the following points:</p>

<ol><li>For the first output operation, the user program sets
|

|
|
off option indicator 77. Therefore, the PUTOVR, ERASEINP, and INZINP keywords
|
||
|
|
are not in effect. This has the following effect:<ul><li>Fields NAME, ADDR1, and ADDR2 are sent to the workstation.</li>

<li>The input save area contains: <dl><dt class="dlterm">CUSNBR</dt>

<li>For the second output operation, the user program sets on option indicator
