A stack oriented memory system for a computer is provided with a plurality of top of the stack registers. The top elements of a logical stack of information are stored in the stack registers and the remaining information is stored in core memory. An embodiment of a bookkeeping scheme for keeping track of the order of the information in the stack registers comprises two additional registers. A first register stores the number of stack registers filled with stack information. A second register stores a number representing a naming state which defines the logical order of the stack registers. There is also a third register for storing the location of the top piece of information in the stack in core memory. These three registers store the necessary information to keep track of the order of the information in and the size of the logical stack. These registers also facilitate the bookkeeping when information is added to or deleted from the stack registers.
