Abstract

Some difficulties in reading and writing APL programs are discussed. Assertions (important relations among and properties of variables) are suggested as a technique for improving reliability and readability of APL programs. It is shown how such assertions may be used for documentation, verification, optimization, and debugging. An implementation of run-time assertions in APLSV is given and illustrated by examples.
