A list processor LIPQ, upward compatible with LISP 1. 6 but more suitable for short-memory environment, was designed and implemented on PDP-11 as a host language for an artificial intelligence system. Main features of LIPQ are: (1) Quaternary cell is introduced rather than binary cell for higher memory efficiency and data accessibility. (2) A method of explicit use of backing store instead of virtual memory technique, is devised to overcome memory space limitations at a negligible cost of run time speed. (3) Control structure is completely open to the user. (4) Semantic-free, appealing printing format is provided.
