Angle menu
%=
%= displays the choice of two submenus that enable
you to specify the angle unit modifier as degrees (º), minutes
('), seconds ("), radian (r), or convert units using 4DMS. You
can also convert between rectangular coordinate form (R) and
polar coordinate form (P).
Choose an angle mode from the mode screen. You can
choose from DEG (default) or RAD. Entries are interpreted
and results displayed according to the angle mode setting
without needing to enter an angle unit modifier.
If you specify an angle unit modifier from the Angle menu, the
calculation is performed in that angle type, but the result will
be given in the angle mode setting.

y, z, t, a, b, and c. You can store a real number or an
expression that results in a real number to a memory variable.
L lets you store values to variables. Press L to store a
variable, and press z to select the variable to store. Press
< to store the value in the selected variable. If this
variable already has a value, that value is replaced by the
new one.
z acesses the variables. Press this key multiple times to
choose x, y, z, t, a, b, or c. You can also use z to recall the
stored values for these variables. The name of the variable is
inserted into the current entry, but the value assigned to the
variable is used to evaluate the expression.
%h recalls the values of variables. Press %h
to display a menu of variables and their stored values. Select
the variable you want to recall and press <. The value
assigned to the variable is inserted into the current entry and
used to evaluate the expression.
%{ clears all variable values. Press %{
and select 1: Yes to clear all variable values.
