Clearing Storage Registers
Even though you have recalled the contents of a storage register into
the displayed X-register, the number also remains in the storage
register. You can clear primary storage registers in either of two ways:
u To replace a number in a single storage register, merely store
another number there. To clear a storage register, replace the
number in it with zero. For example, to clear storage register
R,, press 0 B 2.
# To clear all primary storage registers back to zero at one time,
press [ . This clears all primary storage registers, while
leaving the automatic memory stack and the secondary storage
registers unchanged.
