component with only one variable.
1.Input_file
2.Sort with in group (dno asc,sal desc)
3.scan
###############################################
type temporary_type=record
integer(4) temp1;end;
temp :: initialize(in) =
begin
temp.temp1::0;
end;
out :: scan(temp, in) =
begin
out.temp1 :: temp.temp1 + 1;
end;
out :: finalize(temp, in) =
begin
out.sal:: in.sal;
out.dno :: in.dno;
out.temp1 :: temp.temp1;
end;
out :: output_select(out) =
begin
out::out.temp1 == 2;
end;
