Dear SAS-L-ers,

Ya, interesting question and nice ensuing discussion!  However, as several posters have concluded, it does not seem likely that you can shield the SAS code from being modified by a determined individual and always tell when s/he has modified it in Display Manager.

But, maybe that is why they invented SAS/IntrNet:-)  As you likely know, SAS/IntrNet makes use of carefully-crafted web pages on the front-end that fire off canned SAS programs on the back end.  Users click on selection lists, check boxes, radio buttons, etc. to specify their data selection/processing criteria.  The Name/Value pairs in the web pages are passed to the SAS/IntrNet programs on the backend and become Macro variables that the programs then use to create the reports.  So, the users simply cannot get their grubby little paws on the SAS programs and slyly modify them to suite their nefarious schemes.  The programs totally are shielded from the users.

So, you might consider a SAS/IntrNet solution... if time and money and resources allow it.

Ya, best of luck in all your SAS endeavors!

I hope that this suggestion proves helpful now, and in the future!
