Actually, the y==5 part would be a nice way of simplifying the coding and avoiding errors in this case. However, suppose instead that you couldn't count on Y equaling 5, e.g. suppose the first statement was more like gen y=x12, and you couldn't count on x12 not equaling a value that would also be assigned via a replace statement. Then, you'd have to use a more complicated syntax like I had before.First point is to analyse the logic. Reforming a problem often speeds up the execution far more than fancy coding, and leads to insights. In this case: gen y=5 replace y=3 if x1==1 & x2==3 replace y=4 if y==5 & (x3==2 & x4==17)
