<h1 class="topictitle1">SFLRNA (Subfile Records Not Active) keyword for display files</h1>
|
||
|
|
<div><p>Use this record-level keyword with the Subfile Initialize (SFLINZ)
|
||
|
|
keyword on the subfile control record format so that your program can initialize
|
||
|
|
a subfile with no active records. To do this, your program sends an output
|
||
|
|
operation to the subfile control record format with the SFLINZ keyword selected.</p>
|
||
|
|
<div class="section"><div class="p">The subfile itself becomes active. Subfile records
|
||
|
|
are not considered active unless one of the following conditions occurs: <ul><li>Your program sends an output operation to the subfile record format, placing
|
||
|
|
data in one of the subfile records. The subfile record becomes active but
|
||
|
|
is not considered changed unless the SFLNXTCHG keyword is also in effect.</li>
|
||
|
|
<li>After your program displays the subfile, the workstation user types data
|
||
|
|
into subfile records. The records typed in become active and
|
||
|
|
changed.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>This keyword has no parameters.</p>
|
||
|
|
<p>SFLRNA is normally used
|
||
|
|
so that a program can write some records to the subfile before displaying
|
||
|
|
it, and the workstation user can then add records to the subfile.</p>
|
||
|
|
<div class="p">When
|
||
|
|
your program displays a subfile initialized with the SFLINZ and SFLRNA keywords
|
||
|
|
in effect, fields in inactive records have the following values: <ul><li>Character fields are blank.</li>
|
||
|
|
<li>Numeric fields are zero-filled.</li>
|
||
|
|
<li>An input-only field with a constant value specified has the constant value.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>Your program cannot send an input operation to an inactive subfile
|
||
|
|
record. Issuing a get-next-changed operation to one of the subfile records
|
||
|
|
returns the record only when the record has become active and has been changed.</p>
|
||
|
|
<p>Your
|
||
|
|
program cannot send output operations to active records (SFLRNA not specified).
|
||
|
|
It must send update operations. Also, your program cannot send update operations
|
||
|
|
to inactive records (SFLRNA specified). It must send output operations.</p>
|
||
|
|
<p>The
|
||
|
|
SFLINZ keyword is required when SFLRNA is specified.</p>
|
||
|
|
<p>SFLRNA cannot be
|
||
|
|
specified for a message subfile (identified by the SFLMSGRCD keyword on the
|
||
|
|
subfile record format).</p>
|
||
|
|
<p>If the subfile record format contains field
|
||
|
|
selection, SFLRNA is not valid.</p>
|
||
|
|
<p>Option indicators are not valid for
|
||
|
|
this keyword.</p>
