</table><h2>Description</h2><P>To use JavaScript, you must first open an interpreter session with <i>ejOpenEngine</i>.
JavaScript interpreters usually have their own variable and global function
name space. To share a variable or function name space, pass a symbol table
into <b>ejOpenEngine</b> in the <i>variable</i> or <i>function</i> parameters.
If either of these parameters are set to NULL, the symbol table will be created
automatically.</P><p>Use <b>ejCloseEngine</b> to close the interpreter when finished.
<h2>Return Value</h2><p>Handle for the JavaScript interpreter.</p><h2>Example</h2><pre>
if (ejOpenEngine(NULL, NULL)< 0) {
/* Can't open interpreter */
return -1;
}
</pre>
