The following inaccuracies should be noted. All proofs and other results remain unaffected. (1) In Lemma 2.2, page 158, replace “the free continuous Z-algebra over X” by “the initial continuous Z-algebra” and “fre:e complete magma” by “initial complete magma”. (2) Page 160, line 12, replace “the free continuous X-algebra” :by “the initial continuous Z-algebra”. (3) Theorem 3.2 (page 163) is incompletely stated and should read as Theorem 3.2. For etie,ryterminal function symbol f occurring in a proper scheme tx, the address language L(f) is accepted by final state by a deterministicpushdown automa ton. For a variable x, L(x) is accepted by final stateand empty store by a determ(iasistic pushdown automaton.
