Hey people

I have written a powershell script, it has a menu system, that goes to a sub menu. and i in the sub menu,
I want one of the options to be back to main menu. How can i achieve this. or a command i can use to do this, or go back to a specific part of the script

script is

# PowerShell console window Style
$pshost = get-host
$pswindow = $pshost.ui.rawui

    $newsize = $pswindow.buffersize
    
    if($newsize.height){
        $newsize.height = 3000
        $newsize.width = 150
        $pswindow.buffersize = $newsize
    }

    $newsize = $pswindow.windowsize
    if($newsize.height){
        $newsize.height = 50
        $newsize.width = 150
        $pswindow.windowsize = $newsize
    }

# MAIN Menu system
$Loop = $true
While ($Loop)
{
    write-host
    write-host                                              ' 1)   go to menu1'
    write-host                                              ' 2)   go to menu 2'
    write-host                                              ' 3)   exit'
                                       

    

    $opt = Read-Host "Select an option [0-3]"
    write-host $opt
    switch ($opt)


"1" {
$Loop = $true
While ($Loop)

{   write-host
    write-host                                              ' 1)   script 1'
    write-host                                              ' 2)   script 2'
    write-host                                              ' 3)   script 3'
    write-host                                              ' 4)   script 4 '
    write-host                                              ' 5)   script 5 '
    write-host                                              ' 6)   back to Main Menu'
    write-host                                              
    

    $opt = Read-Host "Select an option [0-6]"
    write-host $opt
    switch ($opt)


"1" { #script}


"2" { #script}

  "3" { #script# }


  "4" {#script }

  "5" {#script #}

  "6" {???????????}

      default {"$_ is an invalid choice"}

      }
   }
 


}

"3"  {Exit }
      default {"$_ is an invalid choice"}

      }
   
   }

There is lot of menus available on the internet. Why reinvent the wheel.

I personally do like a little modified
http://mspowershell.blogspot.cz/2009/02/cli-menu-in-powershell.html

It only works on standard powershell console, in powershell_ise or other GUI tools it throws some errors :(
I use this menu a lot, for Exchange purposes (common tasks, getting some info..) and so on.
