Note: Displaying a result with or does not store that result. If you expect to refer later to a result, store it to a global variable. © (p/4)&maximum maximum © Using local variables A local variable is a temporary variable that exists only while a userdefined 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 i À For i,0,5,1 Disp i EndFor Disp i À Declares variable i as local. Note: When possible, declare as local any variable that is used only within the program and does not need to be available after the program stops. What causes an undefined variable error message? An Undefined variable error message displays when you evaluate a userdefined function or run a user-defined program that references a local variable that is not initialized (assigned a value). For example: Define fact(n)=Func Local m À While n>1 n¦m&m: n-1&n EndWhile Return m EndFunc À Local variable m is not assigned an initial value. 690 Programming
