#!I0 #!N Notes: #!N #!I30 #!N 1. These routines are suitable
for adding a small number of points and for rapid prototyping.
For better performance, see the description of #!F-adobe-times-bold-r-normal--18* DXAddArrayData #!EF and
the discussion of direct-access routines in #!Lirreg,dxall1071 h Irregular Arrays #!EL #!N #!I30 #!N 2.
These routines do not check the "dep" attribute of the component
being added to; thus, these routines do not perform correctly if
the component exists and has a dep "connections" attribute. #!I0 #!N
