Hello Hans,

what is the purpose of \hexstringtonumber{..}?

I would expect something like:

\unprotect
\setvalue{@@uc@@a}{10} \setvalue{@@uc@@A}{10}
\setvalue{@@uc@@b}{11} \setvalue{@@uc@@B}{11}
\setvalue{@@uc@@c}{12} \setvalue{@@uc@@C}{12}
\setvalue{@@uc@@d}{13} \setvalue{@@uc@@D}{13}
\setvalue{@@uc@@e}{14} \setvalue{@@uc@@E}{14}
\setvalue{@@uc@@f}{15} \setvalue{@@uc@@F}{15}

\def\dohexstringtonumber#1#2% FF
  {\the\numexpr\csname @@uc@@#1\endcsname * 16 +
               \csname @@uc@@#2\endcsname\relax}
\protect

\starttext
\hexstringtonumber{1E}
\hexstringtonumber{f5}
\stoptext

But your version just adds a " to the string...

Cheers, Peter
