IBM Developing with IBM Enterprise PL/I Sample Questions:

Question #1
Given the following code example, what is the value of A after the last CALL to ADD_RUT?
PGM2: PROC OPTIONS(MAIN,REENTRANT) REORDER;
DCL A BIN FIXED (15);
A =1
CALL ADD_RUT(A);
CALL ADD_RUT(A);
CALL ADD_RUT(A);
ADD_RUT:PROC (VAL);
DCL VAL DEC FIXED (15);
VAL = VAL + 1;
END ADD_RUT;
END PGM2;

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

Question #2
Given the following statements, where will the variables A, B and C be allocated?
DCL A FIXED;
DCL B CHAR(80) BASED(P);
DCL C CHAR(1000) CONTROLLED;
DCL D AREA(1000);
DCL P PTR STATIC;
ALLOC C;
ALLOC B IN(D);

A. A in STACK, B and C are in HEAP
B. A and B are in STACK, C in HEAP
C. A in STACK, B in STATIC, C in HEAP
D. A in HEAP, Band C are in STACK

Question #3
Which of the following compile list sections would be used to find the location of a static variable in a
dump?

A. Source Listing
B. Storage Offset Listing
C. Table of Offsets and Statement Numbers
D. Attribute/Xref Table

Question #4
Requirement Copy a dataset of record length 100 to another dataset.
If the following code does not fulfill the requirement above, 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;
READ FILE(DDIN) INTO(INSTRUC);
DO WHlLE(^EOF_IN);
WRITE FILE(DDOUT) FROM(INSTRUC);
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 fulfills the requirement.
C. The code does not fulfill the requirement because too many records will be written to the output dataset,
except when the input dataset is empty.
D. The code does not fulfill the requirement because the OPEN statements are missing.
