Enterprise COBOL Debugging & Maintenance

2 Days

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
  • LE Debugging Services
  • LE: The Run-Time Environment
  • Guidelines for Debugging - recap
  • 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.
