Look at either PROC REPORT or consider using PROC SUMMARY along with PROC PRINT, or PROC MEANS. The SAS support website http://support.sas.com/ has much to offer, with SAS-hosted documentation and also technical / conference reference material - suggest using the SEARCH facility there or use a Google advanced search, possibly, by coding the parameter "site:sas.com" to limit your search.
