Six-digit coding method

The Six-Digit Coding Method (SDCM) is a new coding method for Chinese characters. It is based on the structural analysis of Chinese characters. We recently developed this method and have successfully used it to code 11,100 characters, including the simplified, traditional, and variant forms found in Xin Hua Dictionary [7]. This article illustrates the basic principes, features, and some viewpoints concerning the method.

Building bilingual microcomputer systems

In the Arab world the need for bilingual microcomputer systems is ever increasing. In addition to the ability to process the Arabic and English scripts, an ideal system should support the use of existing applications with Arabic data and the access to the system facilities through Arabic interfaces. The Integrated Arabic System (IAS) was developed to study the feasibility of building such systems using existing microcomputers and software solutions.

Typographic style is more than cosmetic

There is disagreement about the role and importance of typographic style (source code formatting and commenting) in program comprehension. Results from experiments and opinions in programming style books are mixed. This article presents principles of typographic style consistent and compatible with the results of program comprehension studies. Four experiments demonstrate that the typographic style principles embodied in the book format significantly aid program comprehension and reduce maintenance effort. —Authors' Abstract
