However, I'd use the \str_if_eq:xxTF test here, as you want a string comparison \documentclass{minimal} \usepackage{expl3} \begin{document} \ExplSyntaxOn \str_if_eq:nnTF{a}{\c_job_name_tl}{true}{false} \ExplSyntaxOff \end{document} (This will work with \jobname as well, but the 'official' interface to that in LaTeX3 is \c_job_name_tl.) -- Joseph Wright
