<h1 class="topictitle1">CHKMSGID (Check Message Identifier) keyword for display files</h1>
|
||
|
|
<div><p>Use this field-level keyword to identify an error message that
|
||
|
|
is issued when a validity check error is detected.</p>
|
||
|
|
<div class="section"><p>If you do not specify the CHKMSGID keyword, the system supplies
|
||
|
|
a message. You specify the associated validity checking rules on a CHECK(M10),
|
||
|
|
CHECK(M11), CHECK(VN), CHECK(VNE), CMP, COMP, RANGE, or VALUES keyword.</p>
|
||
|
|
<p>The
|
||
|
|
format of the keyword is:</p>
|
||
|
|
<pre>CHKMSGID(message-id [library/]message-file [&message-data-field])</pre>
|
||
|
|
<p>The
|
||
|
|
message-ID parameter specifies the message description that contains the text
|
||
|
|
to be displayed on the message line.</p>
|
||
|
|
<p>The message-file and library parameters
|
||
|
|
identify the message file containing the message descriptions. The library
|
||
|
|
name is optional. If it is not specified, the library list (*LIBL) that is
|
||
|
|
in effect at run time is used to search for the message file.</p>
|
||
|
|
<p>The message-data-field
|
||
|
|
parameter specifies the name of the field that contains the message replacement
|
||
|
|
text to be displayed on the message line. The format of the message-data-field
|
||
|
|
parameter is &field-name where field-name is the name of the field containing
|
||
|
|
the message replacement text. The field name must exist in the record format,
|
||
|
|
and the field must be defined as a character field (data type A) with usage
|
||
|
|
P.</p>
|
||
|
|
<p>CHKMSGID is allowed only on fields which also contain a CHECK(M10),
|
||
|
|
CHECK(M11), CHECK(VN), CHECK(VNE), CMP, COMP, RANGE, or VALUES keyword. The
|
||
|
|
field must be input-capable (usage B or I).</p>
|
||
|
|
<p>Option indicators are not
|
||
|
|
valid for this keyword.</p>
