The RTE is caused by following DRL.g in writing a function; it says you can omit the type for a parameter. A function like this causes the crash:<br><br>function inf sqr( a ){ return a*a; }<br><br>Untyped parameters may be used in queries. I suppose it will be necessary to use different NTs for parameters and param_definition.<br>
