PURPOSE:To accelerate the reference of a variable within a frame on an environment list, by providing a register that designates directly the head address of a real subtracting number group on a stack of the function which is lately called outside a main storage device. CONSTITUTION:For a function type information processor, the real subtracting number is connected to the tentative subtracting number of the functions F2 and F3 to be called by the structure of a program and the style of execution. Then the called function carries out a prescribed procedure with reference to the transferred real subtracting number and a large region variable and then sending the function value back to the calling side to perform a process of information. A register is added to designate directly the head address of the real subtracting number group on a stack of the function which is lately called outside a main storage device. Thus an access time referring to a variable is decreased. The variable stores a list showing the connection among data into a stack memory based on a deep binding system. |
