Description

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.

Topics

Language Environment - An Introduction
Introduction to Debugging and Dump Reading
Anatomy of a COBOL Compile Listing
Dump Reading — Introduction
How the COBOL compiler works
Subroutines and parameters
The Program Binder
Binder Processing
More About the Program Binder
LE Condition Handling
Dynamic CALL, CANCEL
COBOL Source Debugging Techniques

The Larger Context

By the end of this course, students will be able to:

Describe the general structure of the LE program management model
Describe the outputs of the IBM Enterprise COBOL compiler, and use these outputs correctly in
problem determination and dump debugging
Approach debugging in an orderly, efficient fashion
Locate data items from a COBOL program in an LE CEEDUMP
Better understand subroutines and parameters in a COBOL environment
Use the Program Binder to maintain load modules and program objects
Understand LE debugging facilities such as condition handling and the CEE3DMP, CEE3ABD,and CEE2AB2 LE services
Use the appropriate COBOL compiler debugging techniques to assist in tracking down and solving errors
Use appropriate Binder options and control statements, including creating a program object with a segment below the line and a segment above the line.
