This paper describes a hybrid compiler system which enables a user to program the analog and digital portions in a homogeneous language. The features of a well-suited language are deduced. The boundary of the analog and digital regions is optional. It is shown that this degree of freedom is necessary to permit transfer of programs from one machine to another. The compiler requires use of an autopatch system which is described. An algorithm is presented for mapping the analog part of the problem into the switching network of the autopatch system.
