This paper identifies some of the factors that can affect the performance of COBOL programs when using VS COBOL II. The tuning methods discussed here are intended to assist users in selecting from the various options which are available for compiling and executing COBOL programs with VS COBOL II Release 3.2 and Release 4.0. These methods provide the COBOL programmer with the opportunity to tune the run-time environment for better CPU time performance and better use of system resources.
