The interpreter is added before the begining of the code in a bound
exe.
Try this:

atom fn
fn = open("patch.exe","ab")
puts(fn,#0A & #AC & "(1,\"tacked on the end!\\n\")")
close(fn)

It probably would be possible to replace the code between 2 string
markers with more shrouded code, maybe this would allow you to patch
the program...
