Course Description
In Part 2 of Enterprise COBOL Programming online training course, you will continue to learn the basics of Enterprise COBOL application development. The course focuses on various types of sequential I/O, and report writing as well as intrinsic functions and table processing.
In Enterprise COBOL Programming Part 1 you learned the basics of Enterprise COBOL application development as well as coding the four divisions, basic logic, data definition, and sequential I/O processing.
In This Course You Will Learn:
- Code and run COBOL programs that process raw data or stored data
- Make appropriate use of copybooks
- Create new data sets using Transaction Master Logic
- Create complex reports such as multi-level control break reports
- Code tables, indices, subscripts, intrinsic functions, and appropriate compile options
- Search tables using SEARCH, SEARCH ALL and PERFORM
Prerequisites
You will need basic experience with z/OS JCL for JES2 or JES3, and TSO/ISPF and have completed Enterprise COBOL Programming Part 1.
