Abstract: For a Prolog processor, a plurality of table entries are formed in a predetermined number of formats for storage in a program memory (21). Each table entry has a preselected number of fields which are related to the fields of at least one other table entry so that the table entries represent a Prolog program. A plurality of registers (26-28) are for storing, from time to time, various fields of the table entry read out of the program memory. Responsive to the fields of the read-out table entry, a control unit (25) controls a selector (22) for selecting one of the registers at a time to make the field stored in the selected register access the program memory for read out of another of the table entries.
