understanding the For Each Loop

I'm new to scripting and programming.

In the following and similar scripts, I noticed that there exists a 'objOperatingSystem' that is referred to in the 'For Each' loop. I understand that 'colSettings' is a variable that contains the WMI collection, but where does the 'objOperatingSystem' come from ?

Pls help. Thanks!!!

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" _
    & strComputer & "\root\cimv2")
Set colSettings = objWMIService.ExecQuery _
    ("Select * from Win32_OperatingSystem")
For Each objOperatingSystem in colSettings 
    Wscript.Echo "Available Physical Memory: " & _
        objOperatingSystem.FreePhysicalMemory

Solution

  • objOperatingSystem is a variable. For Each declared it. Basically, for every item in colSettings a variable named objOperatingSystem will be set to the current item, and the body of the for loop executed.
