The freespace in the sequence set (represented by spaces) is quite different from the freespace pointers. This is used to display the space that is unused in the sequence set record. If all of the CIs in the control area for the data are already being used, then this area is of no significance (remember, all of the CIs are being used if the freespace pointers value is zero). However, if there are unused CIs in the data's control area, this area can become much more important. We will discuss this more in Unreferenceable Data Control Intervals. For now, just remember that the value under the column FREE SPACE represents the number of empty positions in the sequence set record that can be used for other purposes.
