You will find useful reference information and SAS documentation at the SAS support website http://support.sas.com/ and use the SEARCH box or a Google advanced search (using the site:sas.com Google parameter) to find topic material requested.

Hi -
Since you don't seem to have access to SAS/ETS you might want to review an earlier thread in this forum called "Time series analysis without ETS" (see: http://support.sas.com/forums/thread.jspa?threadID=2849&tstart=15).
For this kind of forecasting analysis in SAS/ETS the following data structure seems to be more appropriate:
Date Dependent
01APR2004 94
01MAY2004 592
01JUN2004 916
...
01OCT2008 10665

Thanks,
Udo
