β¦ Synopsis
A one-to-one correspondence is established between the class of all equal matrix languages and the class of finite-turn checking automata. This checking automaton is provided with a counter in its memory to keep track of the number of turns of the stack-head. Several closure properties of this family are established.

A checking automaton is equivalent to a one-way nonerasing stack automaton which, once it enters its stack, never again writes on its stack. The checking automaton languages (cal) form a full AFL closed under substitution. If L C a\* is an infinite cal, then L contains an infinite regular set. Conse
A multiple-entry finite automaton (mefa) is a finite automaton where any state can serve as an initial state. The reason for studying such automata is that there is a class of regular sets which can be recognized much more economically with a parallel bank of identical mefa's than with conventional
