I have the a footnotes "QS= 50th percentile of the data" how can I supercript  and subscript the "th" in footnotes? in this case only superscript needed but I want to learn how  I can do subscripts as well. Thanks

Here's a good resource:

Tested and it seems to work here:

ods escapechar='^';
proc print data = sashelp.class;
	footnote "QS = 50^{super th} percentile of the data";
	footnote2 "QS = 50^{sub th} percentile of the data";
run;
