PROLOGUE LANGUAGE COMPILE PROCESSING SYSTEM

摘要

PURPOSE:To execute the processing at a high speed by constituting the titled system so as, for a predicate called from other object, argument number information is generated and held in its own object, and for a predicate for calling a predicate of other object, an executing instruction can be selected by referring to its information. CONSTITUTION:In objects 1b, 2b which have been generated by dividing and compiling independently programs 1a, 2a by a modularizing function, an address of an instruction to be executed in the next time, when a tag of an argument register is a variable, a constant, a structure body and a list is held in each of the first, the second, the third and the fourth elements of a tag indexing table 2b-10, respectively. Also, in the final element of its table, a register number for executing the indexing is generated and held, the register is checked by using the final element of the table 2b being in an address which has been indicated by an operand of the object 1b, and in accordance with a kind of its tag, an address of an instruction to be executed in the next time is detected and set to a program counter.
