You didn't had a look at the log, eh ? Else you would have seen that SAS does not know about first.longdata. You have to use a BY statement !

SET INLD7.ALL; BY longdata; if (first.longdata and last.longdata) then output nodups; else output dups;

> proc sort data = inld7.all; by longdata; run; > data INLD7.dups INLD7.nodups ; SET INLD7.ALL; > if first.longdata then > output INLD7.nodups; > else > output INLD7.dups; > run; > >
