36 Chapter 36. Scenario 2: using Debug Tool In this chapter we describe the application components that exist in the batch environment on our system and show how they are set up. We explain the processing that is performed in the batch Trader application. The application is forced to produce incorrect output, and then we describe the steps required to identify the logic error in the application using Debug Tool in batch mode. We also define how to step through the program to isolate and correct the problem using Debug Tool in foreground mode.
