Perhaps your install of SAS is 9.0 instead of 9.1??? If you look at the site, the 9.1.3 options are in yellow, which leads me to believe that all the others were pre-production in SAS 9.1.
When I tried this code in SAS 9.1.3:
ods rtf file="c:\temp\test.rtf" headery=320 footery=1100;
proc print data=sashelp.class;
title 'where is title';
footnote 'where is footnote';
ods rtf close;
the title (HEADERY) is closer to the top of the document than the footnote (FOOTERY), which is a different distance from the bottom. Since the value for HEADERY and FOOTERY is in TWIPS (twentieths of a printers point), it seems to me possible that 0 twips is not a valid value for RTF -or- that Word doesn't like 0 twips, somehow. When I tried using 0 as the value for these 2 options, it almost looked like Word was using my NORMAL.DOT values.
You might consider contacting Tech Support for help with this problem.
