Abstract

PURPOSE:To prevent the erroneous actuation of an impracticable program and the occurrence of an abnormal operation by providing a means to an execution program to confirm a practicable state of the program based on the type name of the practicable hardware or the version number of an OS contained in the program. CONSTITUTION:An execution program 1 consists of a machine word 2 and a hardware type table 3 which contains the type names of hardware that can execute the program. Thus the type name of hardware capable of execution of the program is held in the program 1, and the type name of hardware where the program 1 is loaded is read. Thus the practicable hardware is confirmed. Thus it is possible to prevent such a defective case where an impracticable hardware type name or an OS is loaded by mistake and therefore an abnormal operation is caused after execution of the program 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program loading method, and particularly to a program loading method executed by an information processing apparatus.

[Conventional technology]

Conventionally, when loading an executable program, commands and JCL
The program specified in was loaded and executed unconditionally.

[Problem to be solved by the invention]

In the conventional program loading method described above, the execution program is loaded even if the hardware model or version of the operating system (hereinafter referred to as O8) cannot be executed, so it may cause abnormal operation after execution. There was a drawback.

[Means to solve the problem]

The program loading method of the present invention includes means for retaining in an execution program the model name of the hardware on which the program can be executed, and a means for reading the model name of the hardware into which the execution program is loaded. It has a hand 1 to confirm that it is.

Furthermore, the program loading method of the present invention includes means for retaining, in an executable program, the version number of the operating system on which the program can be executed, and a means for reading the version number of the operating system into which the executable program is loaded. It has a means for confirming the version number.

〔Example〕

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

FIG. 1 shows the configuration of an execution program in an embodiment of the present invention. In Figure 1, execution program 1
consists of a machine language 2 and a hardware model name 3 having the name of a hardware model capable of executing the program.

FIG. 2 shows the format of the hardware model 3.

In FIG. 2, one entry in Table 3 consists of a hardware model name field 21 on which the program can be executed. There are entries for the number of hardware models that can execute the execution program 1.

Figure 3 shows an input method for checking whether the hardware is executable by inputting the execution program having the structure shown in Figures 1 and 2 and the hardware model name held in the hardware. It is an output diagram. In FIG. 3, this model name checking means 33 inputs a hardware model name 31 and an execution program 32, checks whether the hardware is executable according to the procedure shown in FIG. 4, and outputs a result 34.

FIG. 4 shows the confirmation procedure of the model name confirmation means 33. In FIG. 4, first, step 41 takes out the hardware model name 31 held in the hardware.
), and extracts the hardware model name 3 of the execution program 32 (step 42), then compares the hardware model name 31 and hardware model name 3 (step 43), and if they do not match, execute. The user is informed of the rejection by outputting the result (step 44).

FIG. 5 shows the configuration of an execution program in another embodiment of the present invention. In FIG. 5, an execution program 51 is composed of a machine language 52 and an O8 version number table 5°3 having the O8 version number in which the program can be executed.

FIG. 6 shows the format of the O8 version number table 53. In FIG. 6, one entry in table 53 consists of a field 61 for the number of O8 versions on which the program can be executed. There are entries for the number of O8 versions that can be executed by the execution program 51.

FIG. 7 is an input/output diagram of a means for inputting the execution program having the structure shown in FIGS. 5 and 6 and the 08O8 version number held in the O8 to check whether the O8 is executable. be. In FIG. 7, this version number confirmation means 73 is O8
Input the version number 71 and execution program 72, check whether O8 is executable according to the procedure shown in FIG. 8, and output the result 74.

FIG. 8 shows the confirmation procedure of the O8 version number confirmation means 73. In FIG. 8, first, O held in O8
8 version number 71 (step 81), and the O8 version number table 53 of the execution program 72 (step 82). Next, the O8 version number 71 and the O8 version number table 53 are compared (step 83), and if they do not match, the user is notified that execution is not possible by outputting the result (step 84).
).

〔Effect of the invention〕

As explained above, the present invention provides means for checking whether an executable program is executable based on the executable hardware model name included in the program or the version number of O8. It is possible to easily prevent an unexecutable program from erroneously running and causing an abnormal operation.
