PURPOSE:To improve the quality of calculated results by impressing a sientific and technical programming language capable of handling a four-dimensional numeric on a compiler capable of analyzing. CONSTITUTION:A source program 1 including newly expressed source program language 1a is inputted to a compiler 2. A vocabulary analysis part 3, a syntax analysis part 4 and a processing part 5 for giving meaning in the compiler 2 are equipped with corresponding processing means 3a-5a. What the vocabulary analysis part 3 hands in to the syntax analysis part 4 in the compiler 2 is a token string, and what the syntax analysis part 4 does to the processing part 5 for giving meaning is an analysis tree. The corresponding processing means 3a-5a sequentially process the source program. As a result, the programming language can be easily produced and the time required for compiling can be shortened.
