What format does the Explain feature in wca4z use to describe a COBOL program to a developer?

Think of it like working hands-on with IBM mainframe systems — the Explain feature gives you a natural language paragraph summarizing what the COBOL program does, its inputs, outputs, and business rules. It's meant to help a developer understand the program quickly, not to hand you a diagram or machine-readable schema. On real mainframe exams, this concept comes up repeatedly, so make sure you have it locked in.
