is there a way to do a Superscript within the Paragraph function like the following?

(example.)
define(&variable, string, @(72,1,20))

setstyle(&default)
beginparagraph(0,6,0,'left',0.1598)
show('Copyright ')
setstyle(&small_font)
rmoveto(0,-0.06)
show(char(169))
setstyle(&default_font)
endparagraph
