Thanks to Nick Winter for his suggestion. I did think of that method as well. Both are similar in that you test it once as a variable and once as a number -- in either order, doing the second test if the first fails. I was just wondering if I was overlooking some other simpler possibility.

I would get x1 as a string, and then test it after your syntax line:

   syntax , x1(string)

   capture confirm new variable `x1'
   if _rc {
      confirm number `x1'
      if _rc {
         di as error "x1() must be a new variable name or a number"
         error 198
      }
      else {
         local isvar 0
        }
   }
   else {
      local isvar 1
   }
