<div><p>Use this field-level keyword for input-capable fields to specify

|
that the <span class="keyword">i5/OS™</span> operating

system is to perform validity checking on the data that the workstation user

|
types into the field.</p>
|
|
<div class="section"><p>The data typed in must be greater than or equal to the lower value,
|
|
and less than or equal to the higher value. Note that the <span class="keyword">i5/OS</span> operating
|
|
system performs this checking only if the field is changed by the workstation
|
|
user or if its changed data tag (MDT) is set on using DSPATR(MDT).</p>
|
|
<div class="note"><span class="notetitle">Note:</span> See
|
|
the <a href="rzakcmstdfchkme.htm">CHKMSGID (Check Message Identifier) keyword for display files</a> topic for information

|
|
<div class="p">The format of the keyword
|
|
is: <pre>RANGE(low-value high-value)</pre>
|
|
</div>
|
|
<p>When the field
|
|
is a character field, the parameter values must be enclosed in single quotation
|

marks. When the field is numeric, single quotation marks must not be specified.</p>
|

<p>You

<p>Option

A</pre>
|
|
<p>FIELD7 and FIELD8 have equivalent RANGE parameter values.
|
|
The reason is that for numeric fields, decimal alignment is based on the number
|
|
of decimal positions specified in positions 36 through 37. For FIELD7 and
|
|
FIELD8, the low value is 0.50 and the high value is 1.00.</p>
|
|
<p>Data entered
|
|
into a numeric field is aligned on the decimal positions specified (in positions
|
|
36 through 37), and leading and trailing blanks are filled with zeros. For
|
|
example, if 1.2 is typed into FIELD9, 00120 is returned to your program. If
|
|
100 is typed into FIELD9, 10000 is returned to your program.</p>
