In a distributed application program system which includes a data transmission line, a plurality of server systems connected to the data transmission line and each including at least one application program for executing data processing by running the program, and a client system connected to the data transmission line and including at least one application program for executing data processing by running the application program, a method of controlling the distributed application program system is performed. The method includes the steps of preparing a library for storing system specifications of the individual systems in association with one of the plural server systems which is to serve as a master server system, and deciding whether or not a table provided in association with the client system already contains system specifications of the server system to which data processing is to be entrusted. Unless the table holds the system specifications, the client system requests sending of the system specifications and stores the system specifications received from the master server system. Thereafter, the client system converts the data so as to have a format which conforms with the system specifications stored in the table.
