The length property is read only and returns a Long value which is the number of items in the collection.
For JScript consistency, length should be lowercase.
Set objShell =
WScript.CreateObject("WScript.Shell")
Set objSysEnv =
objShell.Environment("SYSTEM")
WScript.Echo "There are",
objSysEnv.length, "System environment variables."There are 14 System environment
variables.This VBScript code uses the length property to report the number of system environment variables currently defined.
