<h1 class="topictitle1">VALNUM (Validate Numeric) keyword for display files</h1>
|
|
<div><p>Use this file-, record-, or field-level keyword to enhance the
|
|
error checking performed against fields with the data type numeric only.</p>
|
|
<div class="section"><p>When specified on a numeric only field, this keyword causes an
|
|
error message to be returned if the user attempts to embed a SPACE, PLUS SIGN
|
|
or MINUS SIGN between numeric digits in the field or when the PLUS SIGN or
|
|
MINUS SIGN precedes the numeric digits.</p>
|
|
<p>This keyword has no parameters.</p>
|
|
<p>The
|
|
field containing the VALNUM keyword must be defined as an input-capable field
|
|
with the data type Y.</p>
|
|
<p>Option indicators are not valid for this keyword.</p>
|
|
</div>
|
|
<div class="example"><h4 class="sectiontitle">Example</h4><p>The following example shows how to specify
|
|
the VALNUM keyword:</p>
|
|
<pre>|...+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
|
|
00010A R RECORD
|
|
00020A F1 5Y 0B 3 4VALNUM
|
|
00030A F2 5Y 0B 4 4</pre>
|
|
<p>In this example,
|
|
field F1 will not allow the user to embed a SPACE, the PLUS SIGN or MINUS
|
|
SIGN within the numeric value or precede the numeric value with a PLUS SIGN
|
|
or MINUS SIGN. Field F2 will be treated as described in the <a href="rzakcmstdfdt.htm">Data type/keyboard shift for display files (position 35)</a> topic.</p>
