Originální abstrakt

The LL grammars play important role in the programming languagesdescription. 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.
