Powershell. How to supplement a variable with text to get the full text later?

Question

PowerShell

Good afternoon.
The test is supplemented with the help of two functions and should eventually be a whole text, that is, a
script like this:

function funct1 {
    $Msg +="Привет"
    $Msg +="Друзья!"
}

function funct2 {
        $Msg += "Как дела?"
}

funct1
funct2
Write-Host $msg

The result should be This:
Hello Friends! How are you?
But in response, silence ...
Please tell me what's wrong? Thanks in advance

Answer 1

Either add global: before the variable name, or use the return value:
VARIABLES AND SCOPE
By default, variables are available only in the scope in which they are created.
For example, a variable that you create in a function is available only within the function. A variable that you create in a script is available only within the script (unless you dot-source the script, which adds it to the current scope).
You can use a scope modifier to change the default scope of the variable. The following expression creates a variable named "Computers". The variable has a global scope, even when it is created in a script or function.
$global:computers = "Server01"For more information, see about_Scopes.

function funct1 {
    $Msg ="hello"
    $Msg +="friends!"
  return $Msg
}

function funct2 {
        $Msg += "how are you?"
    return $Msg
}

funct1
funct2
Write-Host $Msg
