We can use rollup to convert whole data in vector and later use vector data in normalize to assign last column.

rollup: use accumulation function on all columns

NORMALIZE:

length :: 3;

out::normalize(in,index)=
begin
out.name :: in.name[index];
out.city :: in.city[index];
out.startyear :: in.startyear[index];
out.endyear :: if(index==2) 9999 else in.startyear[index+1];
end;
