Here is the list of Brenda Speer's notes that you will need.
A method of inserting additional characters within an existing series of characters on a display, comprising:
(a) providing a memory that is able to store a series of characters at an adjacent series of addresses in said memory
(b) providing a character input means that a human operator can use to store a series of characters in said memory at said respective adjacent series of addresses
(c) storing said series of characters in said memory at said adjacent series of addresses
(d) providing a display that is operatively connected to said memory for displaying said series of characters stored in said memory at said adjacent series of addresses
(e) providing a pointer means that said operator can manipulate to point to any location between any adjacent characters within said series of characters displayed on said display, and
(f) providing a memory controller that will
(1) direct any additional character that said operator enters via said character input means to a location in said memory, beginning at an address corresponding to the location between said adjacent characters as displayed on said display, and
(2) cause all characters in said series of characters that are stored in said memory at addresses subsequent said location in said memory to be transferred to subsequent addresses in said memory so that said additional character will be stored in said memory at said location and before all of said subsequent characters,
whereby said display will display said additional character within said series of characters at said location between said adjacent characters, and
whereby a writer can add words within existing body of text and the added words are displayed in an orderly and clean fashion without having to reenter said existing body of text.
