Disclosed is a system, method, and program for translating source code statements to executable code. A source code statement including an application program interface (API) that is a member of a set of standard APIs calling an object in a first format is processed. A mapping is used to determine at least one user interface API corresponding to the determined standard API. The user interface API provides an implementation of the standard APIs in a user interface program. A mapping is determined of the called object to a corresponding object in a second format utilized by the user interface program is accessed. The source code statement comprising the standard API calling the object in the first format is converted to the determined user interface API calling the corresponding object in the second format. The user interface program is capable of executing the user interface API calling the corresponding object.
