<TD>Symbol table for functions</TR></table><h2>Description</h2><P>To use JavaScript, you must first open an interpreter session
with <i>ejOpen</i>. JavaScript interpreters usually have their own
variable and global function name space. To share variable or function
name space, pass a symbol table into <b>ejOpen</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>ejClose</b> to close the interpreter when finished.
<h2>Return Value</h2><p>Handle for the JavaScript interpreter.</p><h2>Example</h2><pre>
if (ejOpen(NULL, NULL)< 0) {
/* Cant open interpreter */
return -1;
}
