Editing Parameter (computer programming) (section)

=== Named parameters ===
Some programming languages—such as [[Ada (programming language)|Ada]] and [[Windows PowerShell]]—allow subroutines to have [[named parameter]]s. This allows the calling code to be more [[self-documenting]]. It also provides more flexibility to the caller, often allowing the order of the arguments to be changed, or for arguments to be omitted as needed.

PowerShell example:
<syntaxhighlight lang="powershell">
function jennifer($adjectiveYoung, $adjectiveOld) {
    "Young Jennifer: I'm $adjectiveYoung!"
    "Old Jennifer: I'm $adjectiveOld!"
}
</syntaxhighlight>
<syntaxhighlight lang="ps1con">

PS  > jennifer 'fresh' 'experienced'
Young Jennifer: I'm fresh!
Old Jennifer: I'm experienced!

PS  > jennifer -adjectiveOld 'experienced' -adjectiveYoung 'fresh'
Young Jennifer: I'm fresh!
Old Jennifer: I'm experienced!
</syntaxhighlight>
