Rename rows in a column to new names in a new column

[kaufjd01]

Agriculture data set. Need to rename all similar pens 1 and 3 into treatment = A and rename all similar pens 2 and 4 into treatment = B. Treatment would be a new column. How do I setup up this code? It seems like it would be simple, but I am struggling. Thanks!

if PEN in (1,3) then Treatment = 'A';
else if PEN in (2, 4) then Treatment = 'B';

Thanks @Reeza that worked for me! I was missing the 'in' and parantheses.

Best!
