Abstract

Benkard explains the precedence rules of APL with a syntactic binding hierarchy [1,2]. This paper uses the hierarchy as a basis for developing a more formal description of APL syntax which can be applied directly in a syntax analyzer. The flexibility of this approach makes it useful as a basis for examining the effect of proposed syntax changes and the consequences of previous design choices.
