    Three instruction is all that are needed.
    (1): { INC ( r ), DEC ( r ), JZ ( r,z ) }, i.e.

        { INCrement contents of register #r; DECrement contents of
        register #r; IF contents of #r=Zero THEN Jump-to Instruction #z}

    OR


    (2): { CLR ( r ); INC ( r ); JE ( r_i , r_j , z ) }, i.e.

        { CLeaR contents of register r; INCrement contents of r; compare
        contents of r_i to r_j and if Equal then Jump to instruction z}


Equivalent to a Turning machine.
