Patent ID: 7587519

Claim:
A method for modifying messages transmittable via an electronic message transmission system by an electronic arithmetic device, said method comprising: reading in a message having a hierarchical modular structure including a plurality of structural units; determining the hierarchical modular structure of the message; selecting an individual structural unit of the plurality of structural units of the message; determining one or more feasible modifications of the selected individual structural unit, wherein feasibility of the one or more feasible modifications is based upon a structural unit type of the selected individual structural unit without regard to the hierarchical modular structure of the message; displaying the one or more feasible modifications; reading in a selected modification of the one or more feasible modifications; determining validity of the selected modification, wherein the selected modification is determined to be valid if the selected modification would not change the hierarchical modular structure of the message; implementing the selected modification if the selected modification is determined to be valid; and issuing a modified, new message.
