BINDING FORTRAN LAYERED EARTH MODELING ROUTINES WITH WINDOWS GRAPHICAL USER-INTERFACE

The paper presents a straightforward approach to using existing FORTRA N code within the Microsoft Windows environment. The approach requires little or no understanding of the internal complexities of the Window s operating system and of the C or C++ languages usually used to write Windows applications. The method makes use of the dynamic link librar y (DLL) principle introduced in Microsoft Windows. A simple demonstrat ion in resistivity modeling showing the application of the DLL approac h also is given.
