I can't find an example using a DATA step with multiple SET statements.
I need to find previous 12 months observations based off a DATETIME value.
I'm pulling previous month easily by:
MONTH(DATEPART(DATETIME)) = MONTH(TODAY() -1);
I remember running across an example before but cannot find it.

Its quite hard to see what your after from that, test data in the form of a datastep and what you want out will help. Can you not sort the data, then use lag()? SQL can simply merge these too. If its an agregate then a where might be better.
