\unprotect

%D This module is suggested by Wolfgang Schuster who also prototyped
%D it and came up with the rationale:
%D
%D This module provides an easy way to use natural in a similiar
%D way as the older table module (based on the \TABLE\ macros) and
%D the newer tabulate module.
%D
%D You can see the advantage in the following table, once created
%D with the new macros and once with the normal macros provided
%D with the natural table module.
%D
%D Let us start with the original macros:
%D
%D \starttyping
%D \bTABLE
%D   \bTR
%D     \bTD Text 1 \eTD
%D     \bTD Text 2 \eTD
%D   \eTR
%D   \bTR
%D     \bTD Text 3 \eTD
%D     \bTD Text 4 \eTD
%D   \eTR
%D \eTABLE
%D \stoptyping
%D
%D Watch how the new macros use less code:
%D
%D \starttyping
%D \startTABLE
%D \NC Text 1 \NC Text 2 \NC\NR
%D \NC Text 3 \NC Text 4 \NC\NR
%D \stopTABLE
%D \stoptyping
%D
%D The actual code differs from the prototype that it does not need
%D to collect whole rows and parse them but looks ahead instead.

\def\startTABLE
  {\dosingleempty\dostartTABLE}

\def\dostartTABLE[#1]%
  {\bgroup
   \bTABLE[#1]%
