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.
