Summary
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.
Prerequisites
Before taking this course, students should have a basic understanding of the COBOL language, and a working knowledge of how to code JCL statements. Students should also have a fundamental understanding of CALL statements and basic subroutine concepts.
Duration
2 Days/Lecture & Lab
Audience
This course is designed for 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 will also find this course beneficial.
