ok i just thought of something , this will probly get me burned but hay...
say im a virus writer and i want to insert my code onto the end of a file called "sheep.exe" (being original here) would it be as easy as, making, with Basic, the code i want to copy and saving it as "virus.exe" (being original again) then simply renaming 'sheep.exe' to 'sheep.TXT'
(spot the difference and the ren 'virus.exe' to 'virus.txt' and copying the contence of a to the bottom of be and renaming the now moddifyed 'sheep.txt back to a .exe extencion, would it still work, and would the existing code form 'virus.exe' still be intact???
