Abstract

A program processing system for processing a program including a first program division written in a first programming language and a second program division written in a second programming language comprises an operating system 100, a program processor 200 for compiling the first and second program divisions to produce first and second modules, and registering the second module by using an identifier assigned by the operating system when the first module is registered, and a program executor 300 for retrieving the second module by using the identifier assigned to the first module and executing the second module while executing the first module. This obviates generation of unnecessary identifiers and simplifies system configuration.

means for compiling the program to produce from said first program division and said second program division a first module and a second module, the first module having an identifier assigned by the operating system, and

means for registering the second module by using the identifier assigned by the operating system to the first module.

3. A system for executing first and second program modules obtained from a program having a first program division written in a first programming language and a second program division written in a second programming language, the first module having an identifier assigned by an operating system which executes said first module, the second module being assigned an identifier which is dependent upon the identifier of the first module, the system including:

means for executing said first module;

means for retrieving the registered second module by using the identifier assigned to said second module, and

means for executing said second module.

4. A system for compiling a source program including a first program division written in a first programming language and a second program division written in a second programming language, comprising:

means for compiling said second program division to produce a second module,

means for providing said first program division with reference information for referencing said second module by using a part of the identifier assigned to a first module obtained by compiling the first program division;

means for compiling said first program division to produce the first module, and for obtaining the identifier to the first module from an operating system;

means for registering said second module so that said second module can be referenced by using the identifier assigned to said first module.

5. A system for compiling and executing a program including a first program division written in a first programming language and a second program division written in a second programming language, comprising:

means for compiling said first program division to produce a module,

means for holding said second program division in the module; and

means for executing said module, and

means for converting said second program division into an executable format while executing said module.

6. A system for compiling a program including a first program division written in a first programming language and a second program division written in a second programming language, comprising:

means for compiling the second program division to create a program module,

means for editing the program so as to replace the second program division with a unique identifier to the program module,

means for appending the program with a third program division written in the first programming language and designated in the first programming language as a constant and representative of the second program division, and

means for compiling said edited and appended program to produce an executable module.

7. A system for compiling a program including a first program division written in a first programming language and a second program division written in a second programming language, comprising:

means for appending the program with a third program division written in the first programming language and designated in the first programming language as a constant and representative of the second program division; and

means for compiling said first and third program divisions, as a program division in the first programming language, to produce an executable module.

8. A system for compiling a program including a first program division written in a first programming language and a second program division written in a second programming language, comprising:

means for compiling the second program division to obtain a program module;

means for replacing the second program division in the program with reference information written in the first programming language and having a first identifier relative to the program;

means for compiling the program in the first programming language to obtain a load module to which a second identifier is assigned by an operating system;

means for registering the program module by using a third identifier comprising the first and second identifiers.

9. A method for compiling and executing a program including a first program division written in a first programming language and a second program division written in a second programming language, comprising the steps of:

compiling the program to produce from said first program division and said second program division of said program a first module and a second module,

obtaining an identifier assigned to the first module by an operating system,

registering the second module by using the identifier assigned to the first module; and

executing said first module,

retrieving the registered second module by using the identifier assigned to said first module while executing said first module, and

executing said second module.

10. The method of claim 9, wherein the identifier assigned to the first module by the operating system is an identifier used by the operating system during execution of the first module.

11. The method of claim 9, wherein the identifier assigned to the second module includes a procedure name which is executed to obtain the identifier used by the operating system during execution of the first module.

12. The method of claim 9, wherein the second module is stored in an intermediate file during compilation, and wherein the second module is registered after compilation of the program.

13. A method for compiling a computer program having a first program division written in a first programming language and a second program division written in a second programming language, comprising the steps of:

compiling the program to produce from said first program division and said second program division of said program a first module and a second module,
