What is the correct description of how wca4z generates Java code from a COBOL program?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'wca4z statically transpiles COBOL syntax to Java using deterministic grammar rules with no AI involvement'. wca4z sends COBOL source with surrounding context such as copybook definitions and service interface specifications to the fine-tuned foundation model, which returns Java source code that a developer . On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
