Appendix A: Backward Compatibility
ALK Technologies does support backward compatibility with previous versions
of PC*MILER and PC*MILER for the AS/400. However, it is not advisable to
develop new applications that use these short city name structures, because you
lose access to county information which is necessary for resolving duplicate city
name problems. Over time, this backward compatibility becomes increasingly
difficult for ALK Technologies to maintain. Future backward compatibility is not
guaranteed.
If you would like more information about backward compatible formats, please
contact the ALK technical support staff (see Chapter 11).
