Hi:
I think the amount of space that is used to separate the footnote from the table is 2 spaces when you use BODYTITLE, (same as when you use STARTPAGE). In the future, there will be a way to decrease this amount of space -- either through the measured RTF destination (in 9.2) or with a style element, as described here:
http://support.sas.com/rnd/base/new92/92measuredrtf.html (see the description of the PARSKIP style element).
Sadly, however, I do not think this element works in 9.1.3 with the "classic" RTF destination. So you may need to keep post processing the file to remove the spaces that you don't want.
