When the first wca4z code generation attempt produces Java that does not fully match the COBOL logic, what is the recommended next step?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'Abandon wca4z and manually rewrite the COBOL program in Java from scratch'. wca4z supports an iterative workflow where developers refine the context, add copybook definitions, or adjust model prompts to produce progressively better Java output before accepting the final resul. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
