There has been a lot of discussion about this. My recollection of the conclusion is that there's no way to protect your macro against a determined programmer in 9.2, when the SECURE macro option is introduced.

The most recent thread was entitled "read only macro code", June 20-21 of this year. This was a short thread (I think everyone was tired of the topic), but Ron Fehd gave a pointer to one of his papers: <http://www2.sas.com/proceedings/sugi30/267-30.pdf >.

You're probably giving this macro to someone who's still running 9.1.3 or earlier, so you're out of luck. Can you put the essential code into a compiled data step?
