A message interface generator is disclosed that generates code routines that convert data elements between proprietary binary formats of one or more computer systems and a portable machine and software generation system independent message format, referred to herein as the "independent message format." Thus, two systems can communicate data using the uniform independent message format, notwithstanding the proprietary binary formats of either system. The message interface generator automatically generates conversion code from existing data definitions to permit two systems to communicate using the uniform independent message format. The conversion code converts data elements of a given data type to and from the proprietary binary format of each system and the independent message format used on the common communication channel. The independent message format includes a predefined (but arbitrary) standard for each data type to be communicated between the two systems. A data element is transferred between two systems using the independent message format by providing a message indicator header file containing a message description directive and a reference to the header file defining the data element. The message description directive indicates that conversion code should be generated for the indicated data element. The message interface generator includes a tool that analyzes an input file for one or more predefined (but arbitrary) keywords, such as the "message" keyword, to initiate generation of the conversion code for each desired data element.
