<h1 class="topictitle1">Use source files in a program</h1>
|
|
<div><p>You can process a source file in your program. You can use the
|
|
external definition of the source file and do any input/output operations
|
|
for that file, just as you would for any other database file.</p>
|
|
<div class="p">Source files are externally described database files. As such, when you
|
|
name a source file in your program and compile it, the source file description
|
|
is automatically included in your program printout. For example, assume you
|
|
wanted to read and update records for a member called FILEA in the source
|
|
file QDDSSRC. When you write the program to process this file, the system
|
|
will include the <em>SRCSEQ</em>, <em>SRCDAT</em>, and <em>SRCDTA</em> fields from
|
|
the source file. <div class="note"><span class="notetitle">Note:</span> You can display the fields defined in
|
|
a file by using the Display File Field Description command (DSPFFD). </div>
|
|
</div>
|
|
<div class="p">The program processing the FILEA member of the QDDSSRC file can: <ul><li>Open the file member (just like any other database file member).</li>
|
|
<li>Read and update records from the source file (probably changing the <em>SRCDTA</em> field
|
|
where the actual source data is stored).</li>
|
|
<li>Close the source file member (just like any other database file member).</li>
