to perform another operation or end the operation, the only way to deal with it is to run the program to the end, or
There is a problem in that there is no way to deal with the problem other than forcibly terminating it at the risk of destroying the executed program and input data. In addition, in the case of forced termination, even if the program and data are not destroyed, the processing results up to the middle of the processing by the computer will be destroyed regardless of whether they are valid or invalid, so the amount of time spent on this processing will be destroyed. The problem is that time and computer usage costs are wasted.

An object of the present invention is to provide a control file for reference by an executable program during execution, and to provide means for changing data in this control file by another program, thereby controlling the operation of the currently executing program. control,
The object of this invention is to provide a program control method that makes it possible to terminate the operation of an executable program without wasting the results of previous processing, or to execute processing other than what was originally intended. [Means for Solving the Problems] The program control system of the present invention has an input/output device that inputs and outputs data and commands, a data storage device that can store and read data, and a plurality of programs in parallel. an operating system to be executed and an arithmetic processing function that connects the input/output device or the data storage device to perform arithmetic processing on the input data; and an output function that outputs the results of the arithmetic processing to the human output device and the data storage device. In a program control system for a computer comprising an execution program having a built-in arithmetic processing unit, a control file defining detailed control procedures for executing the execution program; an analysis control section included in the execution program that has a function of successively analyzing the contents of the control file and using it for control; and a creation/editing program that has a function of performing computation and processing editing in parallel independent of the above control file, and is configured to control the running execution program via the data in the control file. be. [Example] Next, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention. The input/output device Wl is connected to the arithmetic processing device W2, and inputs data necessary for control and outputs results. The processing unit W2 is
An execution program 21 performs necessary processing on data input from the input/output device 1 and writes and reads data to and from the data storage device 3 and control file 4; It includes a discipline editing program 2-2 which has the function of performing calculations, processing and editing, and creating a control file 4. The control file 4 is edited by the creation or editing program 22 and read out by the execution program 21.

Figure 2 is a block diagram showing the relationship between the execution program, creation/editing program, and control file. The execution program 21 includes an analysis control section 23 that analyzes the control file 4 and gives instructions to and controls the overall operation of the execution program 21.
Contains. The creation/editing program 22 is a program for creating a new control file 4 or editing the data of the control file 4 that has already been created based on data input from the input/output device 1.

FIG. 3 is a flowchart of one embodiment of the present invention.

Next, the operation will be explained mainly using FIG. 3.

When the execution program 21 starts running, the internal variable: time is first set to "O" in step (hereinafter referred to as S) 31.
Set. Next, in S32, "8 methods" is set for the internal variable: method. Next, the operation is once transferred to the analysis control unit 23, and in step 333, "edit time of control file 4" is set in the internal variable: fjime. This editing time is the time required for editing added to the control file 4 when the control file 4 is edited using the creation/editing program 22. Next, in step 334, internal variables: time and ftime are compared, and if ftime is larger, control file 4 is read out in step S35, instruction data is received, and internal variable: method is set to "method specified by control file". do.

Next, in 336, set the internal variable: tinge to “edit time ft
Set ime J and move on to the next 337. In S34, internal variables: time and ftin+e are compared, and ftim
If e is not larger, the process moves directly to S37. S37
Then, identify the ``method set'' for the two internal variable methods and execute the specified ``method''. For example, if "method A" is specified, method A is executed in S38-1.

Next, unless normal termination processing is specified in 339, the process returns to 333 and repeats the same steps. Also, if "end processing" is specified in S37, S38-
At step 3, the termination process is executed, and the operation of the execution program 2l ends.

〔Effect of the invention〕

As explained above, the present invention provides a control file for reference by an execution program during execution, and provides a means for changing data in this control file by another program. This has the effect of controlling the operation of the program, allowing the execution of the program to end without wasting the results of the previous processing, or executing a process different from what was originally intended.
