Abstract
A character display arrangement for displaying on a CRT rows of discrete characters. Digital codes represent both character data which identifies character shape and attribute data which identifies the attributes to be applied to displayed characters. The attribute data as received and stored in a display memory is in stack-coded form and relates to serial non-spacing attributes. The attribute and character data is read out from the memory one character row at a time. The character data is fed directly to a row buffer which has a position for each character position. The stack-coded attribute data is fed one group at a time to a pertaining fill register where it is decoded into explicit attribute data and fed to the row buffer to be associated with the character data. Once an attribute is set at a given position, it remains pertaining in the pertaining fill register and is fed into each succeeding character position until either a contradictory attribute is set at a subsequent character position in the character row or until the end of the character row.
