$global:ProjectName = $null

function RunFirst(){

RunSecund

Write-Host $global:ProjectName

}

function RunSecund(){

$global:ProjectName = "a name"

}

In RunSecund I get:

The variable ‘ProjectName’ is assigned but never used. PSScriptAnalyzer(PSUseDeclaredVarsMoreThanAssignments)

Question 2

Easy, don’t use global variables!

Although, if you must, you can suppress PSSA warnings with SuppressMessageAttribute:

function RunSecund(){
    [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUserDeclaredVarsMoreThanAssignments', '', Scope='Function')]
    $global:ProjectName = "a name"
}
