ABSTRACT:
A raster scan type display apparatus for displaying characters having attributes. The attributes are, for example: (i) underlining, (ii) reverse video, (iii) high intensity, and (iv) blinking. The characters and attributes are stored in a refresh memmory. The display may be operated in either a field attribute mode or in a character attribute mode. In the field attribute mode, one field attribute byte in the refresh memory sets the attributes for at least one, but usually many characters which follow the field attribute byte in the refresh memory. In the character attribute mode, one character attribute byte in the refresh memory sets the attribute for only one character which precedes the character attribute in the refresh memory. In the character attribute mode, field attributes may be provided (in addition to the character attributes) for strings of characters following the field attributes.
