Abstract(in English)	It has been our purpose to provide the two-dimensional turtle graphics language by using the regular expressions for the interactive CAI system MACAI. The turtle graphics language SLanG (S__-cientific __-guage for G__-eometry) can draw geometrical figures for the coordinate system and the non-coordinate system. The SLanG which we have developed on the WINDOWS system is able to change the turtle moving speed, paint the designated region, and draw the regular polygons and ellipse which couldn't be drawn by conventional graphical applications. The SLanG would have a strong support for mathematical CAI systems.
