kVariable 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 or using the [Setup] menu (page

* 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 protect 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
•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.
