PS ~ Multi XOR & Set Values

Let's begin with XOR

multi xor in PowerShell with unlimited variables
so there are basic things like AND - OR ... and also XOR
xor is different because it returns $true only if one of the statements is true
you want that use will able to choice between x,y,z but not x,y or y,z
for basic xor use :: $a -xor $b

for more than 2 variables, we can convert Varialble into [bool]
found a great solution ... here
$var_1 = $item_1 -as [bool]
$var_2 = $item_2 -as [bool]
$var_3 = $item_3 -as [bool]
and the same for each item...

if this statement is true :: ($var_1 + $var_2 + $var_3 == 1)
it means the user chooses Only 1 option

multi option to Set variable

let's say you use foreach statement.
$selected is the variable you want to be set in every loop.

Hard labor way .....

Code:

Switch ($Selected)
  {
    "Item" { $Item = $true }
  }

if we like to work easily...

Code:

New-Variable -Name $Selected -Value 1 -Force -Scope 1 -PassThru -ErrorAction SilentlyContinue | Out-Null
Set-Variable -Name $Selected -Value 1 -Force -Scope 1 -PassThru -ErrorAction SilentlyContinue | Out-Null

Sometimes it fails too.
is such a case ... as here
there is this statement too.

Code:

$PSCmdlet.SessionState.PSVariable.Set($variable,$value)
