IBM C9050-042 Exam Syllabus Topics:

IBM Developing with IBM Enterprise PL/I Sample Questions:

1. 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.

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

A) 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;
B) 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;
C) 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);
D) 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,

3. A given PL/I program has a big nesting depth. Which of the following measures will help to reduce the
nesting depth in most cases?

A) Avoiding OTHER clauses
B) Avoiding ELSE clauses
C) Using SELECT constructs instead of If-THEN-ELSE

4. What characterizes the relational model with respect to data storage?

A) Data is stored in hierarchies.
B) Data is stored in segments.
C) Data is stored in variable length and format.
D) Data is stored in tables.

5. A mainframe project is behind schedule and a project leader has only one copy of a PC-based PL/I
compiler available for distribution to team members who are all eager to use it. Optimally, to whom should
it be provided first?

A) The project leader and her manager
B) The person in the critical path
