How to confirm your script worked?

I have this code which works.

$computers = (get-ItemProperty hklm:\SOFTWARE\Microsoft\MPSD\OSD).OSDComputerName 

$GetOU = (get-ItemProperty hklm:\SOFTWARE\Microsoft\MPSD\OSD).OSDDomainOUName

$dom = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()

$root = $dom.GetDirectoryEntry()

foreach($computer in $computers){

$search = [System.DirectoryServices.DirectorySearcher]$root

$search.Filter = "(cn=$computer)"

$result = $search.FindOne()

$computerToMove = [ADSI]$result.path

$computerToMove.psbase.Moveto([ADSI]"LDAP://$GetOU")}

This is run as part of a CM2012 OS deployment task sequence.   It reads the values set in the registry and then moves the computer account to the OU specified.  

How can I confirm it all worked?   I want to add something like this.

If MOVE worked THEN

$text = "computer moved worked"

$text | Out-File 'c:\windows\MGH\logs\ADTasks.txt' -Append

ELSE "it did not work"

Do I have to add code that checks the new OU for the machine name?  That makes sense but I was really wondering if the move command generates any sort of EXIT CODE that I can capture "Live" in the code without checking AD.
