cannot be deleted. The lock with
lock applied due to the active coupling is unlocked when the coupling
is deactivated. This table can therefore be deleted. It is not necessary
to call again.

When a curve table range
locked/unlocked, is used to specify the number of the first curve

table in the range.
When a curve table range
locked/unlocked, is used to specify the number of the last curve
