Hi,
I am think that the difference between the first and last
records value?
data _null_;
set abc end=last;
retain first;
if _n_=1 then first=avg;
if last=1 then do;
diff=first - avg;
put 'The difference is =' diff;
stop;
end;
run;
here _n_=1 is hold the first record in the abc dataset.
Last=1 means is hold the last record in the dataset.
