Many thanks for your reply, Aditya.

This is the first time I see that way of wrapping an argument.

In any case, I cannot compare to a number:

  \startluacode
    userdata = userdata or {}
    function userdata.numbersfname(name)
        return string.match(name, "%d+")
    end
  \stopluacode

  \define[1]\numbersfname
      {\cldcontext{userdata.numbersfname([==[#1]==])}}

  \starttext
  \numbersfname{abc123}

  \numbersfname{\env{fname}}
  \doifelse{\numbersfname{\env{fname}}}{123}{yes}{no}
  \stoptext

I don’t know why both strings don’t match.

Many thanks for your help,

Pablo
