Record Count Override—This column allows the computed Total Records value to be overridden, if
desired. The value entered in this column must be greater than zero (0) in order to be used.
Normally this column should remain blank.
Primary Data/Index—This section is composed of two columns. The first column, labeled Size (MBs),
shows the computed disk space requirement for the number of Total Records computed (or the
Record CountOverride, if set). This takes into account the actual size ofthe data in each record as well
as the primary index. The second column, labeled SFS Vol #, specifies which logical SFS data
