In order to hand my idl routines to other research groups, I would like to not give away my source code but only binaries of my routines. Now, sav files look like the way to go. My only concern is whether the restoring of such sav files might give access in some obscure way to the source code of my routines, ie does the restore command enable a gifted IDL user to perform a decompilation of the binaries? Or am I perfectly safe by handing over sav file routines (ie not give away the ideas and work in my source code)?
Thanks for your answers.

(This does not mean I distrust your word nor is it meant to discredit your expertise in any way, I just want to be double-sure about this).
Hi breme (?),
This is Chris Torrence, Technical Lead for IDL at Exelis VIS. I can confirm what the other poster said. IDL *code* Save files are encrypted with a proprietary algorithm that prevents the de-coding of the compiled code. (Data save files are not encrypted.) If you compile your code and save it to an IDL save file, there should be no way for a user to decrypt the contents and recover your code. This encryption was added in IDL 6.1 (2004) so as long as you create your save files with a more recent IDL version, you can ensure that it is safe.
Cheers,
Chris

Thanks skymaxwell and Chris Torrence. I guess that fully answers my questions and leaves no more room for any concern. Cheers ;)
