To evaluate EQ2 with the values from SP2, you could execute EE (to

ing SP2 for SPI.
Returning to HOME
Assuming you're done for now with your electrical engineering prob-
lems, you can return to the HOME directory. Since HOME is a built-in
directory, its name is included in the MEMORY menu.
Switch to the HOME directory .
