Chinese Text Processing System

This Chinese/Kanji text processing system utilizes three subsystems: (1) a data entry subsystem; (2) a text processing subsystem; and (3) an output print subsystem.

The data entry subsystem is used for entering Chinese characters (words) into the system via a keyboard. Chinese characters can be decomposed for keyboard entry in the manner described in IBM Research Report RC5249 entitled "Data Entry of Chinese and Kanji Characters" dated February 4, 1975, by E.F. Yhap. In such publication, 74 keyboard symbols are associated with sets of printing instructions. This number of symbols can be conveniently mapped to a subset of the set of 48 PL/I symbols. For example, the 26 letters of the alphabet and the numbers 0 through 9 (with "0" represented by "Phi") can be used together, with their upper "shift" represented by a $ sign prefix to provide 72 keyboard entry symbols. Also, two additional symbols such as "," and "." are used.

The text processing subsystem internally processes representations in of the Chinese words (characters). Using a mapping such as that employed on the data entry subsystem, any Chinese word will be representable in the system as a sequence of PL/I symbols. For example:

The character (word) representation is then entered as the following sequence of PL/I symbols: J$MO.

With a PL/I compiler provided in the text processing subsystem, the user can then write any program he wishes to manipulate, e.g., sor...
