Answer / harsha

Freespace(CI%,CA%)
it means
1 "How much percentage of CI is to be left free"
2 "How much percentage of CA is to be left free"

Free space is responsible for record splitting and Spanned
record.

In KSDS, Record splitting and Spanned record is possible
while in ESDS, it is not possible.
In ESDS, one cannot Insert a record in between
one cannot Delete a record in between
one cannot Increase the length of a record in between
