<P>The <A NAME="idx:usemodule1:1267"></A><A class="pred" href="import.html#use_module/1">use_module/1</A> 
predicate from <A class="sec" href="import.html">section 5.3</A> defines 
import and export relations based on the filename from which a module is 
loaded. If modules are created differently, such as by asserting 
predicates into a new module as described in <A class="sec" href="dynamic-modules.html">section 
5.12</A>, this interface cannot be used. The interface below provides 
for import/export from modules that are not created using a module-file.

<DL class="latex">
<DT class="pubdef"><A NAME="export/1"><STRONG>export</STRONG>(<VAR>+PredicateIndicator, 
...</VAR>)</A></DT>
<DD class="defbody">
Add predicates to the public list of the context module. This implies 
the predicate will be imported into another module if this module is 
imported with <A NAME="idx:usemodule12:1268"></A><A class="pred" href="import.html#use_module/1">use_module/[1,2]</A>. 
Note that predicates are normally exported using the directive <A NAME="idx:module2:1269"></A><A class="pred" href="defmodule.html#module/2">module/2</A>. <A NAME="idx:export1:1270"></A><A class="pred" href="sec-5.11.html#export/1">export/1</A> 
is meant to handle export from dynamically created modules.</DD>
<DT class="pubdef"><A NAME="import/1"><STRONG>import</STRONG>(<VAR>+PredicateIndicator, 
...</VAR>)</A></DT>
<DD class="defbody">
Import predicates <VAR>PredicateIndicator</VAR> into the current context 
module. <VAR>PredicateIndicator</VAR> must specify the source module 
using the &lt;<VAR>module</VAR>&gt;:&lt;<VAR>pi</VAR>&gt; construct. 
Note that predicates are normally imported using one of the directives <A NAME="idx:usemodule12:1271"></A><A class="pred" href="import.html#use_module/1">use_module/[1,2]</A>. 
The <A NAME="idx:import1:1272"></A><A class="pred" href="sec-5.11.html#import/1">import/1</A> 
alternative is meant for handling imports into dynamically created 
modules. See also <A NAME="idx:export1:1273"></A><A class="pred" href="sec-5.11.html#export/1">export/1</A> 
and <A NAME="idx:exportlist2:1274"></A><SPAN class="pred-ext">export_list/2</SPAN>.
