104 Alphabetical Listing
Local
Catalog >
Local Var1[, Var2] [, Var3] ...
Declares the specified vars as local
variables. Those variables exist only during
evaluation of a function and are deleted
when the function finishes execution.
Note: Local variables save memory because
they only exist temporarily. Also, they do
not disturb any existing global variable
values. Local variables must be used for For
loops and for temporarily saving values in a
multi-line function since modifications on
global variables are not allowed in a
function.
Note for entering the example: For
instructions on entering multi-line program
and function definitions, refer to the
Calculator section of your product
guidebook.

Note: The Lock command clears the
Undo/Redo history when applied to
unlocked variables.
