Scramble / Encrypt Igor code

Good morning, 

Is it possible to encrypt or scramble Igor procedures? They still have to be functional but not visible as plain text. 

I have a quite delicate experimental setup which I controll via Igor. Scince there are a lot of students working on the setup I would like to make changing the code a little bit more difficult. Recently I had a well meaning student who changed a controll procedure and thereby frying a laser LED. 

Best regards,

How about just hiding them ...

To see how execute in the command line:
