<div><p>This topic discusses display support for inserting shift-control
|
|
characters. Also discussed are the number of extended characters and input
|
|
fields that can be displayed, and the effects of displaying double-byte data
|
|
on alphanumeric workstations.</p>
|
|
<div class="section" id="rbagsdbcsdisplaysup__insertchar"><a name="rbagsdbcsdisplaysup__insertchar"><!-- --></a><h4 class="sectiontitle">Insert shift-control characters</h4><p>The
|
|
system inserts shift-control characters into DBCS-only fields automatically.</p>
|
|
<p>To insert shift-control characters into open fields or either
|
|
fields, follow these steps:</p>
|
|
<ol><li>Position the cursor in the field in which you want to insert double-byte
|
|
data.</li>
|
|
<li>Press the Insert Shift Control Character key (according to your DBCS display
|
|
user's guide).</li>
|
|
</ol>
|
|
<p>The system inserts a pair of shift-control characters
|
|
at the same time. The system leaves the cursor under the shift-in character
|
|
and puts the keyboard in insert mode. Insert double-byte characters between
|
|
the shift-control characters.</p>
|
|
<p>To find out if a field already has the
|
|
shift-control characters, press the Display Shift Control Character key.</p>
|
|
<p>DBCS-graphic
|
|
fields store double-byte characters without requiring the use of shift control
|
|
characters. Shift control characters should not be inserted in graphic fields.</p>

|
|
extended characters</h4><p>The system can display up to 512 different extended
|
|
characters on a Japanese display at one time. Additional extended characters
|
|
are displayed as undefined characters. However, the additional extended characters
|
|
are stored correctly in the system.</p>

<div class="section" xml:lang="en-us" id="rbagsdbcsdisplaysup__numberinputfields"><a name="rbagsdbcsdisplaysup__numberinputfields"><!-- --></a><h4 class="sectiontitle">Number of input fields
|
|
on a display</h4><p>The use of DBCS input fields affects the total number
|
|
of input fields allowed on a display. For a local 5250 display, you can specify
|
|
as many as 256 input fields. However, each three instances of a DBCS field
|
|
reduces the maximum number of fields by one. For example, if there are nine
|
|
DBCS fields on a display, then the maximum is 256 - (9/3) = 253 input fields.</p>

|
|
double-byte data at alphanumeric workstations</h4><p>Alphanumeric displays
|
|
cannot display double-byte data correctly. If you try to display double-byte
|
|
data at an alphanumeric display, the following happens:</p>
|
|
<ul><li>The system sends an inquiry message to that display, asking whether you
|
|
want to continue using the program with double-byte data or to cancel it.</li>
|
|
<li>If you continue using the program, the system ignores the shift-control
|
|
characters and interprets the double-byte characters as though they were single-byte
|
|
characters. The displayed double-byte data does not make sense.</li>
