Change your "and" to "or", and it will work as expected.

> %if %scan(&months,&month) ^= mar and &year^=1997 %then %do;

Since both your conditions are negations, the only way for the expression to evaluate to false for Mar 1997 and execute the else is when the 2 conditions are OR'ed. Thus, the expression is always true when the month is not Mar or the year is not 1997.
