Abstract
A threaded interpretive language (TIL), Forth, was utilized to im plement HeartLab, a simulation-based program designed to teach medical students the essentials of the auscultatory cardiac exam. The simulation output, high-resolution bit-mapped graphics cou pled with realistic, computer-generated heart sounds, makes full use of the Apple Macintosh sound and graphics capabilities. Multimode simulation of this type and construction of an ap propriate patient model create a number of design challenges for which this approach proved to be particularly well suited.
