<h1 class="topictitle1">SFLRCDNBR (Subfile Record Number) keyword for display files</h1>
|
|
<div><p>Use this field-level keyword on the subfile control record format
|
|
to specify that the page of the subfile to be displayed is the page containing
|
|
the record whose relative record number is in this field.</p>
|
|
<div class="section"><p>If you do not specify this keyword, the <span class="keyword">i5/OS™</span> operating system
|
|
displays the first page of the subfile by default.</p>
|
|
<div class="p">The format of the
|
|
keyword is: <pre>SFLRCDNBR[([CURSOR] [*TOP])]</pre>
|
|
</div>
|
|
<p>If
|
|
CURSOR is specified, the cursor is placed in the subfile record whose relative
|
|
record number is identified by the contents of this field. The cursor is positioned
|
|
at the first input-capable field in the subfile record. If there is no input-capable
|
|
field, the cursor is positioned at the first output-only or constant field.
|
|
For example, if a page can contain three records, and nine records are contained
|
|
in the subfile, a SFLRCDNBR field value of 8 causes records 7, 8, and 9 to
|
|
be displayed. If CURSOR is specified, the cursor appears in record 8.</p>
|
|
<p>If
|
|
*TOP is specified, the subfile record whose relative record number is identified
|
|
by the contents of this field will display as the first record of the page
|
|
of the subfile records being displayed.</p>
|
|
<p>This field must be a zoned decimal
|
|
field with zero decimal positions. It must have the keyboard shift attribute
|
|
of signed numeric (S in position 35), and it can be up to 4 digits in length.
|
|
It must be defined as an output-only, an input/output, or a hidden field.
|
|
If a value less than 1 or a value greater than the number of records in the
|
|
subfile is contained in this field on an output operation to the subfile control
|
|
record format, an error is returned to your program.</p>
|
|
<p>This optional keyword
|
|
is valid only for the subfile control record format.</p>
|
|
<p>You cannot specify
|
|
both SFLRCDNBR and SFLROLVAL for the same field.</p>
|
|
<p>If the subfile record
|
|
format contains field selection, this keyword is not allowed.</p>
|
|
<p>Option
|
|
indicators are not valid for this keyword.</p>
|
|
</div>
|
|
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
|
the SFLRCDNBR keyword.</p>
|
|
<pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
