ABSTRACT:
A data processing apparatus includes a plurality of function keys and character input keys, a display for displaying inputted data; and card data group storage device for storing a plurality of card data including numerical data. The card data has a capacity capable of displaying one picture of the display device at one time and can be grouped with other card data through a link data. A card data group specified by the activated keys is read from the card data group storage devices. The numerical data contained in the card data of the selected card data group is processed by various calculations inputted by the function keys. This apparatus further includes a judging/readout circuit for reading out other card data groups associated with the previously readout card data group from the card data group storage device when a judgement concerning the link data attached to each of the card data groups is made. These same calculations can be carried out on the numerical data of other card data in other card data groups judged to have a connection with the initially read card data group after calculating the numerical data contained in the card data of the first card data group.
