Factorial in Basic

Example for versions VBScript 5.7, VBScript 5.8

This example shows iterative factorial calculation. Note that no overflow happens, though the type of factorial variable is inferred from its usage and never set explicitly. 

f = 1
For i = 0 To 16
   WScript.Echo(i & "! = " & f)
   f = f * (i + 1)
