A method is disclosed for translating by a computer system of a COBOL computer program into a translated computer program in a readable and maintainable syntax in an object oriented programming language. The translated program including variable names equivalent to the original COBOL variable names and with attributes described in COBOL syntax. The translating method further providing for memory allocation in the translated computer program for storage of 'COBOL' variables compatible with that of the original COBOL program; a description of program flow that is readable, and utilizing arithmetic operators to describe operations between COBOL variables. Also disclosed is a special object oriented run-time library for creating and performing operations between COBOL numeric objects, including maintaining storage of variable content in the original COBOL format, and for enabling readability of the translated source code by allowing arguments for variable type descriptions to be expressed in COBOL syntax.

Method for translating a cobol source program into readable and maintainable program code in an object oriented second programming language

A method, apparatus, and program product are disclosed for carrying out the compilation of an original Cobol program that includes a mix of Cobol, C++ or JAVA and optional OpenMP directives in a single source program file so as to provide improved performance during execution of the program and improved convenience and features in programming. The approach or method includes performing a compilation (or translation) step utilizing a first compiler or translating program which is a is a specialized compiler/translator that takes as input a Cobol source program including a further provision for the inclusion of C/C++ program statements and OpenMP statements, and produces as output an intermediate computer program, the intermediate program that is entirely in C or C++, the intermediate program being intended for further compilation by an existing selected second compiler, the second compiler being an optimizing compiler that provides support for parallelism for the programs described in the C/C++ programming languages.

Method for enabling compilation of a Cobol source program utilizing a two-stage compilation process, the Cobol source program including a mix of Cobol, C++ or JAVA statements, and optional OpenMP directives

A method and apparatus is disclosed for compilation of an original Cobol program with support for improved performance by increased parallelism during execution using multiple threads of processing. The approach includes a two stage compilation process, the first compilation/translation step by a first specialized compiler/translator that takes as input a Cobol source program that includes parallelization directives, and produces as output an intermediate computer program in a second computer programming language, the intermediate program including parallelization directives in the second computer programming language. The intermediate program is then compiled utilizing a selected second compiler that provides support for parallelism described in the second programming language. The approach optionally allows for use of pragmas serving as parallelization directives to the compiler in the original Cobol program or in the intermediate program.

Method and apparatus enabling multi threaded program execution for a Cobol program including OpenMP directives by utilizing a two-stage compilation process

A method and apparatus is disclosed for compilation of an original Cobol program and building an executable program with support for improved performance by increased parallelism during execution using multiple threads of processing. The approach includes a compilation (or translation) step utilizing a first compiler or translating program which is a parallel aware translating first compiler. The parallel aware first compiler is a specialized compiler/translator which takes as input a Cobol source program, and produces as output an intermediate computer program in a second computer programming language, the intermediate program including parallelization directives, the intermediate program intended for further compilation utilizing an existing selected second compiler, the second compiler providing support for parallelism for programs described in the second programming language. The approach optionally allows for use of pragmas serving as parallelization directives to the compiler in the original Cobol program or in the intermediate program.
