Question 3

Which of the following structures will NOT contain padding btes if the PL/I default for alignment is applied?

A. DCL 1 A ALIGNED,
2 B FIXED BIN(31),
2 C CHAR (2) VAR,
2 D FIXED BIN(31),
2 E FIXED DEC (1),
2 F CHAR (3) VAR,
B. DCL 1 A,
2 B FIXED BIN(31),
2 C CHAR (2) VAR,
2 D FIXED BIN(31),
2 E FIXED DEC (1),
2 F FLOAT DEC (6);
C. DCL 1 A,
2 B FIXED BIN(31),
2 C CHAR (2) VAP,
2 D FIXED BIN(31),
2 E FIXED DEC (1),
2 F CHAR (3) VAR ALIGNED;
D. DCL 1 A,
2 B FIXED BIN(31),
2 C CHAR (2) VAR ALIGNED,
2 D FIXED BIN(31),
2 E FIXED DEC (1),
2 F CHAR (3) YAP;

Question 4

What are the requirements on data to apply parallelization in a program?

A. It should follow the Relational model.
B. It should follow the Object model.
C. It should be partition able.
D. It should follow the Hierarchical model.

Question 5

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