Abstract

It is shown that there exists an infinite hierarchy of syntax-directed translations according to the number of nonterminals allowed on the right side of productions of the underlying context-free grammar. A device called the pushdown assembler is defined, and it is shown capable of performing exactly the syntax-directed translations.
