2.7.4 ⁂General Iteration with TeX's `\loop`

If you want a more general purpose way of repeating a block of code, you can use

\loop ⟨code⟩\if… \repeat

This repeats ⟨code⟩ while the given condition is true. The \if… part should be one of TeX's conditionals, such as \ifnum, without the terminating \fi.

Example:

For example, to print the numbers from 1 to 10:

\newcount\mycount
\loop
 \advance\mycount by 1\relax
 \the\mycount.
\ifnum\mycount<10
\repeat

This produces:
