Variables and Folders
kCurrent 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
Variable Types
ClassPad variables can be broadly grouped into three types: general variables, system variables, and local variables.
Variable Type | Description |
General 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 | System variables are |
| 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 |
|
|
Local Variables | 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 |
| |
| local variable by including the “Local” command in a program. Any |
| variable specified as the argument of a program or a |
| function is automatically treated as a local variable. |
