Zusammenfassung:A data processor in which the address fields within the instructions may be of two different lengths in terms of the number of address digits in the field. The number of digits in the address field is determined by the digit in the most significant digit position of the address.

If the most significant digit is not coded to be the special character but a decimal digit, it is used together with the next four digits as the address.
