Advanced COBOL Application Programming

This course begins with a review of single dimensional array processing techniques before beginning multidimensional array processing techniques. File processing techniques including sorts, merges, and transaction processing will be covered. Structured Programming techniques and modularization including both internal and external subroutines will be taught and used in all programming projects. Database processing will be taught using both VSAM, including IDCAMS, and DB2. DB2 will be taught using both interactive processing with SQL Processor Using File input (SPUFI) and batch processing using embedded SQL. This course uses weekly programming projects to enable the student to practice what is being taught. These programming projects will be entered, compiled and executed on the Marist College z/OS mainframe computer using TSO.
