Which ADDI discovery output helps architects understand which COBOL programs are invoked during a nightly batch cycle?

Think of it like working hands-on with IBM mainframe systems — the answer here is the JCL job stream analysis mapping EXEC PGM statements to COBOL program invocations within job streams. It reveals batch execution topology, including job dependencies, step sequences, and shared data sets. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
