I understan what an array is but I don't understand how to set them.

I'm trying to take the info from a .dat file and set each line as part of the array.

code:
Computer1
Computer2
Computer3
Computer4
This is the section in my script where I want to set the array. It's marked with the arrow.
code:
 	$SelectedDomain = $DomainBox.Text
	shell '%comspec% /c net view /domain:$SelectedDomain | Find /i "\\" > Domain.dat'
	$nul = open (2,Domain.dat,2)
	$Domain = Readline(2)
	Do
	Select
		Case Substr($Domain,1,12) = ""
			$= $Form.MsgBox("Could not find $SelectedDomain Domain", "Domain not found")
			$Nul = Close(2)
			Del Domain.dat
			Exit
		Case Substr($Domain,1,2) = "\\"
			$CompListBox.Additem (Rtrim(Substr($Domain,3,)))
			(Rtrim(Substr($Domain,3,)));<---------------------------------------------------------------Add this to an array
		Case 1
	EndSelect
	$Domain = Readline(2)
	Until $Domain = ""
	$Nul = Close(2)
	Del Domain.dat
Thanks
