|
||
<div><p>Specify this field-level keyword to change input- and output-capable
|
||
alphanumeric character fields to DBCS fields with data type O.</p>
|
||
<div class="section"><p>This keyword has no parameters.</p>
|
||
<p>Put the keyword into effect
|
||
by specifying IGCDTA(*YES) on the CRTDSPF, CHGDSPF, and OVRDSPF commands.
|
||
Fields specified with this keyword are DBCS fields when you specify IGCDTA(*YES)
|
||
and are alphanumeric character fields when you specify IGCDTA(*NO). For example,
|
||
you can create the file by specifying IGCDTA(*NO) on the CRTDSPF command.
|
||
When using the file to display DBCS data, override the file with the OVRDSPF
|
||
command, specifying IGCDTA(*YES). To override the display file IGCDSPF, type: <kbd class="userinput">OVRDSPF
|
||
FILE(IGCLIB/IGCDSPF) IGCDTA(*YES)</kbd></p>
|
||
<p>Consider
|
||
the following rules, when using the IGCALTTYP keyword:</p>
|
||
<ul><li>Specify this keyword only for input- and output-capable fields whose keyboard
|
||
shift type is A, N, X, W, or I. Do not specify this keyword for DBCS fields.
|
||
<div class="note"><span class="notetitle">Note:</span> Fields specified with IGCDTA(*YES) are recognized as alphanumeric OPEN

data type fields (O) when keyboard shift type is defined as N, X, W, or I.</div>
