<div><p>After the file is opened, the system needs to know where it should
|
||
|
|
start processing the file. You can specify the initial file position with
|
||
|
|
the POSITION parameter.</p>
|
||
|
|
<p>The default is to start just before the first record in the file (the first
|
||
|
|
sequential read operation reads the first record). But, you can
|
||
|
|
tell the system to start at the end of the file, or at a certain record in
|
||
|
|
the middle of the file using the Override with Database File (OVRDBF) command.
|
||
|
|
You can also dynamically set a position for the file in your program. </p>
