Abstract: The present invention provides a dynamic interface between two dissimilar software programs that must communicate with each, whether running on one or a plurality of computers. The invention can provide bi-directional, non-intrusive data manipulation and communications between software programs on a distributed computing platform or across platforms on a distributed network. The invention includes user-defined template files, a user-defined equality file, first and second blocks of shared memory, a master interface, and a slave interface. The template files define the output and input data of their respective programs and map the output and input data to blocks of memory. The equality file equates the input data and output data of one program with the output data and input data, respectively, of the other computer program.
