Abstract

The disclosed method for converting some Japanese Business/Personal Computer (JPC) data sets into and from documents that can be processed by a Japanese Word Processor (JWP) on a small system takes into account the differing data stream representations to provide a conversion that is as faithful as possible. In particular, Japanese characters in both JPC and JWP may be printed with different character sizes. All characters are translated so that no information is lost and so that the output resembles the input as far as possible, even though the data stream of JPC does not support differing character sizes in the same manner as the JWP data stream.

Supporting Multiple Character Sizes During Data Set Translation

The disclosed method for converting some Japanese Business/Personal Computer (JPC) data sets into and from documents that can be processed by a Japanese Word Processor (JWP) on a small system takes into account the differing data stream representations to provide a conversion that is as faithful as possible. In particular, Japanese characters in both JPC and JWP may be printed with different character sizes. All characters are translated so that no information is lost and so that the output resembles the input as far as possible, even though the data stream of JPC does not support differing character sizes in the same manner as the JWP data stream. Furthermore, controls governing character size in the resulting data set or document are inserted only where absolutely necessary due to actual changes in character size in the initial document or data set. A Japanese small business computer/personal computer may support several applications tailored to the particular user set. Business computer applications require a general-purpose system which is very flexible and which may be used under a large variety of situations. Users are often familiar with computer systems and programming concepts. JPC data sets, in particular, are designed to be able to support a very large variety of business or personal applications. This means that the data set and data stream architectures should be very simple and extendable to many applications. Word processing applications present special perfomance and function requirements. To provide optimum function for a word processing user, the system and application programming may be tailored specifically to the unique JWP requirements. Data set and data stream architectures, in particular, may be very complex and designed specifically for JWP needs. Word processing operators as a class tend to be less sophisticated in their knowledge of computer concepts than general JPC users. This is not necessarily a disadvantage, since the JWP applications generally perform all functions associated with data streams and data set architectures. The JWP operator thus does not know at all about the complexity of the underlying structures of a document. The Japanese written language consists of many thousands of ideographic characters (Kanji). Due to the complexity of the characters, so that readers may recognize them easily, each one needs more space on a page than would normally be true of Latin- based characters. For consistency, all characters, even the Latin-based alphanumeric and the Japanese phonetic characters, are represented in a character set where all characters occupy the same amount of space on the printed and displayed text. However, for information compaction, there exists a second representation of the Latin-based alphanumeric characters and some Japanese characters, so that the character takes up only half as much space on the display and print...
