QUESTION: 134
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 too many records will be written to
the output dataset, except when the input dataset is empty.
B. The code does not fulfill the requirement because the input structure is the same as the
output structure.
C. The code does not fulfill the requirement because the OPEN statements are missing.
D. The code fulfills the requirement.
