<h1 class="topictitle1">MNUBARDSP (Menu-Bar Display) keyword for display files</h1>
|
|
<div><p>Use this record-level keyword to display a menu bar. The MNUBARDSP
|
|
keyword has two formats: one for records that contain the MNUBAR keyword and
|
|
one for records that do not contain a MNUBAR keyword.</p>
|
|
<div class="section"><div class="p">The format for MNUBARDSP when specified on a record that is not
|
|
a menu bar record is: <pre>MNUBARDSP(menu-bar-record &choice-field [&pull-down-input])</pre>
|
|
</div>
|
|
<div class="p">The
|
|
format for MNUBARDSP when specified on a menu bar record is: <pre>MNUBARDSP[(&pull-down-input)]</pre>
|
|
</div>
|
|
<p>The
|
|
menu-bar-record parameter specifies the menu-bar record that is to be displayed
|
|
when this record is written. The menu-bar record must exist in the same file
|
|
as the record you are defining.</p>
|
|
<p>The &choice-field parameter specifies
|
|
the name of a hidden field, which on input contains the number of the choice
|
|
(if any) selected from the menu bar. The field must exist in the record you
|
|
are defining and it must be defined as numeric Y in position 35, usage H,
|
|
length 2, and decimal positions 0.</p>
|
|
<div class="p">The &pull-down-input parameter
|
|
is optional and specifies the name of a hidden field that contains the input
|
|
from the pull-down menu when the pull-down menu contains only a single-choice
|
|
selection field. The field must exist in the record you are defining and it
|
|
must be defined as a length 2, decimal positions 0, and zoned (S in position
|
|
35) field with usage H (hidden). On input, this field contains one of the
|
|
following values: <dl><dt><strong>Value</strong></dt>
|
|
<dd><strong>Meaning</strong></dd>
|
|
<dt class="dlterm">0</dt>
|
|
<dd>No selection made.</dd>
|
|
<dt class="dlterm">n</dt>
|
|
<dd>Choice n in the pull-down menu was selected.</dd>
|
|
<dt class="dlterm">-1</dt>
|
|
<dd>Pull-down record contains something other than the one single-choice selection
|
|
field. You must read the pull-down record to receive its contents.</dd>
|
|
</dl>
|
|
</div>
|
|
<p>Option indicators are valid for the MNUBARDSP keyword,
|
|
and more than one MNUBARDSP keyword can be specified on the record if all
|
|
are optioned. If more than one MNUBARDSP keyword is in effect when the record
|
|
is written, the first one in effect is used.</p>
|
|
</div>
|
|
<div class="example"><h4 class="sectiontitle">Example 1</h4><p>The following example shows how to specify
|
|
the MNUBARDSP keyword on a record that is not a menu bar.</p>

|
|
<p>In this example, if option indicator 01 is on when record
|
|
RECORD1 is written to the display, the system displays the menu bar in record
|
|
MENURCD. When the menu bar is activated and the pull-down menu is selected,
|
|
the number of the menu-bar choice is returned in field MNUCHOICE. If the pull-down
|
|
menu selected contains one single-choice selection field, the choice made
|
|
for that field is returned in field INPUT. Otherwise, field INPUT contains
|
|
-1, indicating that the application must read the pull-down record to receive
|
|
the pull-down input.</p>

<p>If option indicator 01 is on when record MENURCD is written

user selects a pull-down menu from the menu bar, the number of the menu-bar

choice selected is returned in F1 field.</p>
