The LL grammars play important role in the programming languages description. The construction of their efficient and simple analyzers (pushdown automata) is limited to the LL(1) grammars, however. The descriptive power of these grammars is quite low and, in addition, there are problems with analysis of the LL(k+1), k>=1, grammars. This paper presents algorithm that allows transformation from pushdown automaton with (k+1)-symbol reading head used for LL(k+1) language analysis to the one-symbol reading head pushdown automaton. Thus, we can simulate a function of the former by using much simpler constructs of the latter.
