Debugging PL/I Projects

Enterprise Developer provides an environment for debugging PL/I projects, which includes all the usual features such as stepping, watch windows and breakpoints.

When you debug an application, the source code of each program is displayed in a separate window. Each line of the source is highlighted in turn as each statement is executed, showing the effect of each statement. You can execute the program at full speed and can interrupt execution to examine and change data items.

The features available while debugging include:

• Running all or part of the program, and stepping through the program one statement at a time
• Executing the program until it reaches a specified point, such as the end of a procedure or a breakpoint that you specify
• Skipping statements you do not want to execute, such as a procedure call and the corresponding procedure.
• Examining and manipulating data items while debugging

There are a number of ways to debug code, such as compiling the source yourself first or letting it happen automatically or making available the necessary files created during an earlier compilation. For example you can:

• Automatically start debugging when the application fails
• Debug services and applications that are running on a local or a remote enterprise server

You control the way debugging works by setting options on the Debug page of the project's properties and in the option pages which you can access from Debug > Options and Settings > Debugging.

Here you can access a number of debug features such as creating a debug profile, launching a debug wait for debuggable attachment process, specifying application arguments, and setting environment variables using key/value pairs.
