I think this is just right. However, if the input file is already
sorted by year-age-gender, the SORT CASES is unnecessary: the new total
case will automatically follow the existing cases in the group, as long
as the file with the totals is listed second on the ADD FILES (as you
have it). Syntax manual, for ADD CASES/BY:
"Cases in the resulting file are ordered by the values of the key
variables. All cases from the first file with the first value for the
key variable are first, followed by all cases from the second file with
the same value, followed by all cases from the third file with the same
value, and so forth. These cases are followed by all cases from the
first file with the next value for the key variable, and so on."
