ATM there is no relation between latex$SetCategory and 'output tex on'.
The source contain comment:
++ 09/09/92 RSS added latex and hash
so its seems that original developers want to replace the current
TeX output with new one.
OTOH almost all code relevant to TeX output already is in the algebra.
Try:
q2 := (x+y)/(x+1)
of2 := q2::OutputForm
of2::TexFormat()
tex(of2::TexFormat())
The last command gives a list of strings, the low level output routives
will print each string on separate line. So one could implement
'latex$SetCategory' in terms of 'tex$TexFormat()'.
Concerning plain TeX versus LaTeX: I think ability to output plain
TeX is valuable and I woul like to keep it. Given that now LaTeX
is more important we should be able to output idiomatic LaTeX too.
So we should have switches in TexFormat to choose between TeX
and LaTeX.
