如何找出dummy values?

shiyiming

data a;
input x@@;
cards;
2 33333 45 77 18 99
;
run;
在 data a里,x有重复出现的值(只要重复出现且只有唯一的数字)，比如33333,77,999，请教怎么能找出他们,并标注出来(ind=1).
x ind
2 0
33333 1
45 0
77 1
18 0
999 1

谢谢!!!

[code:3jl182ky]data have;
set a; drop xc;
ind =0; xc =cats(x);
if x >=11 then if xc =repeat(first(xc), length(xc)-1) then ind =1;
run;[/code:3jl182ky]
