Abstract

PURPOSE:To prevent the malfunction of an electronic computer system from occurring by eliminating the simultaneous start-up of plural programs for which the simultaneous start-up are prohibited by providing a program nonsimultaneous operation managing means and a program execution state managing means. CONSTITUTION:The program nonsimultaneous operation managing means 1 is composed of a memory element or a magnetic file, and stores the combination data of the program to prohibit a simultaneous operation. The program execution state managing means 2 is also composed of the memory element or the magnetic file, and stores data representing an execution state at every program unit, and data representing the program to be executed just before, and data representing the execution state of the program to be executed just before. Thereby, it is possible to automatically perform the control of the nonsimultaneous operation of the program being operated on an electronic computer system and the control of execution sequence, which reduces a load on system management and evades the malfunction of the system.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program execution control method in a general-purpose terminal system, and more particularly to a program execution control method in a general-purpose terminal system in which a plurality of programs can run simultaneously.

[Conventional technology]

Conventionally, programs in electronic computer systems having multiprogramming functions are executed based on instructions from an operator. At this time, in the above-mentioned system, the combination of programs that must not be started at the same time and the management of programs that must follow a certain execution order are left to the operator.

[Problem to be solved by the invention]

In the conventional program execution control method in the general-purpose terminal system described above, when there are multiple operators, multiple programs that should not be started at the same time are started simultaneously, causing the computer system to malfunction. There was a problem.

[Means to solve the problem]

The program execution control method in the general-purpose terminal system of the present invention includes a program non-simultaneous operation management means for managing combinations of other programs that must not be operated simultaneously for each program unit, and a program execution control means for managing the execution state of the program unit. a program execution state management means; a program start request management means for managing a start request for the program; a program stop request management means for managing a stop request for the program; and a startability management means for managing whether the program can be started. It is configured with.

〔Example〕

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

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

The program execution control method in the general-purpose terminal system shown in Fig. 1 includes a program non-simultaneous operation management means 1 that manages combinations of other programs that must not run simultaneously for each program unit, and a program execution control means 1 that manages the execution state of each program unit. program execution state management means 2 for managing program activation requests; program activation request management means 3 for managing program activation requests;
It is comprised of a program stop request management means 4 for managing program stop requests, and a startability management means 5 for managing whether a program can be started.

Next, the operation will be explained.

In FIG. 1, the program non-simultaneous operation management means 1 includes:
The non-simultaneous program operation management means 1, which is composed of a memory element or a magnetic file, stores combination data of programs that prohibit simultaneous operation. The program execution state management means 2 is also constituted by a memory element or a magnetic file, and the program execution state management means 2 contains data indicating the execution state for each program acceptance, data indicating the program to be executed immediately before, Data indicating the execution state of the program to be executed immediately before is stored.

Further, the program startup request management means 3 receives a startup request from a program or an operating system, and
The data indicating the execution status of the corresponding program stored in the zero-gram execution status management means 2 is replaced with the data "currently running" indicating that the program is being executed.

In addition, the program stop request management means 4 receives a stop request from a program or the operating system, and converts the data indicating the execution state of the corresponding program in the program execution state management means 3 to "", which indicates that the program is being stopped. Replace with the data of the stopped program.

-Furthermore, the activation permission management means 5 receives a activation request from a program or an operating system, and determines whether the program satisfies the execution conditions based on each data of the program non-simultaneous operation management means 1 and the program execution state management means 2. Determine whether or not there is. If the conditions are met,
"Executable" data is notified to the program or operating system as a parameter, and if the conditions are not met, "unexecutable" data is notified to the program or operating system. Based on this parameter, the program Alternatively, the operating system can control program startup.

FIG. 2 is a flowchart showing the processing of the program execution control method in the general-purpose terminal system of FIG.

FIG. 2 shows a processing procedure for determining whether the above-mentioned program or a program requesting startup from the operating system can be started.

First, the data indicating the execution state of the corresponding program stored in the program execution state management means 2 is replaced with the data of the program currently being executed (step 20). Check the data indicating the execution state of the non-simultaneous operation program defined in the means 1, and if all the data indicating the execution state of the non-simultaneous operation program in the program execution state management means 2 are stopped, step 22 If all the data indicating the execution status of the non-simultaneously operating programs in the program execution status management means 2 are "currently running" data, the process advances to step 28 (step 21).

Furthermore, it is determined whether or not the immediately preceding program is defined based on the data indicating the immediately preceding program of the activation request program stored in the program execution state management means 2. If the immediately preceding program is undefined, the process proceeds to step 24. , if defined, the process advances to step 23 (step 22). In step 23, if the data indicating the preceding program status is "completed", the process advances to step 24, and if it is "not executed", the process advances to step 28.

In step 24, the program or operating system is notified of data indicating that the program can be started. When data indicating that "program can be started" is notified, the program is started (step 25). When the program stops in response to a program stop request from the program or the operating system, in step 26), data indicating the execution state of the program execution state management means 2 of the corresponding program is replaced with data indicating "stopped", The data indicating the execution state of the preceding program is replaced with "execution completed" or "not executed" (step 27).

In step 28, the program or the operating system is notified of data indicating that "program cannot be started," so that the program cannot be started. Replace the “running” data replaced in step 20 with “stopped” data (2 steps)
.

〔Effect of the invention〕

As described above, the present invention reduces the burden of computer system management on the operator by automatically controlling non-simultaneous operations of programs running on a computer system and controlling the execution order. This has the effect that malfunctions of the system can be avoided.
