Hello,
I want to populate var2 with subsequent record value if the var1 is missing.
data test;
input var1 $ ;
cards;
.
abc
;
run;
data want;
set test;
var2=substr(var1,1,1);
run;
Desired output:
var1 var2
. a
abc a
Merge the dataset with itself, but start one observation later:
data want;
merge
test
test (firstobs=2 rename=(var1=var1x))
;
if var1 = ' '
then var2 = substr(var1x,1,1);
else var2 = substr(var1,1,1);
drop var1x;
run;
