2. Variable A has a syntax error and the code as provided will not compile.

4. Your answer is wrong -- GOBACK and STOP RUN are equivalent statements in a standalone program.

5. NONE of the answers are right. X'02431C' is the right answer. If the number was unsigned, X'02431F' would be correct -- but the C in the sign means +, whereas F means unsigned (default positive).

7. The definition is right -- so your answer is wrong. B is the answer they're looking for, since T1 will not be variable length if it is in WORKING-STORAGE.

12. Answer C is correct.

13. Answer A is correct.

15. Answer A is correct.

17. None of the answers is correct.

19. Syntax error in UNTIL W-NUM ] 9 If this is supposed to be > 9, then W-NUM, as a single byte variable, cannot ever, under any circumstances, have a value larger than 9.

22. What was the initial value of NO-OF-REC?

23. Answer A is correct -- V in a PICTURE is implied decimal point and never appears in the data.

25. Answer D is correct.

b) 09
c) 11
d) infinite loop.


(19) Consider the following:
