PURPOSE:To realize the method of alteration enabling for the data input for the item change and having a good memory utilizing efficiency, by rearranging the data by comparing the item of analysis before and after the alteration bit by bit, in altering the items for request of analysis. CONSTITUTION:The memory area 8 for request item registration stores the table of the request item of tested body bit by bit, and taking 1 when request is present, and the head address of the area 9 storing the data corresponding to the item of 1 of each bit in the data registration memory area 9 is stored in the area 8. If there is any alteration for the request item, the number of items before and after the alteration is compared, and if the number of items after alteration is less or equal, the data rearrangement is made in the same area and if the item is deleted, the location of the area 9 is shifted. If the number of items after alteration is much, the data is retransferred to the memory area 10 for correction data registration, performing the rearrangement of data. Thus, the alteration of items can be made at any time without lowering the efficiency of memory utilization. |
