Vista Tutorial - How can i pass values from external files

foreach ($computer in $computernames)
{
$strQuery = "select * from win32_pingstatus where address = '" + $computer
+ "'"
$wmi = Get-WmiObject -query $strQuery
switch ($wmi.statuscode)
## statuscode derived from

}

===================================================================================================
On the whole switch statement, i can put as statuscode.ps1 and subsitute as
...\statuscode.ps1 in my script. Therefore it becomes like this
foreach ($computer in $computernames)
{
$strQuery = "select * from win32_pingstatus where address = '" + $computer
+ "'"
$wmi = Get-WmiObject -query $strQuery
...\statuscode.ps1
}

However on the *main* script, i wish to retrieve the $value back, as i want
to include in other variables. How do i READ the $value in my main script ?
