Developing Compiler for Nihongo Programming Language PEN

When a novice programmer starts learning computer programming, C or Java are often employed. They are general purpose and useful languages, but for Japanese novice programmers these programming languages are difficult. One reason for this difficulty is English keywords employed in these programming languages; that is, these words are not in Japanese learner's native language. Recently, for Japanese novice programmers, "Nihongo-based" programming languages have been developed in Japan. PEN is a Nihongo-based programming language for education. A programming environment has been developed for PEN, and the environment has an interpreter. However, there has not been developed a compiler for PEN. In this paper, we aim to develop a compiler for PEN language; actually, we develop a translator from PEN into C, and we finally obtain a binary code with a C compiler such as gcc.
