Other commands that search the current path are RCL and PRVAR
(print variables).
Note that none of the actions that search the current
path can alter the variable.
Since the HOME directory is always on the current path, the calcu-
lator can always find variables in the HOME directory. You might
choose to limit the contents of the HOME directory to subdirectories
and those variables you want always available.
Directory Structure. The diagrams below show the directory struc-
ture you created in chapter 4. In the first diagram, HOME is the
current directory; in the second, EE; and in the third, SP2. Each dia-
gram uses the following symbols.
