Have you looked at using PROC MEANS with a BY statement.

In addition to Scott's suggestion for PROC MEANS, you could also use PROC TABULATE.

One other item to take care of --- since RPTDT is a date field, you will want to use a FORMAT to restrict the RPTDT to YEAR level only (not use RPTDT down to the DAY level).

Last, if all you want is a report then using PROC MEANS or PROC TABULATE will be sufficient. You can use output sent to the LISTING window, if all you need is a plain report or you can use ODS to create HTML, RTF or PDF report output.

But, if you need to create a SAS dataset of the averages, then you will need to investigate either the ODS OUTPUT statement or the OUTPUT statement for PROC MEANS or the OUT= option for PROC TABULATE.

The example code below shows how to find the average height for each birth year and the average height for every year and gender combination. Documentation for PROC MEANS is here:
http://support.sas.com/documentation/cdl/en/proc/61895/HTML/default/a000146728.htm

TABULATE here:
