Linked list data encoding method and control apparatus for a visual display

Visual display apparatus comprising:

• a memory having data and control characters;
• a holding register coupled to the memory to receive data and control characters;
• data decoding means coupled to receive a control character representing a link operation from the holding register for producing a link signal;
• control means coupled to receive the link signal from the data decoding means for altering the addressing of a next character to be fetched from memory in response to the link signal;
• and
• display means coupled to the holding register for displaying characters corresponding to said data characters.

Visual display apparatus comprising:

• a memory having data and control characters;
• a holding register coupled to the memory to receive data and control characters;
• data decoding means coupled to receive a control character representing the end of a line of data figures to be displayed from the holding register for producing an end of line signal;
• logic means coupled to receive the end of line signal from the data decoding means for inhibiting the fetching of characters from the memory and loading a selected data character onto the holding register in response to the end of line signal;
• and
• display means coupled to receive data characters from the holding register for displaying visual images corresponding to said data characters.

Visual display apparatus comprising:

• a memory having data and control characters;
• a holding register coupled to the memory to receive data and control characters;
• data decoding means coupled to receive a control character representing the end of a displayable page from the holding register for producing an end of page signal;
• control means coupled to receive the end of page signal from the data decoding means for altering the address of a next character to be fetched from memory in response to the end of page signal;
• and
• display means coupled to receive data characters from the holding register for producing images corresponding to said data characters.

Visual display apparatus comprising:

• a memory having data and control characters;
• a holding register coupled to the memory to receive data and control characters;
