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 does not fulfill the requirement, because the READ iteration will not be left when the first
  record with '3' in the first byte appears.
• C. The code fulfills the requirement.
• D. The code does not fulfill the requirement, because not all records with '2' in the first byte will be written
  to the output dataset.

Given the following code, which condition would be raised first (if ENABLED)?
DCL A(50000) CHAR (8);
DCL I BIN FIXED (31);
DCL J BINFIXED (15);
DCI = 1 TO 100_000;
J = I;
A(J) = I;
END;

• A. SIZE
• B. FIXEDOVERFLOW
• C. CONVERSION
• D. SUBSCRIPTRANGE

A module which is serially reusable has which of the following characteristics?

• A. Must contain the necessary logic to reset control variables and data areas at entry or exit and a second
  task may not enter the module until the first task has finished
• B. Is designed for concurrent execution by multiple tasks
• C. Is intended for single use only and must be refreshed from disk before it can be invoked again
• D. All or part of it may be replaced at any time by the operating system

A file containing FIXED BINARY fields that is written by a PL/I program on Intel Architecture is to be read
by PL/I programs on Intel Architecture and on the mainframe. What must be changed in the program
which reads the file on Intel architecture, if anything, for it to work correctly when it run s on the
mainframe?

• A. The program must declare the FIXED BINARY fields with the attribute NATIVE.
• B. Nothing needs to be changed.
• C. The program must declare the FIXED BINARY fields with the attribute BIGEND IAN.
• D. The program must declare the FIXED BINARY fields with the attribute LITTLEENDIAN.

What happens after the following statements?
DCLI,J CHAR(5) INIT('54321');
I = J;
PUT LIST(l);

• A. 54321 will be printed.
• B. 5.4321E+04 will be printed.
• C. CONVERSION condition will be raised.
• D. SIZE condition will be raised.
