Abstract:
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.

Abstract:
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.
