The planistofirstreadtheexecutablefile,disassembletheinstructionsandanalys e them to recover the information that was lost after compilation but is needed to latermodify and recreatethe program. Thenvarious transformations of the program’sinstructions areattempted. Finally a new executablefile is written. This work consists of two parts. Firstly to identify the problems involved, particularly with the code analyser, which is the complicated part of the sys- tem. Secondlytoimplement asystem performing the describedprocedure. The results are that no problems preventing a successful analysis has been found, provided the original programis reasonably well behaved. The imple- mentation has been completed so far that a few very simple programs can be modified. Thereasonfornothavingcompletedtheactualsystemisthelimited time availablefor amaster’s thesis.
