<h1 class="topictitle1">MNUCNL (Menu-Cancel Key) keyword for display files</h1>
|
||
|
|
<div><p>Use this file- or record-level keyword to assign a CA key to be
|
||
|
|
the cancel key for menu bars or pull-down menus.</p>
|
||
|
|
<div class="section"><p>When the MNUCNL keyword is active and a pull-down menu is displayed,
|
||
|
|
pressing the CA key cancels the pull-down menu and returns the cursor to the
|
||
|
|
choice in the menu bar. If no pull-down menu is displayed and the cursor is
|
||
|
|
located in the menu bar, pressing the CA key cancels the menu bar and returns
|
||
|
|
the cursor to the application screen. If no pull-down menu is displayed and
|
||
|
|
the cursor is on the application screen, pressing the CA key returns control
|
||
|
|
to the application.</p>
|
||
|
|
<div class="p">The format of the keyword is: <pre>MNUCNL[(CAnn [response-indicator])]</pre>
|
||
|
|
</div>
|
||
|
|
<p>The
|
||
|
|
CAnn parameter is optional. If not specified, the default is CA12. Valid values
|
||
|
|
are CA01 through CA24.</p>
|
||
|
|
<p>The response-indicator parameter is optional.
|
||
|
|
The parameter is set on when the MNUCNL keyword is active on a record other
|
||
|
|
than a menu bar or pull-down menu, and control is being returned to the application.</p>
|
||
|
|
<p>Within
|
||
|
|
a record, the CAnn key specified by the MNUCNL keyword cannot be specified
|
||
|
|
again using another keyword (such as MNUBARSW). Because MNUCNL at the file-level
|
||
|
|
extends to all records in the file, this must be considered when assigning
|
||
|
|
a CAnn key.</p>
|
||
|
|
<p>If the MNUCNL keyword is specified on the record, the CAnn
|
||
|
|
key or default CA12 key can be used only as a CA key on other records, not
|
||
|
|
as a CF key.</p>
|
||
|
|
<p>The MNUCNL keyword is allowed only in a file containing
|
||
|
|
a menu-bar record.</p>
|
||
|
|
<p>Option indicators are valid for this keyword.</p>
|
||
|
|
</div>
|
||
|
|
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
||
|
|
the MNUCNL keyword:</p>

|
<p>In this example, CA12
|
||
|
|
is defined as the cancel key for all records in the file. If CA12 is pressed
|
||
|
|
while the pull-down menu, PULLEDIT, is displayed, the pull-down menu is canceled.
|
||
|
|
If CA12 is pressed while the cursor is located on the menu bar (no pull-down
|
||
|
|
menus are displayed), the menu bar is canceled and the cursor is moved back
|
||
|
|
to the application record. If CA12 is pressed while the cursor is not located
|
||
|
|
on the menu bar and no pull-down menu is displayed, response indicator 12
|
||
|
|
is set on and control is returned to the application program.</p>
