|

<div class="section"><p>The program used by KAREN accesses a DDM file named LOCFILEX that

|
||
|
|
DDM sends a request to the target server to open RMTFILEX in LIBX for input
|
||
|
|
operations. From this information, the target server builds the following
|
||
|
|
parameter list to be used by the user exit program for verification: <pre>KAREN *DDM OPEN RMTFILEX LIBX *N 0 24 CHICAGO NEWYORK 1000</pre>

<div class="section"><p>This parameter list shows only the significant characters that
|
||
|
|
would be sent in each field; all the padded blanks and zeros are not shown.
|
||
|
|
For example, the field containing KAREN is padded with five blanks because
|
||
|
|
it is a 10-character field. This parameter list is sent only for the open
|
||
|
|
operation, although several input operations might be performed on RMTFILEX.</p>

on the DDMACC parameter of the <span class="cmdname">Change Network Attributes (CHGNETA)</span> command.
|
||
|
|
The user exit program determines if user KAREN is authorized to open RMTFILEX.
|
||
|
|
If she is authorized, the program returns a 1 in the return code field, and
|
||
|
|
she can open the file and perform read operations. If the program returns
|
||
|
|
a 0 in the return code field, user KAREN receives a message in the job log

indicating that she is not authorized to use the file.</p>
