Powershell function syntax

function name() {
	param(
	  [Parameter(Mandatory)]
	  [string]$one = "default,
	  [int]$num
	)
	return $something
}

• function parameters are defined in param
• comma separated values
• option to make a parameter mandatory

Calling a function

name $one $num
name -one $one -num $num

The function/param syntax also works for global arguments when executing a Powershell script.
