Students will be introduced to Virtual Storage Access Method (VSAM). The structure and application of Virtual Storage Access Method (VSAM) datasets, i.e., ESDS, KSDS, and RRDS, are compared. Using the IDCAMS utility students will create and a manage VSAM clusters to support basic file maintenance applications. Other COBOL topics include advanced table processing; batch ESDS, KSDS, and RRDS processing and updating, and the use of sub-programs. Additional concepts covered are structured program design considerations, the interrelationship of programs within an information system, coding for program efficiency and clarity, and the creation and use of quality program documentation.
