Abstract

This article describes a code conversion scheme in a display terminal in which EBCDIC character codes are converted to display character codes stored in a display buffer for addressing a font generator, and vice versa, wherein the EBCDIC codes are classified into three groups. The EBCDIC codes of the first group are assigned to characters commonly used in all countries to which the display terminal is shipped, the EBIDIC codes of the second group are assigned to characters commonly used in some countries but not used in the remaining countries, and the EBCDIC codes of the third group are assigned to characters which are unique for each country. Fig. 1 shows one example of the assignment of the display character codes to the EBCDIC character codes in four countries.
