  • Computer display with two-part cursor for indicating loci of operation
    Patent number: 4806916
    Abstract: A system for creating and modifying strings of symbols in a computer storage apparatus includes a two-part cursor for guiding the operator. One cursor part indicates the exact location where entered symbols will be inserted. A second cursor part highlights a selected substring which is the object of certain commands, such as the delete command. Internally, the system provides memory management techniques for inserting and deleting symbols in response to operator commands. The display, including the two-part cursor, is derived from the memory contents with the aid of pointers, tables, and state variables.
