Mastering Windows PowerShell Scripting - Third Edition

trap, scope, and continue

By default, if an error is handled by trap, script execution stops. The continue keyword can be used to resume a script at the next statement.

The following example handles the error raised by throw and continues onto the next statement:

& { 
    Write-Host 'Statement1' 
    throw 'Statement2' 
    Write-Host 'Statement3' 
 
    trap { 
        Write-Host 'An error occurred' 
        continue 
    } 
}

& { function Invoke-Something ...
