Abstract

Standard Lisp on IBM 360 & 370 proposed and implemented by A. C. Hearn and J. Fitch et al. of the University of Utah had still several bugs and some execution-time inefficiency. This paper describes these bug-fixings, modifications and additions of comfortable features, and some improvements in the stack operation and compiler-interface which contribute to a speed-up of the factor of about 1.2~1.6. It also urges the necessity of variety of datatypes for a more practical Lisp system, such as vectors, hash tables, bit/byte strings.
