These functions are part of the OpenMaple interface to Microsoft(R) Visual Basic(R).

The RTableLowerBound function returns the lower bound of dimension dim for the given rtable, rt.  For rtables with subtype Matrix and Vector, this always returns 1.  For Arrays, this command is equivalent to calling lhs([rtable_dims(A)][dim]), or op([2,dim,1],rt).

The RTableUpperBound function returns the upper bound of dimension dim for the given rtable, rt.  For rtables with subtype Matrix and Vector, this is equivalent to to calling op([1,dim],rt). For Arrays, this command is equivalent to calling op([2,dim,2],rt). For all rtables, it is equivalent to calling rhs([rtable_dims(A)][dim]).
