Here is my version Tone...

  node_name = allot( {8, Byte}),  -- char[8] means fixed size of 8 bytes
  node_parm = allot(Ptr),   -- struct node *parm[MAXP] means a pointer to an
array of MAXP node structures.
  node_tag = allot(Word),
  node_value = allot( {8, Byte}), --  double means double-precision floating
point value
 node_sx     = allot( Word ),
 node_sy     = allot( Word ),
 node_px     = allot( Word ),
 node_py     = allot( Word ),
 node_ay     = allot( Word ),
 node_kind   = allot( Word ),
 node_nump   = allot( Word ),
 node_msg    = allot( Lpsz ),
 node_next   = allot( Ptr ),
 sizeof_node = allotted_size()
