PURPOSE:To realize the high speed retrieval of data arranged sequentially by providing a data memory consisting of numerical-ordered memory units and a retrieval table, a number searching means and an address searching means. CONSTITUTION:When a user inputs the line number of a statement and the statement from an input/output part 3, a CPU 2 stores them in a text memory 4 in order of the line number. Next, the CPU 2 generates the retrieval table 6. When a head address in which the statement of the line number A is stored is retrieved, the CPU 2, at first, sets the head number of the table 6 in a retrieving pointer Q7. Next, it increases the contents of the pointer Q7. Next, is sets the contents stored in the table unit of the number stored by the pointer Q7 in the pointer P5. Next, it reads the line number stored in the memory unit of the address stored in the pointer P5, and decides whether the read line number is 'behind' the line number A of an object to be retrieved or 'not'.
