摘要

A method for coding the input of Chinese characters from a keyboard according to the first phonetic symbols and tones thereof includes the steps of making a dictionary; establishing a conversion table which converts each of Chinese phonetic symbols to an approximate English letter in accordance with the phonetic similarities therebetween; establishing coding rules for coding the Chinese characters in accordance with the first phonetic symbols and tones thereof; setting a mode selection symbol as the first symbol of the instruction codes for the English letter mode, the mode selection symbol being an English letter which is not present in the conversion table; and making an ASCII code keyboard which has a plurality of English alphabet keys, some of the English alphabet keys being respectively marked with a corresponding Chinese phonetic symbol according to the conversion table. The dictionary has an instruction code index section and an input/output conversion section.
