For various reasons, I have to use TeX rather than LaTeX for a short document. I need to be able to insert a short blank underline within a paragraph. In LaTeX, this would be done easily with \rule{length}{thickness}
. What is the plain TeX equivalent?

For a long underline you can use \hrulefill
inside a box:
Some text with no real sense, just to fill
\hbox to 6em{\hrulefill} some space.

\def\rule#1#2{\leavevmode\vrule width #1 height #2 depth 0pt\relax}
depth
.
