1. A method for automatically modifying computer program logic with respect to a selected data type, comprising the steps of: (a) analyzing object code representing computer program logic from the computer program to identify references to the selected data type, substantially without reference to or reconstruction of source code, wherein the object code representing computer program logic is analyzed by one or more processes selected from the group consisting of: disassembly, further comprising the step of applying inferential analysis and state dependent analysis to the disassembled object code representing computer program logic, scanning data files referenced by the object code representing computer program logic to locate data formatted as date data, and tracing presumed references to the selected data type through a logical flow of the computer program logic; (b) modifying the computer program logic with respect to the selected data type to alter computer program logical execution with respect thereto; and (c) storing information representing the modified computer program logic for execution.
