• Question 64:

  In the following example how many lines, if any, will be printed?

  GRAPH: PROC OPTIONS(MAIN);

  DCL I FIXED BIN (31);

  DCL POINTS FIXED BIN (31);

  CALL INIT_POINTS;

  DO I = 1 TO 100;

  GET LIST(POINTS);

  CALL PLOT_NEXT(POINTS);

  END;

  INIT_POINTS: PROC;

  DCL I FIXED BIN (31);

  DCL POINTS(1000) FIXED BIN (31);

  DCL BAR CHAR (100) INIT((100)'*') STATIC;

  DO I 1 TO 10;

  POINTS(I) = I;

  PUT SKIP LIST (POINTS(I),SUBSTR(BAR,1,I));

  END;

  RETURN;

  PLOT_NEXT: ENTRY(I);

  POINTS(I) = I;

  PUT SKIP LIST(POINTS(I),SUBSTR(BAR,1 I));

  END;

  END GRAPH;

  A. 10

  B. 100

  C. 110

  D. It is unpredictable as the program will fail.

  Correct Answer: D

• Question 65:

  A file containing FIXED BINARY fields that is written by a PL/I program on Intel Architecture is to be read by PL/I programs on Intel Architecture and on the mainframe. What must be changed in the program which reads the file on Intel architecture, if anything, for it to work correctly when it runs on the mainframe?

  A. The program must declare the FIXED BINARY fields with the attribute NATIVE.

  B. The program must declare the FIXED BINARY fields with the attribute LITTLEENDIAN.

  C. The program must declare the FIXED BINARY fields with the attribute BIGEND IAN.

  D. Nothing needs to be changed.

  Correct Answer: B

• Question 66:

  Given the following code whatwill be output, if an,thing?

  DCLX FIXED DEC (5,2) INIT (-123.45);

  PUT DATA (5);

  A. S=' -123.4'

  B. S='123.45'

  C. S='-123.45';

  D. The program ends abnormally at runtime with condition CONVERSION.

  Correct Answer: A

• Question 67:

  Which of the following is a best practice to make debugging easier?

  B. Use a variable updated with the program name.

  C. CALL PLIDUMP('TFCHAB','Spot Dump'); at key points in the program logic.

  D. Use the runtime option STORAGE(00,,00,0K)

  Correct Answer: C

• Question 68:

  D. Requests are processed in parallel.

  Correct Answer: C

• Question 70:

  Which of the following may be an advantage of the BEGIN OPTIONS (INLINE) statement?

  A. The program runs faster because all variables declared inside the BEGIN block are already allocated when the block containing the BEGIN block is entered.

  B. The code runs faster because more variables will be optimized in the BEGIN block.

  C. The program uses less stack storage.

  D. The program uses less heap storage.

  Correct Answer: A
