To evaluate EQ2 with the values from SP2, you could execute EE (to
switch directories
back to EE) and then repeat step 2 above, substitut-
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 .

The menu label EE is the only sign of everything you created in
this chapter-EQI, EQ2, the subdirectories SPI and SP2, and all the
variables in them. This is a major advantage of directories: Viewed
from its parent directory, an entire directory-its variables and its own
subdirectories-appear simply as the name of the directory.
