I want to avoid using
\tmp. Is it possible to remove it while keeping the same output?
% Declare counters. \newcount\pages% \pages is given so you cannot remove it! \newcount\x \newcount\tmp % Initializing. \pages=9% Try it for an odd or even integer. \tmp=\pages \advance\tmp by 1 \x=1 \loop \ifnum\x<\tmp \noindent\hfill\the\x \advance\x by 1 \ifnum\x>\pages \hfill\null\endgraf \else \hfill\the\x\hfill\null\endgraf \fi \advance\x by 1 \repeat \bye
Note: Please don't use
e-TeX extension as I am learning Knuth's original TeX right now.
