Clear captured output/return value in a Powershell function

Question

Is there a way to clear the return values inside of a function so I can guarantee that the return value is what I intend? Or maybe turn off this behaviour for the function?<

Answer 1

Set variable scope to script or global.

function Get-Greeting {
    'Hello Everyone'
    $greeting = 'Hello World'
    'Ladies and Gentlemen'
    $script:greeting = $greeting
}

Get-Greeting
$greeting <== 'Hello World'
