1. A process for controlling graphic user interface software and accessing data files in a computer system, comprising the steps of:

  • reading a code symbol using an optical image reading device to create a read-in code, said read-in code comprising an alphanumeric code in at least base 32;

    storing the alphanumeric code in a temporary buffer memory;

    polling the buffer at periodic intervals to determine whether an alphanumeric code is stored therein;

    testing the alphanumeric code using a validation protocol to assure that the stored code is complete;

    translating the alphanumeric code into a base 10 code, said base 10 code comprising an object identification;

    comparing the object identification with an object table to determine if the object identification is a control code for the graphic user interface software or a document request code; and

    if the object identification is a control code, then implementing the following steps;

    matching the base 10 control code to a corresponding internal event identification code, andcomposing a message from said internal event identification code for detection in a main event loop of the graphic user interface software whereby said graphic user interface software interprets and executes the message to control user interface functions; and

    if the object identification is a document request code, then implementing the following steps;

    composing a search query using said object identification for execution by a search engine residing in said computer system, and executing said search query to locate and display the requested document on an output device.
