The class RCM presents some interesting closure properties, and contains languages with holonomic generating functions. As a matter of fact, RCM is related to one-way 1-reversal bounded k-counter machines and also to Parikh automata on letters. Indeed, RCM is contained in LNFCM but not in LDFCM, and strictly includes LLPA. We conjecture that LDFCM⊂RCM.},
