What do really think it means.

Had you have read the manual you would have seen that the parameter describes what percentage of free space to leave in the CI & CA at dataset load time.

The manuals can easily be reached by the manuals button at the top of this and every page.

Hi,

Percept it as - FREESPACE(ci% ca%) Abbreviated as FSPC.

where ci is the percentage of each control interval to be left free for insertions, ca is the percentage of control intervals in each control area to be left empty. Howevr, I would echo Expat Quote: read the manual

Sorry that I haven't explain in details..
I want to know if I code FSPC(0 0), then what percent of CI will be felt free and what percent of CA will left free?

e.g. if I code FSPC(100 100) then only one record will be loaded per CI and only one CI will be allocated per CA..

Thanks
Rahman
