Variable Data Types
ClassPad variables support a number of data types. The type of data assigned to a variable
is indicated by a data type name. Data type names are shown on the Variable Manager
variable list, and on the Select Data dialog box that appears when you are specifying a
variable in any ClassPad application. The following table lists all of the variable data type
names and explains the meaning of each.

Variables and Folders
* Protected variable types
Some data types are protected. A variable whose data type is protected cannot be
overwritten with another variable, which protects variable contents from being inadvertently
altered. Data types whose names are marked with an asterisk in the above table are
protected.
Tip
• Note that whether or not a data type is protected is determined by the system. You cannot
change the protection status of a data type.
• Even when a variable is a protected data type, you can rename, delete, or move it. To disable
these operations, you need to lock the variable. For more information, see “Locking a Variable or
Folder” on page 1-7-10.
• The elements of the LIST data type can contain EXPR or STR type data only. The elements of
the MAT data type can contain EXPR type data only.
