Read MoreThis is the third course of a multi-part series that teaches the basics of Enterprise COBOL application development. It focuses on multi-module programs using CALL and LINKAGE SECTION, internal SORT, Variable blocked record processing, STRING, UNSTRING, INSPECT, more intrinsic functions, LE functions and XML parsing and generation.
Skills Gained
As a result of taking this course, you will be able to:
- Code main and subprograms and call subprograms from other programs, passing appropriate data
- Pass data from JCL PARMs into your main COBOL program
- Process VB records
- Code internal SORTs and use a variety of advanced SORTING techniques.
- Generate XML documents and parse XML documents (optional)
Prerequisites
Students need to have completed the Enterprise COBOL Programming: Intermediate course, and have basic experience with z/OS JCL for JES2 or JES3, and TSO/ISPF.
