Abstract

A method and system for reducing transmitted code for remote application forms. First code to link one or more functions to a remote application is received at a client digital processing system (DPS). Each function contains instruction code to generate object construction code and a set of object parameters. The object construction code is used to create a corresponding object. The one or more functions are linked to the remote application form. Second code is received to call one or more of the functions. One or more of the functions is called to construct one or more objects at the client DPS. The constructed one or more objects is presented as part of the remote application form based upon the object parameters.
