<h1 class="topictitle1">SFLDLT (Subfile Delete) keyword for display files</h1>
|
|
<div><p>Use this record-level keyword with an option indicator on the subfile
|
|
control record format to enable your program to delete the subfile.</p>
|
|
<div class="section"><p>When the maximum number of subfiles in a display file is already
|
|
active (24) and another subfile is to be made active, your program must delete
|
|
one of the active subfiles before making another active.</p>
|
|
<p>This keyword
|
|
has no parameters.</p>
|
|
<p>To make a subfile active, your program sends an output
|
|
operation to the subfile record format or sends an output operation to the
|
|
subfile control record format with the SFLINZ keyword in effect. To delete
|
|
a subfile, your program sends an output operation to the subfile control record
|
|
format with SFLDLT in effect. (Closing the display file deletes all the active
|
|
subfiles.)</p>
|
|
<p>If your program sends an output operation with SFLDLT in
|
|
effect to a subfile that is not active, the SFLDLT keyword is ignored.</p>
|
|
<p>Option
|
|
indicators are required for this keyword; display size condition names are
|
|
not valid.</p>
|
|
</div>

<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify

the SFLDLT keyword.</p>

<p>The subfile is displayed when option indicator 01 is

set on for an output operation to SFLCTLR, and the subfile is deleted when
|
|
option indicator 04 is set on for an output operation to SFLCTLR. Normally,
|
|
the option indicators specified for SFLDLT are different from the option indicators
|
|
specified for the SFLDSP and SFLDSPCTL keywords.</p>
