Your second frame leads to an error because the \in and \leftarrow are not in math mode. Because your LaTeX code is explicitly in an export LaTeX environment, org doesn't do its usual magic with LaTeX entities so you need to put the maths delimiters yourself: > #+begin_src latex > \defverbatim\SomeCode{ > \begin{alltt} > x $\in$ {0, 1, ..., n} > z $\leftarrow$ x + 1 > \end{alltt} > } > #+end_src When in doubt, export to LaTeX (C-e l b) and have a look at the LaTeX. Also then run pdflatex yourself on that LaTeX code to see what errors come up. HTH, eric -- : Eric S Fraga via Emacs 28.0.50, Org release_9.4-143-g9a1549
