I would like to populate the last record of a variable as a new variable
Input
Sno Closing Price
1 10
2 10.5
3 10.2
4 10.4
5 10.6
Output:
Sno Closing Price New_Closing Price
1 10 10.6
2 10.5 10.6
3 10.2 10.6
4 10.4 10.6
5 10.6 10.6
I would like to obtain this output using both a datastep as well as a proc sql if possible.
Thank you much in advance.
Here is one way,
data have;
input Sno Closing_Price;
cards;
1 10
2 10.5
3 10.2
4 10.4
5 10.6
;
run;
data want;
if _n_=1 then
set have (rename=closing_price=new_closing keep=Closing_Price) nobs=nobs point=nobs;
set have;
run;
