While loop cuases argumental errors with cmdlets Powershell

Question

I was attempting to make a while loop for a input box and have it process it through another file though I keep getting a error that on another line it thinks its a positional argument

while ($true) {
$shell = Read-Host -Prompt "<"
Invoke-Command -ScriptBlock ([scriptblock]::Create((Get-Content ".\rescources\entry\Basehandler.ps1"))) -ArgumentList '$shell'
}

Error:

Read-Host : A positional parameter cannot be found that accepts argument 'Invoke-Command'.

You don't have any new line characters to separate the lines. Everything is on one line, so you need to separate cmdlets with a semicolon.

while ($true) {$shell = Read-Host -Prompt "<";  Write-Host "You entered $shell"} 

Personally, I like to put commands on separate lines to make it easier to read.

while ($true) {
    $shell = Read-Host -Prompt "<"
    Write-Host "You entered $shell"
}
