Variables and Folders
Assigning Values and Other Data to a System Variable
As its name suggests, a system variable is a variable that is created and used by the system
(page 1-7-5). Some system variables allow you to assign values and other data to them,
while some system variables do not. For more information about which variables allow you to
control their contents, see the “System Variable Table” on page
α
-7-1.
Locking a Variable or Folder
Locking a variable or folder protects against inadvertently deleting it or changing its contents.
You can unlock a locked variable or folder to re-enable deletion and data assignment.
• Locking a variable disables the following operations on it: delete, overwrite, rename, and
move (to another folder).
• Locking a folder makes it impossible to delete or rename the folder.
Tip
• In terms of ClassPad variables, “lock” is completely different from “protect”. For more information
about “protect”, see “Variable Data Types” on page 1-7-3.
You can lock and unlock a variable or folder using either the Variable Manager or commands.
