Worksheet arrays Limited by available memory. Also, arrays
cannot refer to entire columns. For example,
an array cannot refer to the entire column
C:C or to the range C1:C65536. However, an
array can refer to the range C1:D65535
because the range is one row short of the
maximum worksheet size and does not include
the entire C or D column.
