As my nick suggests, I am just starting out with tex. Using plain tex, I am trying to create a document where certain paragraphs are separated by a centered horizontal line. I would like the separating line to be slighty larger than \hsize. I tried the following:
\parindent 0pt
\hsize 5in
{\hsize 6in \hrule}
\bigskip
x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x
%The "x x x ... x" above is the text of a dummy paragraph.
\bigskip
{\hsize 6in \hrule}
\vfill
\eject
\end
but it didn't work. The hrule width came out the same as the text width.
I would appreciate any advice as to how I can achieve the desired effect.
\hrule width6in
?
