Not sure I understand the question. Once the defines are there I 
can write following:

   | // Call luaF_close
   | mov CARG1, L                               // arg1 = L
   | mov CARG2, BASE                            // arg2 = base
   | call extern luaF_close                     // call luaF_close

As you can see above, CARG1, L, CARG2, BASE are all mnemonics 
that map to registers. However this is only defined in one place.
