Sure the idl code can be recovered, just like you can disassemble any
executable file. You won't recover the variables names but you can see the
logic of the code. The question is more whether its worth the effort. I
would be curious in seeing how it's done but asking myself whether I would
waste my time on it, the answer is absolutely NO. What's the sense? Even the
ENVI routines are in the end just implementations of publicly available
algorithms.
