The theory is quantized in conformal gauge, following David, and Distler and Kawai. There is no analogue of the $c=1$ barrier found in nonchiral non-critical strings. A non-critical heterotic string is constructed---it has 744 states in its spectrum, transforming in the adjoint representation of $(E_8)^3.$ Correlation functions are calculated in this example, revealing the existence of extra discrete states.13 pages (LaTeX) ( Talk reviews material in hep-th/9207117, and also gives new results on correlation functions. )High Energy Physics - Theorytext
