|
||
|
|
<p>The system provides editing support that makes fields more readable when
|
||
|
|
they are printed. With the system editing support, you can do the following: </p>
|
||
|
|
<ul>
|
||
|
|
<li>Suppress leading zeros</li>
|
||
|
|
<li>Punctuate a field with commas and periods to show decimal column and to
|
||
|
|
group digits in sets of three</li>
|
||
|
|
<li>Print negative values with a minus sign or CR to the right</li>
|
||
|
|
<li>Print zero values as zeros or blanks</li>
|
||
|
|
<li>Print asterisks to the left of significant digits to provide asterisk
|
||
|
|
protection</li>
|
||
|
|
<li>Print a currency symbol corresponding to the system value Currency symbol
|
||
|
|
(QCURSYM)</li></ul>
|
||
|
|
<p>The system provides this editing support with edit codes and edit words.
|
||
|
|
Edit codes are a defined set of editing patterns. You identify these by
|
||
|
|
name, and the system edits a field according to the pattern defined by the
|
||
|
|
named edit code. Edit words are edit patterns that you define to produce the
|
||
|
|
results that you want. Edit codes include most commonly used editing requirements.
|
||
|
|
You need to use the edit word support only for those editing needs not included
|
||
|
|
by edit codes.</p>
|
||
|
|
<p>There are two methods of using edit codes and edit words. Which one you
|
||
|
|
use depends on how you define the printer file and how it is used in an application
|
||
|
|
program. If your application is using program-described data, your high-level
|
||
|
|
language might allow you to identify edit codes or create your own edit words.
|
||
|
|
If your application is using externally described data, the edit code (EDTCDE)
|
||
|
|
DDS keyword allows you to identify an edit code; the edit word (EDTWRD) DDS
|
||
|
|
keyword allows you to define your own editing pattern.</p>
|
||
|
|
<p>The system provides several edit codes: </p>
|
||
|
|
<ul>
|
||
|
|
<li>1 through 4</li>
|
||
|
|
<li>A through D</li>
|
||
|
|
<li>J through M</li>
|
||
|
|
<li>X through Z</li></ul>
|
||
|
|
<p>The editing patterns defined by these codes are described in <a href="../rzahg/rzahgdds.htm">DDS Reference</a> in the Programming topic.</p>
|
||
|
|
<p><span class="bold">User-defined edit codes</span></p>
|
||
|
|
<p>You can also define five edit codes to provide more editing function than
|
||
|
|
is available with the i5/OS edit codes, and to handle common editing functions
|
||
|
|
that would otherwise require the use of an edit word. These are called user-defined
|
||
|
|
edit codes. For example, you might need to edit numbers that include hyphens
|
||
|
|
(like some telephone numbers), or more than one decimal point. You can use
|
||
|
|
user-defined edit codes for these functions. These edit codes are named QEDIT5,
|
||
|
|
QEDIT6, QEDIT7, QEDIT8, and QEDIT9 and can be referred to in DDS or a high-level
|
||
|
|
language program by number (5, 6, 7, 8, or 9).</p>
|
||
|
|
<p>These edit codes are created by using the Create Edit Description (CRTEDTD)
|
||
|
|
command. Edit descriptions are always placed in library QSYS. They cannot
|
||
|
|
be moved or renamed; only one occurrence of each is allowed. Edit descriptions
|
||
|
|
have an object type of *EDTD.</p>
|
||
|
|
<p>IBM® supplies a version of each of the QEDIT edit codes. You can use
|
||
|
|
these edit descriptions as they are, or you can delete them and create your
|
||
|
|
own. See <a href="../rzahg/rzahgdds.htm">DDS Reference</a> in the Programming topic for
|
||
|
|
more information about using these edit descriptions.</p>
|
||
|
|
<p>Before using any of the user-defined edit codes, you should check its contents
|
||
|
|
on your system, since it might have been changed from the IBM-supplied version.
|
||
|
|
The Display Edit Description (DSPEDTD) command can be used to display the
|
||
|
|
contents of a user-defined edit code.</p>
|
||
|
|
<p>Changing a user-defined edit code description does not affect any application
|
||
|
|
or printer file that has already been created using that edit description.
|
||
|
|
If you want your application to use the changed edit description, you must
|
||
|
|
either create the high-level language program again (if the edit code is used
|
||
|
|
in the program) or create the file again (if the application is using an externally
|
||
|
|
described file that contains EDTCDE keywords).</p>
