<p>The system communicates the results of I/O operations to the program using <span class="keyword">i5/OS™</span> messages
|
||
|
|
and I/O feedback information. The system updates the I/O feedback area for
|
||
|
|
every I/O operation unless your program uses a blocked record I/O. In that
|
||
|
|
case, the system updates the feedback area only when you read or write a block
|
||
|
|
of records. Some of the information reflects the last record in the block.
|
||
|
|
Other information, such as the count of I/O operations, reflects the number
|
||
|
|
of operations on blocks of records and not the number of records. See your
|
||
|
|
high-level language manual to determine if your program uses blocked record
|
||
|
|
I/O.</p>
|
||
|
|
<p>The I/O feedback area consists of two parts: Common I/O Feedback Area
|
||
|
|
and a file-dependent area. The file-dependent area varies by the file type.</p>
