3.17.5. Horizontal Dependencies
-------------------------------

LRB is dependent on the :ref:`Form Column<form-column-dep-by>`.

LRB must have the same number of codes and the same number and type of
ops as the Form entry on which it depends.

The codes allowed in a given position in LRB are determined by the 
code in the corresponding position in Form:

===================  =  =  =  ==  ==  =  ==
Form code            L  R  B  LF  RF  H  WB 
===================  =  =  =  ==  ==  =  ==

.. _lrb-column-horz-dep-continued-note:

.. note::

   If the code in Form is :term:`continued` (ending with ``~``), the
   corresponding code in LRB must be the same as the LRB code associated with
   the Form code being continued on the immediately preceding line with a 
   communicative act on the part of the speaker.

   Example::

      Line 1: 
        Form: point + hold
        LRB: R + L
      Line 2:
        Form: point~
        LRB: R
