Abstract

PURPOSE:To prevent the runaway of a program, by making only contents, which are indicated as addresses by an indicating means of subroutine return time effective in the program controlling system for an information processing device having an address stack. CONSTITUTION:Each entry ENT in a stacker STK is provided with an address/ data discriminating flag F as a means which indicates whether an address or data is stored in this entry ENT; and when a subroutine return instruction is generated, this flag F is referred to reset the value of a stack pointer SP to an entry n-1 of F=0, and thus, an address (a) is read out surely.
