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

Answer / nizam&
For every record in an ESDS, RBA value will be
auto-generated, so we cannot insert a record in between the
records. what ever the data entered, will be abends at the
bottom for each REPRO.
