<p> Sets a string value of a specific parameter option.
</p>
<h3>Parameters</h3>
<p><i>sOptionName</i>. A string key of the parameter option.<p>
<h3>Remarks</h3>
<p>
Call this method to set
value(s) of server specific parameter options. See <STRONG>Server specific
notes</STRONG>.
<P>A parameter related option may be specified
in <A href="Connection.html">SAConnection</A>
object, <A href="Command.html">SACommand</A>
object or <A href="Param.html">SAParam</A>
object. If it is specified in <A href="Connection.html">SAConnection</A>
object it affects all
the commands and therefore all the parameters on that connection. If
it is specified in <A href="Command.html">SACommand</A>
object it affects all the
parameters on that command. </P>
<p>If an option is not specified in <A href="Connection.html">SAConnection</A>,
<A href="Command.html">SACommand</A>
and
<A href="Param.html">SAParam</A>
objects,
the Library takes the default option's value. </p>
<p><STRONG>setOption</STRONG> method is safe to
use in cross-server applications. An option related to a particular server
does not affect others.
