Here is one way:

data want;
  set have;
  retain state2;
  if not missing(state) then state2=state;
run;

This should do the trick

data have;
	infile datalines dlm="," missover truncover;
	length state $2 name $6;
	input state $ name $;
	datalines;
NY,Joy
   ,Thomas
   ,Mike
TX,Albert
   ,James
IL,Corey
;
run;

data want(drop=holdstate);
	length state2 $2;
	set have;
	if _n_=1 then do;
		holdstate=state;
		state2=state;
	end;
	else do;
		if state="" then state2=holdstate;
		else do;
			holdstate=state;
			state2=state;
		end;
	end;
	retain holdstate;
run;

Hi art297, Your code just copy the column STATE to STATE2. Would you please verify. Remember that STATE2 variable did not exist in the have database.

Thanks,

Run the code on your data. It does what I think you requested.

No it doesn't.

The code is:

data want;
  set have;
  retain state2;
  if not missing(state) then state2=state;
run;

RETAIN holds the value until it is changed explicitly.

The assignment of State to STATE2 only occurs when there is a new value of STATE. It returns exactly your desired stated output using the simplest methods.

If it isn't doing what you want, you need to provide more details.
