<h1 class="topictitle1">SFLFOLD (Subfile Fold) keyword for display files</h1>
|
||
|
|
<div><p>Use this record-level keyword on the subfile control record format
|
||
|
|
to assign a command attention (CA) or a command function (CF) key that the
|
||
|
|
workstation user can press to truncate or to fold subfile records that require
|
||
|
|
more than one display line.</p>
|
||
|
|
<div class="section"><div class="p">The format of the keyword is: <pre>SFLFOLD(CAnn | CFnn)</pre>
|
||
|
|
</div>
|
||
|
|
<p>When
|
||
|
|
the SFLFOLD keyword is specified, the subfile is first displayed in folded
|
||
|
|
form. When the workstation user presses the specified key, the <span class="keyword">i5/OS™</span> operating system
|
||
|
|
displays the records again in truncated form. By pressing the specified key,
|
||
|
|
the form of the displayed subfile changes from one state to the other. When
|
||
|
|
truncated, subfile records fit on one display line.</p>
|
||
|
|
<p>Without SFLFOLD,
|
||
|
|
the <span class="keyword">i5/OS</span> operating system displays
|
||
|
|
the entire subfile record folded where needed but the workstation user is
|
||
|
|
not given the option to display the subfile record in truncated form.</p>
|
||
|
|
<p>In
|
||
|
|
the folded form, as many records are displayed as are specified on the SFLPAG
|
||
|
|
keyword. In the truncated form, more records are displayed than are specified
|
||
|
|
on the SFLPAG keyword.</p>
|
||
|
|
<div class="p">The <span class="keyword">i5/OS</span> operating system
|
||
|
|
truncates subfile records in the middle of output-only fields. However, if
|
||
|
|
the truncation is in the middle of an input-capable field, the whole field
|
||
|
|
is omitted from the display. If this results in omitting the entire record
|
||
|
|
from the display, an error message is sent to the display and the record is
|
||
|
|
not truncated. Instead, it is displayed in folded form. <div class="note"><span class="notetitle">Notes:</span> <ol><li>A warning message (severity 10) is sent at file creation if the entire
|
||
|
|
record fits on a single display line.</li>
|
||
|
|
<li>If subfile size equals subfile page, an error message (severity 20) is
|
||
|
|
issued and SFLFOLD is ignored. When several display sizes are used (DSPSIZ
|
||
|
|
keyword specified), SFLFOLD is ignored only for display sizes for which the
|
||
|
|
subfile size equals subfile page. If the subfile record format contains field
|
||
|
|
selection, SFLFOLD is not valid.</li>
|
||
|
|
<li>If the subfile contains input-capable fields, it is recommended that you
|
||
|
|
specify a CF key rather than a CA key. If you specify a CA key in this situation,
|
||
|
|
changed data is lost when the key is pressed.</li>
|
||
|
|
<li>If several subfiles using SFLFOLD are displayed at one time, the same
|
||
|
|
function key should be specified on each SFLFOLD keyword. If the function
|
||
|
|
keys are different, only the key specified for the most recently displayed
|
||
|
|
subfile is in effect. Pressing the function key affects the subfile containing
|
||
|
|
the cursor. If the cursor is not positioned in a subfile, the function key
|
||
|
|
affects the upper subfile.</li>
|
||
|
|
<li>SFLFOLD can be specified on the same subfile control record format as
|
||
|
|
the SFLDROP keyword. If both keywords are active, SFLFOLD is used. Indicators
|
||
|
|
are checked at the time the subfile is displayed. Both keywords must use the
|
||
|
|
same key.</li>
