<h1 class="topictitle1">Bidirectional application support</h1>
|
||
|
|
<div><p>Workstations, display files, and the user interface manager (UIM)
|
||
|
|
provide support for bidirectional applications.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Workstation support</h4><p>Workstations that have the ability
|
||
|
|
to display Arabic and Hebrew character sets also have the ability of right-to-left
|
||
|
|
cursor movement. Right-to-left cursor movement on input fields can be achieved
|
||
|
|
in one of the following ways:</p>
|
||
|
|
<ul><li>Pressing a special function key available on Hebrew and Arabic keyboards
|
||
|
|
called the reverse key. This is a toggle function that moves the cursor to
|
||
|
|
the other side of the field, allows for cursor movement in the opposite direction,
|
||
|
|
and also changes the language layer from Latin to Hebrew or Arabic and back
|
||
|
|
again.</li>
|
||
|
|
<li>Using the DDS cursor control codes for display files. When the CHECK keyword
|
||
|
|
is used with a cursor-controlled code, it specifies that the cursor is to
|
||
|
|
move from right to left. The following parameters are valid cursor control
|
||
|
|
codes: <ul><li>CHECK (RL): Moves the cursor from right to left in specified nonnumeric
|
||
|
|
input fields or in all nonnumeric input fields on the display.</li>
|
||
|
|
<li>CHECK (RLTB): Moves the cursor from right to left between fields.</li>
|
||
|
|
</ul>
|
||
|
|
<p>When using these parameters, consider the following
|
||
|
|
information:</p>
|
||
|
|
<ul><li>Modulus check digit verification is supported, but the check digit is
|
||
|
|
the byte to the extreme right of the field.</li>
|
||
|
|
<li>A field for which right-to-left cursor movement is specified can occupy
|
||
|
|
more than one line on the display. However, the cursor still moves from the
|
||
|
|
top of the display to the bottom.</li>
|
||
|
|
<li>You cannot use right-to-left cursor movement with user-defined data streams.</li>
|
||
|
|
</ul>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> If no cursor positioning is specified in the display file or by
|
||
|
|
the program, the cursor is placed in the input-capable field to the extreme
|
||
|
|
left of the top line.</div>
|
||
|
|
</li>
|
||
|
|
</ul>

|
||
|
|
server does not check to make sure that all display files opened to the display
|
||
|
|
station are capable of right-to-left cursor movement. Therefore, it is the
|
||
|
|
responsibility of application programmers to ensure that the proper display
|
||
|

files are used.</p>

|
||
|
|
user interface manager gives the following bidirectional support for creating
|
||
|
|
online information and panels:</p>
|
||
|
|
<ul><li>BIDI= NONE | RTL | LTR <p>This attribute controls the directional orientation
|
||
|
|
of the panels in the panel group.</p>
|
||
|
|
<p>RTL indicates that the panel in the
|
||
|
|
panel group is bidirectional and should be displayed with a right-to-left
|
||
|
|
orientation.</p>
|
||
|
|
<p>LTR indicates that the panel in the panel group is bidirectional
|
||
|
|
and should be displayed with a left-to-right orientation.</p>
|
||
|
|
</li>
|
||
|
|
<li>:RT and :ERT <p>Reverse-direction-text tags indicate that the enclosed
|
||
|
|
text has an orientation that is opposite to the orientation of the panel group.</p>
|
||
|
|
<p>For
|
||
|
|
a list of UIM tags, see the Application Display Programming PDF.</p>
