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.
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.
