• Question 26:

  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);

• Question 27:

  Prerequisite:

  A sorted input dataset with record length 100 contains at least one record for all the values `1', `2', `3' in the first byte. The applied sort criteria is 1,100,ch,a.

  Requirements:

  1.) All records with `1' in the first byte must be ignored.

  2.) All records with `2' in the first byte must be written to the output dataset.

  3.) If there is a `3' in the first byte, the program must not read more records.

  4.) The program must not abend or loop infinitely.

  If the following code does not fulfill the requirements above, which would be the reason, if any?

  DCL DDIN FILE RECORD INPUT;

  DCL DDOUT FILE RECORD OUTPUT;

  DCL 1 INSTRUC,

  3 A CHAR(1),

  3 * CHAR(99);

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

  DCL (Z1,Z2,Z3,ZO) BIN FIXED(31) INIT(0);

  ON ENDFILE(DDIN) EOF IN = `1'B;

  READ FILE(DDIN) INTO (INSTRUC);

  IF EOF_IN THEN LEAVE;

  SELECT(INSTRUC .A);

  WHEN('1') DO;

  Z1 += Z1;

  ITERATE LAB;

  END;

  WHEN('3') DO;

  Z3 = Z3 + 1;

  LEAVE;

  END;

  WHEN('2') DO;

  Z2 = Z2 + 1;

  WRITE FILE(DDOUT) FROM(INSTRUC);

  END;

  OTHER DO;

  ZO = ZO + 1;

  PUT SKIP LIST(INSTRUC.A);

  END; END;/*SELECT*/

  END;/*LOOP*/

  A. The code does not fulfill the requirement, because the program will loop infinitely.
  B. The code fulfills the requirement.
  C. The code does not fulfill the requirement, because not all records with `2' in the first byte will be written to the output dataset.
  D. The code does not fulfill the requirement, because the READ iteration will not be left when the first record with `3' in the first byte appears.
  D. The code does not fulfill the requirement, because the READ iteration will not be left when the first record with `3' in the first byte appears.

• Question 28:

  A software package utilizes several licensed third party software components and will be sold to multiple customers who will also need runtime licenses. What information is LEAST appropriate to provide in a technical operations guide?

  C. The required release level or the third party software components
  D. The URL for the third party vendor
  B. The price or the third party software components

• Question 29:

  Y = X;

  X =Y;

  A. 3
  B. 4
  C. 5
  D. 6
  D. 6

• Question 30:

  Given the following code, what statement will produce an E level diagnostic?

  %DCL ABC ENTRY;

  %ABC: PROC (X,Y) STATEMENT;

  DCL(X,Y) CHAR;

  IF ^PARMSET(X) THEN NOTE('NO X `,0);

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

  ANSWER('/* `!lX!!Yl!'C */'); %

  END ABC;

  A. ABC(A,);
  B. ABC Y(B)X(A);
  C. ABC(,B);
  D. ABC (A,B);
  A. ABC(A,);
