Lesson 14: Organizing Variables
Whenever a variable is created, it is put into the current
d i r e c t o r y .
Directories let you organize variables into meaningful collections. They

at once. Only one directory
at
a

active, or

The
current
directory is
shown
in
the stack
display in
the

above the stack levels. (At the moment it shows that
