In reply to Prashant.

Thank you, Prashant, for your comment. I am sure R&D will look into your suggestion. There are, however, multiple ways you can encrypt SAS variable values. For example, see this piece of SAS documentation. Another approach could be using PROC PWENCODE and treating each variable value as a password to be encrypted, see this blog post One deadly sin SAS programmers should stop committing. Do any of these appeal to you?
