19. A method as set forth in claim 17 which includes the step of updating said stored word address in said first register whenever all of the bits in the second register are shifted to said third register, and transferring the new word represented by the updated address to said second register.
17. A method for executing an interpretable language string and for executing one of a plurality of stored elementary language programs which is represented by a machine level code contained in said interpretable language string, comprising the steps of: a. storing in a first register a word address and a bit address within said word which represents the machine level operation code to be extracted from said interpretable language string; b. storing the word thus identified in a second register; c. shifting bits of the stored word from said second register to a third register and simultaneously incrementing said bit address in said first register; d. outputting the machine level operation code from said third register when a predetermined shift of said bits has occurred; e. locating the stored elementary language program which is represented by the extracted machine level code; f. extracting an elementary language operation code from said elementary language program as located; g. decoding the extracted elementary language operation code; and h. executing the elementary operation which is represented by the elementary language operation code.
