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.

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.

A system and method that enhances the index processing performance of a multi-layer relational database manager by expanding the code generation component layer of the database manager to include an index processing performance enhancing subroutine designed to execute functions performed by lower component layers substantially faster than if the functions were executed by such lower component layers. The subroutine includes logic for establishing the conditions under which the particular subroutine is invoked during the execution of a SQL request. The output code generated to execute a specific SQL query, including calls to the index processing subroutine in place of normally included calls to the lower component layer. This enables the generated code to perform lower component layer functions with specialized code designed to increase performance.

A method for addressing mass memory in which information is stored in control intervals of physically contiguous disk segments subject to irregularities in the mapping is disclosed. Such irregularities may include discontinuities at some regular interval, which may or may not be 2', and/or offset from zero with respect to a virtual address employed by a user. Within the method, a unique hashing algorithm is employed to convert a virtual address to a physical address taking into account such irregularities in the mapping. This algorithm is particularly characterized by its use of integer binary arithmetic which results in high speed and complete accuracy. For the special and common condition in which discontinuities appearing at some regular interval of 2', a similar disclosed algorithm may be employed to achieve even greater speed of address transformation.
