Parameters holding the typecode value are generated for all parsed IDL types. If the IDL parser generates a Lisp type of nameA:B, then the typecode of the given type is available in the parameterA:_TC_B.
For example, the IDL code
module example { interface array_interface{}};
leads to the definition of a parameter
example:_tc_array_interface
with
(op:kind example:_tc_array_interface) > :tk_objref
