Using Local Variables
A local variable is a temporary variable that exists only while a user-defined function is
being evaluated or a user-defined program is running.
Example of a Local Variable
The following program segment shows a For...EndFor loop (which is discussed later in this
module). The variable i is the loop counter. In most cases, the variable i is used only while
the program is running.
Local iÀ
For i,0,5,1
Disp i
EndFor
Disp i
À
Declares variable i as local.
