How to do it...

The process is simple:

1. Create a copy of the 06-Start-Count.ps1 file.
2. Replace the first line with $MyScriptBlock = {. The file should now look like the following:

$MyScriptBlock = {
    param ($TotalTime = 25)

    $CurrentTime = 0

    while ($CurrentTime -le $TotalTime) {
        Write-Progress -Activity "Counting to $TotalTime" -Status "Elapsed time: $CurrentTime seconds" -PercentComplete ($CurrentTime / $TotalTime * 100)
        Start-Sleep 1
        $CurrentTime++
    }
}

3. Now, call the script with the dot calling operator so that the variable is loaded into the session.
4. Call the variable with the & calling operator to run the script. Optionally, pass a value to the TotalTime parameter:

PS> . ./ch11/07-Start-Count.ps1PS> & $MyScriptBlock 10PS> # Verbose version: ...
