Generating code coverage extracted observations

Depending on the values that are provided in the Options file, z/OS® Debugger gathers observations for all statements in the programs in the Options data set. The number of observations can be large, and depends on the number of programs and the statements in the programs.

To facilitate the evaluation of the observations, z/OS Debugger Code Coverage provides a mechanism to define a subset of the observations in the final report. This is done by providing a selection mechanism that allows you to only include in the report the extracted observations for those programs that you are interested in.

You can specify how z/OS Debugger selects such programs by providing a Selection file. You can create the Selection file by using IBM® z/OS Debugger Utilities Option E.3 or by manually coding the file by following the Selection file XML DTD syntax.
