the transfer of a full High Level COBOL compiler designed for the IBM S/370 to a Low-Intermediate Level on a 32-bit minicomputer. The major impacts of language feature deletion upon compiler size and complexity, as well as the effects of specific compiler and object code support via micro-coding, are discussed. micro computer and small minicomputer assemblers and simulators. It is simple enough to be used by those with limited architecture and programming backgrounds, but flexible and powerful enough to generate efficient and well-structured assemblers and simulators for small micro/mini computers with sophisticated architectures and instruction sets. This paper presents a brief description of the generating system, the g~nerated assemblers and simulators and the advantages they offer in both programming and pedagogical applications. 0PTIMIZEDMACHINE-INDEPENDENT EXTENDED FORTRAN FOR MINICOMPUTER PROGRAMMING Gordon Bennett-Novak Tractor, Inc., and The University of Texas at Austin AN INTEGRATED MICROPROCESSOR SUPPORT SOFTWARE SYSTEM Abstract A FORTRAN compiler is being developed to aid in writing systems and application programs for minicomputers. The compiler is machineindependent in the sense that it can be made to generate code for a new machine with relatively little effort. The FORTRAN language accepted by the compiler is extended to facilitate the writing of "systems" programs. Particular emphasis is placed on optimization of the generated code for efficiency of storage utilization. Christine L. Braun Raytheon Company Missile Systems Division Bedford, Massachusetts Abstract As the commercial use of microprocessors increases, the need for various support software tools arises. These tools include assemblers to aid in the creation of programs, and digital simulators to aid in their checkout. Raytheon's Automatic Micro Processor Support (RAMPS) system is an integrated set of support software programs designed to take advantage of the microprogrammable aspect of the target processor. There are three main components of the RAMPS system - a micro-assemb]er, a macro-assembler, and a digital simulator. In addition there is a control system, through which the user communicates with all parts of the system. RAMPS is designed to be independent of the particular macro-instruction set determined by the microprogram, insofar as is possible. Thus, it is a versatile system which can be used with any of the various macro-instruction sets developed for the target machine. The RAMPS system is written in FORTRAN and runs on the CDC 6700 computer under the KRONOS 2.1 Operating System. Designed to support a Raytheonbuilt microprocessor, its flexibility has already been demonstrated by adaptation to two new, architecturally similar, microprocessors.
