[texhax] Plain TeX headline issue

[Rodolfo Medina]

Hi.

In order to have the section name in the headline, I've been using the plain
TeX commands `\mark' and `\botmark'.  But, suppose that I want the section name
in the leftheadline and the subsection name in the rightheadline: then I'd need
two different \mark(s), whereas \mark is just one.  Can anyone suggest how it
is possible to achieve what i want?

Thanks for any help
Rodolfo
