is not #!F-adobe-times-bold-r-normal--18* NULL #!EF , this routine returns in #!F-adobe-times-bold-r-normal--18*
*count #!EF the number of points referred to by the Path
Array #!F-adobe-times-bold-r-normal--18* a #!EF ; this is one more than the

Path Arrays are used to define the regular constituents of a
connections grid. As such, they are most often found as members
of Mesh Arrays. While it is possible to use Path Arrays
directly to define 1-dimensional regular connections, they will not be recognized
through the usual #!F-adobe-times-bold-r-normal--18* DXQueryGridConnections #!EF interface, and, in some cases,
will not be handled without expansion. It is therefore preferable to
use #!F-adobe-times-bold-r-normal--18* DXMakeGridConnections #!EF and #!F-adobe-times-bold-r-normal--18* DXQueryGridConnections #!EF to define and
access 1-dimensional regular grids. #!N #!N Array handles offer a simple
mechanism to access individual elements of a Path Array without expansion.
#!N #!N Return Value #!N #!N Returns #!F-adobe-times-bold-r-normal--18* a #!EF or
returns #!F-adobe-times-bold-r-normal--18* NULL #!EF and sets an error code. #!N #!N
