Hi Robert,

it isn’t the use of \input. The problem is that you only get one level
of expansion.

If you add \input directly to letter:section:content, such as in:

    \startsetups[letter:section:content]
    \input knuth \relax
    \stopsetups

You will have \input expanded. But in the text itself \TeX\ and
large||scale won’t be expanded.

I have no idea why this happens. And I don’t know how to fix it. Maybe
Wolfgang knows what is happening here.

If I had to guess, it might be that \directsetups only allows a level of
expansion. But I may be plainly wrong.

A way to avoid the issue is to add the letter content directly to the
\startsetups[letter:section:context]. And rememmber that you have only
one level of expansion.

Just in case it might help,

Pablo
