With functions function Get-Something { Param ( [Parameter(Mandatory=$true, Position=0)] [string] $Name, [Parameter(Mandatory=$true, Position=1)] [int] $Id ) # Write the output to the console Write-Output "Name: $Name, Id: $Id" } Get-Something "Alice" 42 If you were to call Get-Something("Alice", 42) It would pass "Alice", 42 to the first parameter. You can use named parameters to get round this, e.g. Get-Something -Name "Alice" -Id 42 Still a bit of a gotcha!
