fields.</p>

|
||
<dd>Header Label (the beginning of a data set)</dd>
|

<dt class="dlterm">EOV</dt>

<dd>Trailer Label (the end of a data set that is continued on another volume)</dd>
|
||
</dl>
|
||
</div>
|
||
</li>
|
||
<li>Label number <p>The relative position of this label within the set of
|
||
labels of the same type; it is always 1 for the data set label 1.</p>
|
||
</li>
|
||
<li>File Identifier <p>A unique identification code to identify the data
|
||
set (file). If the data set ID is less than 17 characters, it is left justified
|
||
and padded with blanks.</p>
|
||
</li>
|
||
<li>File Set Identifier <p>This field contains the volume identifier from
|
||
the volume labels of the first volume in a multivolume data set.</p>
|
||
</li>
|
||
<li>File Section Number <p>This field contains the relative volume number
|
||
of this volume in a multivolume data set. The field is 0001 for a single volume
|
||
data set.</p>
|
||
</li>
|
||
<li>File Sequence Number <p>This field indicates the relative position of
|
||
the data set within a multiple data set group. The value will be in EBCDIC
|
||
displayable characters for 0001–9999. For numbers larger than 9999 that will
|
||
not fit in the 4–character field as an EBCDIC displayable character set, the
|
||
first byte will a '?' ('6F'x for EBCDIC labels. The last three bytes will
|
||
be a binary number from 1 to 64000.</p>
|
||
</li>
|
||
<li>Generation Number (not used) <p>If the data set is a part of a generation
|
||
data group, this field contains a number that indicates an absolute generation
|
||
number. <span class="keyword">i5/OS™</span> does
|
||
not use this field.</p>
|
||
</li>
|
||
<li>Version Number (not used) <p>If the data set is part of a generation
|
||
data group, this field contains a number indicating the version number of
|
||
the generation. <span class="keyword">i5/OS</span> does
|
||
not use this field.</p>
|
||
</li>
|
||
<li>Creation Date <p>The creation date of the data set. the program shows
|
||
the date in the format cyyddd, where:</p>
|
||
<p> c = century (blank=19; 0=20;
|
||
1=21; and so on)</p>
|
||
<p> yy = year (00-99)</p>
|
||
<p>ddd = day of the current
|
||
year (001-366)</p>
|
||
<p>Note that the century code gives the first two digits
|
||
of the year, not the actual century. For example, a blank which translates
|
||
into 19 indicates a year in the 1900s, not in the nineteenth century.</p>
|
||
</li>
|
||
<li>Expiration Date <p>The program considers the date in which the data set
|
||
expires. Expired refers to a data set being allowed to be overwritten. The
|
||
user specifies the date in the open tape file used in writing the tape. The <span class="keyword">i5/OS</span> ignores
|
||
the expiration date on input, and verifies the expiration date on output.
|
||
The date is in the format cyyddd, where:</p>
|
||
<p> c = century (blank=19; 0=20;
|
||
1=21; and so on)</p>

<li>Accessibility <div class="p">A code number indicating the security status of the
