(A) graphic editor for automatic fortran code generation in nuclear power plant process control environment

Abstract

This thesis describes a graphic editor which can be used to edit or modify easily display frames and to generate automatically the Fortran codes. The editor is specifically developed for nuclear power plant process control software production. A user can draw graphic objects or write text by selecting command on the screen. Moreover, display frames already generated can be converted into the equivalent Fortran codes. Also described is the user-interface which is easy to learn and use, and the code generation method which can convert a display frame already generated into Fortran codes. The graphic editor has been programmed in FORTRAN 77 and runs on VAX 11-780/ VMS with TEKRONIX 4113A color graphic terminal at the Korea Advanced Energy Research Institute(KAERI).
