Enterprise COBOL Debugging and Maintenance

Course Number:  648-TF
Recommended Duration:  2 days

Intended Audience
COBOL programmers who need to know how to code calling and called programs (subroutines) and who need to know how to debug these programs in the LE environment; programmers who need to know how to use the Program Binder for maintenance.

Objectives
The student learns how to use the Language Environment (LE) and COBOL facilities for debugging as well as how to effectively do maintenance on a module that has been debugged.  The Program Binder is also discussed extensively.  There are three hands-on exercises.

Prerequisites
Basic understanding of the COBOL language, and a working knowledge of how to code JCL statements.  Fundamental understanding of CALL statements and basic subroutine concepts.
