11Path Arrays are used to define the regular constituents of a
12connections grid. As such, they are most often found as members
13of Mesh Arrays. While it is possible to use Path Arrays
14directly to define 1-dimensional regular connections, they will not be recognized
15through the usual  #!F-adobe-times-bold-r-normal--18*   DXQueryGridConnections #!EF interface, and, in some cases,
16will not be handled without expansion. It is therefore preferable to
17use  #!F-adobe-times-bold-r-normal--18*   DXMakeGridConnections #!EF and  #!F-adobe-times-bold-r-normal--18*   DXQueryGridConnections #!EF to define and
18access 1-dimensional regular grids. #!N #!N Array handles offer a simple
19mechanism to access individual elements of a Path Array without expansion.
