Abstract
PURPOSE:To realize the execution of a word and a link processing between the words and to eliminate link overhead between the words, by providing an interpretive pointer stack and a microinstruction mask. CONSTITUTION:A FORTH machine 2 is backend machine for a host computer 1, and it is constituted so that the dictionary of a FORTH word can be formed in a WCS12 and it can be made access from the host computer 1. The address of the word to be executed is supplied from the host computer 1, and an execution result is delivered to the host computer 1. A microinstruction read out from the WCS12 to a microinstruction register 13 by a sequencer 11 supplies a control signal to every part passing a decoder 14. The interpretive pointer stack 16 is used for the designation of a word address.
