IBM Developing with IBM Enterprise PL/I: Common Questions From Candidates

What is the IBM Developing with IBM Enterprise PL/I certification exam?

The IBM Developing with IBM Enterprise PL/I exam (code: C9050-042) is the official IBM exam that leads to the IBM Certified Application Developer certification. It sits at the Professional level of the IBM certification track. Passing it proves to employers that your skills have been validated by IBM itself, which is why the C9050-042 credential keeps showing up in job postings.

How many questions are in the C9050-042 exam, and how long does it take?

The IBM Developing with IBM Enterprise PL/I exam gives you 90-120 to work through 60-140. Pacing matters more than most candidates expect, so before exam day, run at least one full timed session in the Dumpkiller test engine to learn how long you can afford per question. If an item stalls you, flag it and move on — coming back later beats burning five minutes on a single question.

What score do I need to pass the C9050-042 exam, and how much does it cost?

The passing score for the IBM Developing with IBM Enterprise PL/I exam is 70%, and the official registration fee is USD 200-300. Remember that a failed attempt means paying that fee in full again, so a timed self-assessment with Dumpkiller practice questions about a week before your exam date is a cheap way to confirm you are scoring comfortably above 70%.

IBM Developing with IBM Enterprise PL/I Sample Questions:

Question 1

A dummy argument is NOT created when a routine is called in which of the following situations?

A. With a constant as parameter
B. Where the attributes(s) of the arguments and parameters are the same
C. With the attributes(s) of the arguments and parameters are not the same
D. Using SUBSTR as one of the arguments

Question 2

What happens after executing the following code?
DCL OUTFILE FILE RECORD OUTPUT;
DCLP PTR;
DCL I BIN FIXED(31);
DCL A BIN FIXED(31) BASED(P);
DO I = 1 TO 10;
LOCATE A FILE(OUTFILE) SET(P);
A = I;
END;
CLOSE FILE(OUTFILE);

A. 10 records will be written with first record value undefined.
B. 9 records will be written with value 1 to 9.
C. 9 records will be written with value 2 to 10.
D. 10 records will be written with value 1 to 10.

Question 3

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 the input structure is the same as the output
structure.
B. The code does not fulfill the requirement because too many records will be written to the output
dataset.
C. The code fulfills the requirement.
D. The code does not fulfill the requirement because the OPEN statements are missing.

Question 4

Given the following pseudocode example, at which label should an unconditional COMMIT be placed
assuming there is a one-to-many relationship between FIL01 and FIL02 and FlL01 contains several
thousand records?
Read record from file FIL01
1 . DO while there are records in FIL01 IF record in FIL01 specifies update THEN DO for all records
matching in FIL02 Update record in FIL02 with information from FIL01 end DO
2 . end IF
3 . Read next record in FIL01
4 . end DO

A. 1
B. 2
C. 3
D. 4

Question 5

What will be printed, if anything, to SYSPRINT after the following statements are executed?
CALL REVERSEIT('PL/I');
(SUBSCRIPTRANGE,SIZE,STRINGSIZE):
REVERSEIT:PROC(31);
DCL(I,J) BIN FIXED(31);
DCL (S,T) CHAR(100) VARYING;
T = S;
J = 0;
I = 0;
DO I = LENGTH(S) TO 1;
J = J + 1;
SUBSTR(T,J,1) = SUBSTR(S,I,1);
END;
PUT(T);
END;

A. 'I/LP'
B. SUBSCRIPTRANGE error will be raised.
C. 'PL'I'
D. STRINGSIZE error will be raised.
