Data processing device for processing a combination of data items.

摘要

In a data processing device for processing a preset procedure with respect to one data item or two data items shown on a display means (e.g. liquid crystal display, cathode ray tube or printed paper), the designating operation of the one data item and that of the two data items are made common and simplified. When a pointer points one of the data elements of a data item, the data item is designated. When the pointer points between two data items, a combination of the two data items before and after the pointer is designated.
