                          IBM Developing with IBM Enterprise PL/I FAQ: The Essentials

                          Recommended prior experience with PL/I programming and IBM mainframe environments Vendor eligibility rules do evolve, so double-check on the official page (official C9050-042 exam page) before you pay the fee.

                          Yes:

                          Official courses and our practice set complement each other: learn the theory there, then pressure-test it with the 140 practice questions for the IBM Developing with IBM Enterprise PL/I.

                          Files first: as an online product, the IBM Developing with IBM Enterprise PL/I material is obtainable immediately after ordering — an automatic email lands in your mailbox within a minute, with unlimited installations and 24/7 help if nothing shows up within 2 hours. Failure is covered too: take the corresponding C9050-042 exam within 60 days of purchase, and if you don't pass, submit a scanned enrollment slip plus the official Score Report PDF within 2 days of the exam for a full refund processed within 7 days. Exclusions apply — exams within 3 days of purchase, candidate names that don't match the payer, and free or expired products. A free exchange for two equal-value products is the alternative.

                          The IBM Developing with IBM Enterprise PL/I blueprint covers 5 domains — including File Handling and Data Management, PL/I Language Fundamentals, Debugging and Optimization. Treat the weightings as your study budget: heavy domains get heavy hours. The complete outline above lists every subtopic.

                          Correct Answer: B  🗳️

                          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 READ iteration will not be left when the first
                            record with '3' in the first byte appears.
                          • 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 program will loop infinitely.

                          • C. The values from previous invocations are preserved but can be overwritten in the new invocation.
