Abstract

PURPOSE:To omit the memory accesses such as a local stack, a trail stack, etc., by resetting a variable connected to the specific value as the back track processing to an unconnected state in a predicate logical language, etc. CONSTITUTION:A connected variable counter 11 counts the number of variables changed to a connected state from an unconnected state and stores the number of connected variables counted when the processing is traced at the back track time. A connected variable number associative memory 12 uses the address of a variable stored in a local stack or another memory area as a key and stores the value of a return occurrence counter 10 and the value of the counter 11 when said variable is turned into a connected state from an unconnected state. A return state register 13a stores the value of the counter 10 which is counted up when a back track occurs as well as the number of connected variables counted when the state of the variable is reset to the unconnected state on a back track. The different registers are used for each occurrence of a back track.
