• Question 91:

  The following structure is used when writing a file on Intel architecture which is sent to the mainframe:

  DCL 1 A,

  2 B FIXED BIN (31),

  2 C CHAR (100) VAR,

  2 D FIXED BIN (31);

  How must this structure be declared on the mainframe if the file is to be read correctly?

  A. DCL1 A,2 B FIXED BIN (31) LITTLEENDIAN,2 C CHAR (100) VAR LITTLEENDIAN,2 D CHAR (10);

  B. DCL1 A,2 B FIXED BIN (31) BIGENDIAN,2 C CHAR (100) VAR BIGENDIAN,2 D CHAR (10);

  C. D CL 1 A,2 B FIXED BIN (31) BIGENDIAN,2 C CHAR (100) VAR,2 D CHAR (10);

  D. DCL1 A,2 B FIXED BIN (31) LITTLEENDIAN,2 C CHAR (100) VAR,2 D CHAR (10);

  Correct Answer: A

• Question 92:

  Given the following example, what will happen with the PUT SKIP DATA statement after the DO- loop?

  PGM_A PROC OPTIONS(MAIN);

  DCL I FIXED SIN (31);

  DCL MON CHAR (10);

  DCL DAY(12) CHAP (2) INIT (`31',`28',`31',

  `30',`31',`30'

  31',`31',`30'

  `31',`30',`31');

  DO I = 1 TO 12;

  MON = MON_FUNC(I);

  PUT DATA (MON,DAY(I));

  END;

  PUT SKIP DATA (MON_ARR);

  MON_FUNC: PROC(INP) RETURNS(CHAP(10));

  DCL INP FIXED BIN (31);

  DCL MON_APP(12) CHAR (10) INIT (`JANUARY ',`FEBRUARY ',`MARCH `, `APRIL ',`MAY ``JUNE

  `JULY ``AUGUST ``SEPTEMBER',`OCTOBER `,`NOVEMBER `,`DECEMBER `); RETURN(MON_ARR

  (INP));

  END;

  END;

  A. A table of the months of theyearwill be printed.

  B. The compiler will issue no messages but the program will tail trying to execute the statement.

  C. The compiler will issue a message for the statement and results are unpredictable.

  D. Twelve zeroes will be printed.

  Correct Answer: C

• Question 93:

  The following program was written to copy a dataset with record length of 100 to another dataset. If this requirement has not been fulfilled, which is the most likely reason?

  DCL DDIN FILE RECORD INPUT;

  DCL DDOUT FILE RECORD OUTPUT;

  DCL INSTRUC CHAR(100);

  DCL EOF_IN BIT(1) INIT('0'B);

  ON ENDFILE(DDIN) EOF_IN = `1'B;

  DO UNTIL (EOF_IN);

  READ FILE (DDIN) INTO(INSTRUC);

  WRITE FILE(DDOUT) FROM(INSTRUC);

  END;

  A. The code fulfills the requirement.

  B. The code does not fulfill the requirement because the input structure is the same as the output structure.

  C. The code does not fulfill the requirement because the OPEN statements are missing.

  D. The code does not fulfill the requirement because too many records will be written to the output dataset.

  Correct Answer: D

  D. Which Enterprise compiler options should be specified

  Correct Answer: D

• Question 95:

  ('NO X `,0);

  IF ^PARMSET(Y) THEN NOTE('NO Y `8');

  RETURN('/* `!!X!!YI!'C */');

  %END ABC;

  A. ABC Y(B)X(A);

  B. ABC (A,);
