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;
