It is documented here in the IDCAMS manual:

publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/dgt1v403/3.2?DT=19990113080956

Quote:

FREESPACE(CI-percent[ CA-percent])
specifies the amount of space (percentage of space) that is to be left free after any allocation and after any split of control intervals (CI-percent) and control areas (CA-percent).

The amounts, as percentages, must be equal to or less than 100. If you specify 100% of free space, one record is placed in each control interval and one control interval is placed in each control area.

This parameter may be specified to alter the data component of a cluster or alternate index.

If the FREESPACE is altered after the data set has been loaded, and sequential insert strategy processing is being used, this allocation of free space may not be honored.

Abbreviation: FSPC
