\starttext

\setbox\scratchbox\vbox{\input knuth\par}

\getnoflines\htdp\scratchbox

Your text has \noflines\ lines.

\stoptext

How do you substract/add a number from/to \noflines ?

I tried

\thinrules[n=\advance\the\noflines by -2]
\thinrules[n=\advance\noflines by -2]
\thinrules[n={\advance\the\noflines by -2}]
\thinrules[n={\advance\noflines by -2}]

neither works.
