Please lets not , Just -make sure- that the documentation
say that this reflects the 'rounding factor in the case of
linear arrays . Adding this keyword maybe appears as
the best way but then we'll have people adding 'rounding xx'
to type 5 arrays & wondering why that doesn't work .
I vote for maintaining the Doc's , that say if this is a linear
type array then the chunksize really refers to the rounding
factor for this array . And make chunksize mandatory through out
all arrays . My .02 ? . Tia, JimL
