This course provides application developers with more complex knowledge in developing COBOL programs in a mainframe environment. Time is spent in more difficult programming workshops using both VSAM and sequential file processing, 2 dimensional arrays, internal sorting, COBOL sub programs, intrinsic functions, and processing both UNIX files and Unicode data. Much of the time is spent on hands on workshops writing and testing programs.
Application programmers who want to learn more COBOL.
Upon successful completion of this course, the student will be able to:
- Understand the principles and practices of working with sequential and VSAM files
- Be able to code COBOL programs which utilize files
- Be able to code COBOL programs with 1 and 2 dimensional arrays
- Understand and code COBOL programs using SORT/MERGE
- Understand how to work with COBOL called programs
- Understand how to work with COBOL variable length files
- Understand VSAM primary and alternate key processing
- Better understand more in depth testing and debugging
- Know how to code many of COBOL’s intrinsic functions
Students MUST be familiar with z/OS JCL, TSO/ISPF and z/OS Utilities and a programming background is preferred. Students MUST have taken CO1010 course, Introduction to COBOL Programming or have comparable experience.
