In PowerShell, you can initialize multiple variables in just one line. The following line sets all variables to the value 1:

$a = $b = $c = $d = 1

To swap variables, list variables as comma-separated lists (actually, PowerShell treats your lists internally like arrays):

$a = 1; $b = 2
$a, $b = $b, $a
$a; $b
