Explanation

COBOL's PERFORM ... UNTIL structure executes at least once before checking the condition, which is the defining behavior of a post-test loop like do-while in Java/C++. While PERFORM ... VARYING resembles a for loop, the generic 'perform loop' term typically refers to the UNTIL variant, making do-while the best match.
