Abstract: PURPOSE: To resolve problems apt to bring about confusion or case grammar by determining whether a mojority of characters in a word is numeric or alphabetic characters and determining whether a majority of alphabets is upper-case or lower-case in the case of alphabetic characters and determining whether characters should be changed to similar prototype characters in accordance with the case class of the majority. CONSTITUTION: In a block 20, it is determined whether a character is in the case class of alphabetic characters or the case class of numeric characters, and it is determined whether the character is in the case class of upper-case characters or the case class of lower-case characters. With respect to the whole of an output word, the number of members free from confusion of cases in each case class is counted, and a case is determined in accordance with majority of numbers of members free from confusion of cases. Thereafter, case grammar is applied if a character of the word is a prototype character apt to bring about confusion of cases, and the character is converted to a corresponding equivalent prototype character in accordance with the case group of the majority. For example, 'z' and '1' of '49zz18' are converted to '2' and '1' respectively.
