Using XEQ for Evaluation
If an equation is displayed in the equation list, you can press
W
to
evaluate the equation. The entire equation is evaluated, regardless of the type
of equation. The result is returned to the X–register.
Example:
Evaluating an Equation with XEQ.
Use the results from the previous example to find out how much the volume of
the pipe changes if the diameter is changes to 35.5 millimeters.

.)
Changes cubic millimeters to liters.
The value of the equation is the old volume (from V) minus the new volume
(calculated using the new D value) — so the old volume is smaller by the
amount shown.
Responding to Equation Prompts
When you evaluate an equation, you're prompted for a value for each
variable that's needed. The prompt gives the variable name and its current
value, such as
