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.
