|
|
<div><p>Initially, the ORDERENT program exists only in library PGMLIB on
|
|||
|
|
the central server (in Philadelphia).</p>
|
|||
|
|
<div class="section"><p>This program does the following items:</p>
|
|||
|
|
<ul><li>When an order entry operator enters a customer number, ORDERENT reads
|
|||
|
|
the customer number, then reads the first member of file CUSTMST2 in the PGMLIB
|
|||
|
|
library to find the customer name, address, and other information. The retrieved
|
|||
|
|
information is displayed to the operator, and the program asks for an item
|
|||
|
|
number and quantity desired.</li>
|
|||
|
|
<li>When the operator enters an item number and quantity desired and presses
|
|||
|
|
the Enter key, the program changes the corresponding primary item in the first
|
|||
|
|
member of the INVEN file, and it adds a record to the DETAIL file for each
|
|||
|
|
item and quantity entered. The program continues asking for another item number
|
|||
|
|
and quantity until the operator ends the program.</li>
|
|||
|
|
<li>When the operator ends the program, the file CUSTMAST is changed with
|
|||
|
|
the information for the entire order. (See the pseudocode of ORDERENT for
|
|||
|
|
details.)</li>
|
|||
|
|
</ul>
|
|||
|
|
</div>
|
|||
|
|
<div class="section"><p>For the following examples, it is assumed that all users on the
|
|||
|
|
remote servers who need to access CUSTMAST in Philadelphia already have authority
|
|||
|
|
to do so, and that those who do not need authority do not have it. In these
|
|||
|
|
examples, the <span class="keyword">iSeries™ server</span> in Chicago
|
|||
|
|
does not have a compiler.</p>
|
|||
|
|
</div>
|
|||
|
|
<div class="section"><p>If we want this program to be used at all the remote locations
|
|||
|
|
that also stock a physical inventory, the program needs to be sent to each
|
|||
|
|
of the remote servers. We can assume that each of the remote servers has its
|
|||
|
|
own inventory and primary files INVEN, DETAIL, and CUSTMST2 (which is a copy
|
|||
|
|
of CUSTMAST). How the program can be sent to a remote server is described
|
|||
|
|
in <a href="rbae5tsk1.htm#rbae5tsk1">DDM example 2: Transfer a program to a target server</a>.</p>
