1. A method to retrieve data using a single input class operating in three or more modes, the input class being part of an interpretative based application running on an information processing unit, the method comprising the steps of:

  • executing an interpretative based application on an Interpretative Machine (IM) with an input class function containing at least one parameter string for passing data to the application;

    determining which of a plurality of modes the application requesting input from the input class function is running, the plurality of modes including;

    a live mode, wherein the database is available either locally or through a network;

    a demonstration mode, wherein the database is not available;

    or a setup mode, wherein the database is available either locally or through a network;

    wherein when the application is running in the live mode, the input class function performing the steps of;

    using the parameter string to create a pointer into the database; and

    retrieving the data from the database using the pointer to the database;

    wherein when the application is running in the setup mode, the input class function performing the steps of;

    using the parameter string to create a pointer into the database;

    retrieving the data from the database using the pointer to the database; and

    creating a copy of the data retrieve from the database into a file on the information processing system with a file name based on the parameter string;

    wherein when the application is running in the demo mode, the input class function performing the steps of;

    using the parameter string as the name of the file to retrieve data locally stored in a file on the information processing system during setup mode; and

    retrieving the data using the parameter string;

    wherein when the application is running in an environment where the IM is coupled to a web browser or the application is running in an environment where the IM not coupled to a web browser, no changes to the application making the call to the input class is necessary to retrieve data.
