A processing device receives programming instructions, which may be executable programming code. The processing device, which is within a processing environment, accesses an access table to retrieve the corresponding programming instructions associated with the programming terms in the code. If the instruction, which refers to a particular programming term, is not within the access table, the search is continued within a terms database that includes the user-defined terms. If the term is found within the terms database, that indicates that the programming term is a user-defined term. The corresponding mapped functionality or operation is retrieved and provided to the processing device. The processing device thereupon executes the corresponding program instructions based on the operation mapped from the native term even though the incoming code includes user-defined terms.
