An electronic route translation system arranged to translate a first combination of 3, 4, or 6 numerical digits to a second predetermined combination of 3 numerical digits. The translator selectively reads segments of word information directly from memory into one output register without using additional adding, subtracting, shifting or masking functions. The read feature permits the same address in memory to be interrogated several times in a single translation with different segments of the same word being used each time. Internal manipulations are accomplished by data substitution in the address field. The input digits are employed without conversion to form the first translation table address and subsequent addresses are formed by a combination of the input digits and control data obtained from interrogation of the memory. A check is applied to each registered digit after every register transfer, thereby providing an extremely well-defined error stop function.
