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.
