How to write using a case statment

[animesh123]

If Cp1=psg and psg-seg= land and cp2 ="" then rank=2 else rank=1

This is Data Step Syntax. The Data Step does not have a Case Statement. Instead, I think you want to write a Select Statement and do something like

select;
   when (Cp1 = psg and psg-seg = land and cp2 = "") rank = 2;
   otherwise rank = 1;
end;

Replace IF with CASE WHEN, clean up the syntax after THEN

case when Cp1=psg and psg-seg= land and cp2 ="" then 2 else 1 end as rank

As pointed out by @PeterClemmensen you can't use this in a DATA step, only in PROC SQL
