Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a program execution method according to an embodiment of the present invention. The main parts of the program execution method of this embodiment include a program 1 and a task control mechanism 5 of the current operating system.

The program 1 includes a plurality of tasks 2 and a macro parameter analysis/conversion means 4 in advance of the task control macros provided by the task control mechanism of the original operating system used by the tasks 2 in the program 1.
Called from the task control macro modified by the macro modification means 3 and the task control macro of the original operating system?
macro/parameter analysis/conversion means 4 that analyzes task control macros and parameters provided by ffU JIA Yokota and attempts to convert them into task control macros provided by the task control mechanism 5 of the current operating system; In the process of converting the task control macros and parameters by the parameter analysis/conversion means 4, it is determined that the functions of the task control macros and parameters are equivalent to or include the functions of the task control macros and parameters provided by the task control mechanism 5 of the current operating system. If it is determined that the macro/parameter analysis/conversion means 4 will execute the corresponding task control macro provided by the task control mechanism 5 of the current operating system, the macro/parameter analysis/conversion unit 4 directly executes the corresponding task control macro provided by the task control mechanism 5 of the current operating system and sends a return code indicating the execution result to the macro/parameter analysis/conversion means 4. The corresponding macro direct execution means 6 returns to the parameter analysis/conversion means 4, and in the process of converting the task control macros and parameters in the macro/parameter analysis/conversion means 4, the functions of the task control macros and parameters are updated to the task control of the current operating system. A task provided by the task control mechanism 5 of the current operating system that is called by the macro/parameter analysis/conversion means 4 when it is determined that the functions of the task control macro and parameters provided by the mechanism 5 do not correspond.

．． It is configured to include an initialization means 8 for initializing various tables M (not shown) used by the corresponding macro direct execution means 6 and the corresponding macro simulation means 7.

Next, the operation of the program execution method of this embodiment configured as described above will be explained.

When execution of the program 1 is instructed, the macro modification means 3 is first activated.

Prior to the start of execution of the program 1, the macro modification means 3 analyzes and converts all the task control macros provided by the task control mechanism of the original operating system used in the task 2 in the program 1. Modify to call means 4.

Further, at the same time as the macro modification means 3 is activated, the initialization means 8
is also started.

Prior to starting execution of the program 1, the initialization means 8 performs the following steps.
The macro/parameter analysis/conversion means 4 initializes various tables used by the corresponding macro direct execution means 6 and the corresponding macro simulation means 7, and then passes control to the original entry of the program 1 to execute the program 1.
starts execution.

When execution of the program 1 is started and the task control macro modified by the macro modification means 3 included in the task 2 is executed, the macro parameter analysis/conversion means 4 executes the task control macro modified by the macro modification means 3. The task control macros and parameters initially provided by the task control mechanism of the operating system are called from the control macros corresponding to each task control macro, and the task control macros and parameters initially provided by the task control mechanism of the operating system are analyzed to determine the task control macros provided by the task control mechanism 5 of the current operating system. and attempt a one-to-one correspondence with parameters. Here, if the task control macro and parameter can be associated one-to-one at the functional level, the macro/parameter analysis/conversion means 4 calls the corresponding macro direct execution means 6.

The corresponding macro direct execution means 6 called by the macro/parameter analysis/conversion means 4 requests the task control mechanism 5 of the current operating system to execute the specified task control macro, causes it to be executed as is, and executes the specified task control macro. If there is a return code from the task control mechanism 5, this return code is returned to the macro/parameter analysis/conversion means 4 as an execution result.

The macro/parameter analysis/conversion unit 4 that receives the return code from the corresponding macro direct execution unit 6 converts the returned return code into the return code of the task control macro originally provided by the task control mechanism of the operating system. , returns control to task 2, which is the issuer of the task control macro.

On the other hand, if the macro/parameter analysis/conversion means 4 determines that there is no correspondence between the task control macro and parameters and the task control macro and parameters provided by the task control mechanism 5 of the current operating system, the macro - The parameter analysis/conversion means 4 calls the corresponding macro simulation means 7.

The corresponding macro simulating means 7 called by the macro parameter analysis/conversion means 4 uses the task control macro provided by the task control mechanism 5 of the current operating system, and uses the task control macro provided by the task control mechanism of the current operating system. Simulates the task control macro being used. As a result of the simulation, if there is a return code from the task control mechanism 5 of the current operating system, this return code is returned to the macro parameter analysis/conversion means 4 as an execution result.

The macro/parameter analysis/conversion unit 4 that receives the return code from the corresponding macro simulator 7 converts the returned return code into the return code of the task control macro originally provided by the task control mechanism of the operating system. , returns control to task 2, which is the issuer of the task control macro.

In the above embodiment, the macro modification means 3 is incorporated into the program 1 so that the task control macro in the task 2 is modified immediately before the start of execution of the program 1 when the program 1 is an object program. , by incorporating macro modification means 3 into the compiler and recompiling program 1 using the compiler's macro file search rules to give top priority to searching for the macro file that stores the task control macro that you want to enable. , the task control macro may be modified.
