Arithmetic with Stored Variables
Storage arithmetic and recall arithmetic allow you to do calculations with a
number stored in a variable without recalling the variable into the stack. A
calculation uses one number from the X–register and one number from the
specified variable.
Storage Arithmetic
Storage arithmetic uses
H
,
H
,
H
y
, or
H
p
to do
arithmetic in the variable itself and to store the result there. It uses the value in
the X–register and does riot affect the stack.
New value of variable = Previous value of variable {+, –,

} x.
For example, suppose you want to reduce the value in A(15) by the number in
the X–register (3, displayed). Press
H
A. Now A = 12, while 3 is still
in the display.
