This paper provides a method for generating compact and efficient code to implement the enforcement of a description in typed feature logic. It does so by viewing information about types through the course of code generation as modes of instantiation --- a generalization of the common practice in logic programming of the binary instantiated/variable mode declarations that advanced Prolog compilers use. Section 1 introduces the description language. Sections 2 and 3 motivate the view of mode and compilation taken here, and outline a mode declaration language for typed feature logic. Sections 4 through 7 then present the compiler. An evaluation on two grammars is presented at the end.
