You can open a database file member with statements in your high-level language program. You can also use the control language (CL) open commands: Open Database File (OPNDBF) and Open Query File (OPNQRYF).</li>
|
|
<li class="ulchildlink"><strong><a href="rbafoopndbf.htm">Use Open Database File (OPNDBF) command</a></strong><br />
|
|
Usually, when you use the Open Database File (OPNDBF) command, you use the defaults for the command parameter values. Sometimes you might want to specify particular values, instead of using the default values. Listed here are the parameters you can specify.</li>

|
<li class="ulchildlink"><strong><a href="rbafoopnqf.htm">Use Open Query File (OPNQRYF) command</a></strong><br />
|
|
The Open Query File (OPNQRYF) command is a control language (CL) command that allows you to perform many data processing functions on database files. These topics discuss how to create a query using the OPNQRYF command, how to specify parameters for its major functions, and how to use it with your high-level language program.</li>
