PWB Unix is 1977. But get input from someone who was around at the time.
Why not use the preprocessor eqn(1) which means using definining the
delimiter at the start of the document with
.EN
ITYM .EQ above. :)
Yes, Sorry. Brain switched off. Nightime here.
groff mm(7) is already heavily extended; I think we should go ahead and
add strings for super- and subscripting unless someone can come up with
a really good reason not to.
Go for it. My only reason for using eqn(1) is tht 99% of my needs are
because of mathematics. You examples of footnotes to text and chemistry
formulae are clear examples where they are not needed. That said, I never
use superscripts for footnotes and use the 'roman' keyword in eqn(1) for
chemical formulae.
