Default if vs else if vs else

Is there a logic for when to use if vs else if vs else ?

I'm creating a new variable in a data step based on another variable I all ready have. I feel like you should end with else, which is like saying, "if none of the above criteria matched, just do whatever the else tells you to do."

I also imagine, you have to begin with an if, otherwise beginning with an else if doesn't make logical sense. It probably doesn't make syntax sense, but if I understood this situation, I would not be posting here for help.

when after your first "if" do you use "if" or "if else" or "else"

Cheers,

Gareth Keenan
