a label designator
(listed above) or V to
transfer the position of
the calculator to the
designated label. If it is
a program instruction,
program execution
continues. If it is not a
program instruction,
only the position
change occurs (page

number is stored in R
I
,
t V will effect a
transfer to a line
number (page 109).
t “ nnn Go to
