RECOVERY (default) and SPEED are mutually exclusive.
Recovery preformats the control areas during the initial
dataset load, if the job fails, you can restart but you must
have a recovery routine already written to restart the job.
SPEED does not preformat the CAs. It is recommended that you
specify SPEED to speed up your initial data load.

If fspc(100 100) is specified does it mean that both the control interval and control area will be left empty because 100 % of both ci and ca are specified to be empty?
