In order to improve the operation of softwares programmed by N88BASIC language, an attempt to introduce mouse-subroutines for the whole operations into the program was made. MSGRAPH.BAS thus programmed as a demonstration software is useful for graphic drawing, and also various mouse-subroutines included in this program would be cut out and utilized for the development of chemical softwares.
Key words: Graphic software, Mouse subroutine, Visual operation, Pull-down menu, N88BASIC
