Abstract

PURPOSE:To simplify the prolog processing by securing such a constitution where an integrated access is always possible to a pointer pushed to a local stack with the offset applied to the present environment frame from the pointer (E register). CONSTITUTION:A main memory 1 is provided together with an instruction decoding part 2, a register file 3 and an arithmetic and logic unit ALU4. Then the continuation is applied to a local stack even when a paragraph contains just <=2 goals at a main body part when a paragraph including a cut goal is carried out. Thus an integrated access is always possible to a pointer pushed to the local stack with the offset given from an E register regardless of a fact whether the relevant paragraph contains a permanent variable or not, whether only a temporary variable is secured or not with >=2 pieces of goals of the main body part or whether the number of goals is equal to 2 or less. As a result, the prolog processing is simplified.
