Given the following declarations, which is the WORST way of setting D from 5?
DCL 1 S,
2 A(100) CHAR(1),
2 B(100) CHAR(2),
2 C(100) CHAR(3);
S = "; DCL D CHAR(600);
DCLI BIN FIXED(31);

• A. CALL PLIOVER(ADDR(D)ADDR(S),600);
• B. D = STRING(A) !! STRING(S) !! STRING(C);
• C. DO I = 1 TO 100;
  SUBSTR(D,I,1) = S.A(l);
  SUBSTR(D,1 01 + ((I-1) *2),2) = S.B(I);
  SUBSTR(D,301 + ((I-1) *3),3) = S.C(I);
  END;
• D. D = STRING(S);

Which of the following is NOT a characteristic of the RANDOM builtin function?

• A. RANDOM can be called without any parameters.
• B. RANDOM can be called with an optional SEED to avoid getting repeatable results.
• C. RANDOM can be called with an optional upper bound.
• D. The values generated by RANDOM are uniformly distributed between 0 and 1, where 0 < random() < 1.

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. 110
• B. 10
• C. 100
• D. It is unpredictable as the program will fail.

Which of the following is NOT part of the PL/I code review?

• A. Attendance of people with technical expertise
• B. Training course for the program's author
• C. Documentation of results of the review
• D. Decision whether the review object is a appropriate solution

A program reads an input file into a structure with 20 fields. Fifteen of these are required as parameters in
an external procedure. Which of the following is the most efficient way of passing these parameters?

• A. Create a structure, assign the 15 variables to it and pass the address of it in one argument.
• B. Pass the address of the input structure as one argument.
• C. Create a structure, assign the 15 variables to it and pass it as one argument.
• D. Pass 15 variables in a parameter list.
