Array Token Petri Net Structure (ATPNS) to generate rectangular arrays has been defined in [6]. We prove that this model generate the regular array languages. By introducing a control on the firing sequence, we have shown that, ATPNS with inhibitor arcs generate the context-free and context-sensitive array languages. Comparisons with other classes of array languages have been made.
