Which COBOL construct most often requires careful manual review after wca4z generates the equivalent Java?
Select an answer to reveal the explanation.
Short Explanation
When wca4z turns COBOL into Java, you need to scrutinize PERFORM UNTIL loops with complex exit conditions involving multiple DATA DIVISION fields. Those loops can change subtle control-flow behavior, so you verify the Java termination logic still matches the original COBOL.
Full Explanation
PERFORM UNTIL loops with complex exit conditions involving multiple DATA DIVISION fields need review because generated Java can have subtle control-flow differences, so verify termination preserves COBOL semantics. DISPLAY statements to SYSOUT, simple MOVEs, and STOP RUN are simpler and less likely to hide loop-exit issues.
