A method of dynamically providing a host information about all functions supported by a communication platform provided in a computing network environment is presented. The computing network environment is also provided with a gateway device that is electronically connected at least to one initiating host and at least one receiving host, besides the associated communication platform. During an initialization step all functions commercially available on all communication platforms are inputted in a special function table. Then the particular associated platform is queried and the functions provided in the computing environment is determined and inputted also in the function table. All alterations and modifications to the availability of old functions or addition of new functions are also monitored and inputted in the table. In this manner any host connected to the gateway device can obtain a list of all available functions supported by the communication platform at any one time and if desired, even any such host can chose a function from this list of available functions.
