Current Folder
The current folder is the folder where the variables created by applications (excluding
eActivity) are stored and from which such variables can be accessed. The initial default
current folder is the “main” folder.
You can also select a user folder you created as the current folder. For more information
about how to do this, see “Specifying the Current Folder” on page 1-8-3.
Variable Types
ClassPad variables can be broadly grouped into three types: general variables, system
variables, and local variables.

Description
General Variables
System Variables
Local Variables
A general variable is one you create using any name you want.
Unless you specify otherwise when you are creating it, a general
variable is stored in the current folder. You can use the same name
for multiple variables, as long as each of them is stored in a different
folder. General variables can be deleted, renamed, etc.
System variables are pre-defined reserved variables used by
ClassPad applications and other system operations. They are stored
in the “system” folder. System variables can be accessed without
specifying the folder name, and can even be accessed from another
folder. Since system variable names are reserved words, they cannot
be renamed. Whether you are allowed to delete or change the
contents of a system variable depends on each variable.
• For the names of and detailed information about system variables,
see the “System Variable Table” on page α-7-1.
A local variable is a variable that is temporarily created by a defining
function, program, or other operation for a particular purpose. A local
variable is deleted automatically when execution of the program or
user-defined function that created it is complete. You can create a
local variable by including the “Local” command in a program. Any
variable specified as the argument of a program or a user-defined
function is automatically treated as a local variable.
