I have the following dataset
data have;
input profit;
datalines;
52
34
60
57
70
;
run;
I want to write a program that will create a new dataset, only containing the difference between the first and last observation?
In this case the code would show 70 (last observation) - 52 (first observation), so the output would be 18.
Here is one way:
data want; set have end=last; retain first; if _n_ eq 1 then first=profit; if last then do; result=profit-first; output; end; run;

hi,
data want(drop=_profit);
set have(firstobs=min);
set have(rename=(profit=_profit)) nobs=_nobs_ point=_nobs_;
d=_profit-profit;
output;
stop;
run;
