Overview

Audio

This course describes how to use the ILE source-level debugger to debug a program interactively. It shows how to set breakpoints (both unconditional and conditional), display the value of a data item, change the value of a data item, and step through a program one statement at a time. It covers all of the debugging functions provided by the debugger, both those implemented using debugging commands and those implemented using function keys.

Approximate Study Time: 2 hours

Objectives

After completing this course, you should be able to:

  • Define and use the terms related to the ILE source-level debugger, such as debug mode, debug data, and debug view
  • Name and describe the different debug views that can be generated when creating a module
  • Start the ILE source-level debugger by placing your interactive job in debug mode
  • Set both unconditional and conditional breakpoints in a program
  • Display the current contents of a data item
  • Change the contents of a data item
  • Step through a program one statement at a time
  • Use a watch condition to stop program execution when the value of a data item is changed
  • Add programs to and remove programs from debug mode
  • Define and use abbreviations for a data item name, an expression, or a debug command while debugging a program
