The one dimension in this sense does not represent any spatial 485 !! dimension, it merely represents an arbitrary number of single values 486 !! i.e. the fields recieved are simply an array (which may be of size 1) 487 !! of 0 dimensional fields. 484 !! receipt of 0D fields. 485 !! The fields are recieved into a 1D array buffer which is simply a 486 !! dynamically sized sized array (which may be of size 1) 487 !! of 0 dimensional fields. This allows us to pass miltiple 0D 488 !! fields via a single put/get operation. 488 489 !!---------------------------------------------------------------------- 489 INTEGER , INTENT(in ) :: items ! variable index in the array 490 INTEGER , INTENT(in ) :: kid ! variable index in the array 490 INTEGER , INTENT(in ) :: nitems !
