Abstract
Systems and methods are disclosed for preparing program code for a first computer, wherein the systems and methods are implemented on a second computer. The systems include a relocating module that is adapted to relocate program code by modifying locations in the program code identified by location data. The modifications made by the relocating module are based on a memory address. The systems operate on program code for the first computer, where the program code is stored on the second computer. The relocating module is provided the memory address that identifies a memory location in the first computer. The memory address is suitable as a basis for modifying the program code. The relocating module is also provided with location data that identifies locations in the program code to be adjusted based on the memory address. A method practiced in accordance with the disclosed embodiments includes the steps of obtaining the program code; obtaining the memory address; obtaining the location data; and modifying the locations in the program code identified by the location data, by using the memory address and by using the location data, where the modifying step is accomplished at the seco…
