<div><p>The system checks, when you open the file, if the description of
|
||
|
|
the record format you are using was changed since your program was compiled
|
||
|
|
to an extent that it cannot process the file. </p>
|
||
|
|
<p>The system normally notifies your program of a level check. When you use
|
||
|
|
the create or change file command, you can specify that you want level checking.
|
||
|
|
You can also override the level check attribute defined for the file using
|
||
|
|
the LVLCHK parameter on the Override with Database File (OVRDBF) command.</p>
