Translation of nested APL to C++

Abstract

This paper discusses the task of developing a nested APL compiler and puts forward the project of such a compiler. The proposed approach consists of simulating the semantics of APL by using the object-oriented C++ programming language. Different kinds of problems ranging from APL syntax ambiguity to the implementation of nested arrays and the robustness of compiled code are considered and different solutions are proposed. We conclude that it is feasible to develop a robust nested APL compiler, although the problem of performance demands further research.
