<div><p>Use this record-level keyword with the OVERLAY keyword to specify
|
||
|
|
that the records whose names you supplied as parameter values are to be erased
|
||
|
|
from the display when this record is written.</p>
|
||
|
|
<div class="section"><div class="p">The format of the keyword is: <pre>ERASE(record-name-1 [record-name-2 ...[record-name-20]])</pre>
|
||
|
|
</div>
|
||
|
|
<p>The
|
||
|
|
record formats specified as parameter values must exist in the file.</p>
|
||
|
|
<p>ERASE
|
||
|
|
can be specified more than once. The OVERLAY keyword must be specified whenever
|
||
|
|
the ERASE keyword is specified.</p>
|
||
|
|
<p>If the ERASE and CLRL keywords are both
|
||
|
|
in effect on an output operation, the records specified in the ERASE keyword
|
||
|
|
are erased despite the CLRL keyword.</p>
|
||
|
|
<p>A record already on the display
|
||
|
|
that has no input-capable fields and that has the CLRL specified cannot be
|
||
|
|
erased by the ERASE keyword on another record (ERASE has no effect).</p>
|
||
|
|
<p>If
|
||
|
|
the specified record is not on the display, this function is ignored for that
|
||
|
|
record name.</p>
|
||
|
|
<p>Option indicators are valid for this keyword.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> This
|
||
|
|
function requires extra data transmission and should be used only when you
|
||
|
|
do not want to erase all other record formats. You can also specify the OVERLAY
|
||
|
|
keyword with option indicators so that you can select when to erase all other
|

|
|
formats.</div>
