Hi all ! First of all, thanks to everyone who replied on the previous multi-level question. I'm very well surprised by the level of the replies - I already have something working and got some mor einsight into Perl. Thanks ! Now, on the same subject, I have this multi-level hash and I'd like to loop on a hash that's declared inside another one. I can easily loop on the top declarations (Project1, Project2, Project3) like this: 
  while(($key, $value) = each(%projects)) {
    print "DEBUG $key = $value\n";
  }

But how about looping on Porject1's components (Software, Firmware) or the Project1 Software's own sub components (Database, SerialComms) ? Here's the structure (please don't look at it for syntax - it's mostly a representation I've made) : 
%projects = (
  Projects => {
   "Project1" => {
      version   => "3.41",
      status => "nul",
      components => {
     "Software" => {
        name => "controller",
        label => "RC_1.01",
        subComponents => {
          "Database" => {
            version = "1.01",
           }
           "SerialComms" => {
              version = "2.13",
           }
           }

           "Firmware" => {
           name => "I/O Interface",
            label => "RC_1.21",
        }
       }
     }

     "Project2" => {
      }
     "Project3" => {
      }
)

Cheers.
