Abstract
An interfacing computer program and system which allows a COBOL program, despite its totally different nature and internal data handling constructs and statement approaches, to effectively generate Structured Query Language (SQL) statements in accessing and using data from a SQL oriented database (8-9) and getting appropriate data back in a form consistent with what the COBOL program expects. The program's interface module (5) receives COBOL statements from an appropriately compiled COBOL program (3), and, using information contained in a data dictionary (4) created when the COBOL program (1) was compiled (note compiler 2), generates the appropriate SQL statements to access and generate the appropriate data from a SQL oriented database (8-9) for sending back to the COBOL program (3). A number of innovative programming and logic techniques are used, with innovative techniques for enhanced speed of execution.
