In Powershell, what's the equivalent to NOTHING from VBScript?

Thanks!

There is no exact equivalent due to lazy garbage collection, but you can get
the same effect on variable association by using Remove-Variable. For
example:

$MyVar = 1234
Remove-Variable MyVar

Come to think of it, John's suggestion is a close equivalent as well. The
distinction between his method and mine is that if you set a variable to
$null, the variable still exists (which is the case with setting a variable
to Nothing in VBScript).
