Renumbering The Registers - HP 8647A Operation And Service Manual

Memory
5 . DEL Press (DEL) and a register number (00 through 99) to delete that
register. The specified register is deleted from the currently selected
sequence only; registers in other sequences you have set up are not
affected. After you have deleted a register, you
will
not be able to
recall that register number until you have saved operating settings in
it again.
Note The register number is immediately deleted from the sequence when
the delete entry is completed. However, the settings contained in the
register are recalled when you delete the register so you can re-save
the settings
if
you need to.
Renumbering the Registers
If
you use the arrow keys to recall the registers in sequence, the
deleted register number will be skipped. If you wish to eliminate the
skip, you can do so by moving each register following the deleted
register back one register number. To delete an entire sequence,
delete each register in the sequence.
