Note how you have to duplicate the last case value here because of
the previous XOR.  Keeping lists like this intact when you add/remove
values to test for is a pain -> use a macro to do the work.

Yes, this is the normal way to do it for few and/or widely separated
(e.g. ASCII) values to test for.  If the cases to test for are all
near each other, then a jump table might be useful (with code handling
unused entries of course).
I actually use some macros for this, so I can write:

      switch
      case "?",Copyright     ; xorlw "?":bz Copyright
      case "G",Go
      case "K",Kill
      case "Z",Sleep
      endswitch
      ; code continues here if no match

The switch and endswitch macros handle setting up a compile-time
variable to keep the last case value in (required because of the XOR)
