Command for setting a lock to prevent deletion/overwriting
Command for revoking a lock to prevent deletion/overwriting
CTABUNLOCK unlocks the curve tables locked with CTABLOCK. Curve
tables which are involved in an active coupling remain locked and
cannot be deleted. The lock with CTABLOCK is unlocked as soon as
the 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 CTABUNLOCK again.
Number (ID) of the curve table to be locked/unlocked
When a curve table range CTABLOCK(<n>,<m>)/
CTABUNLOCK(<n>,<m>) is locked/unlocked, <n> is used to specify
the number of the first curve table in the range.
