      I want to print content of the array. I have used following code for that

      use TeamSite::WFsystem ;

      $system = new TeamSite::WFsystem() ;

      @jobs = $system->GetActiveWorkflows();

      foreach $job (@jobs){

      print "$job \n" ;

      }

      why am I still getting reference to array printed out ?

        Because it seems that ->GetActiveWorkflows returns an array reference and not an array. Simply assigning to an array does not make the function return an array.

        Since numerous people have told you already that ->GetActiveWorkflows() returns an arrayref instead of an array, here's the code that does something useful with that:
        use TeamSite::WFsystem ; $system = new TeamSite::WFsystem() ; my $ar_jobs = $system->GetActiveWorkflows(); foreach my $job (@{$ar_jobs}){ print "$job \n" ; }
        Assuming that $job will contain something printable, of course.
        @{$ar_jobs} dereferences the arrayreference, which gives you the array that $ar_jobs references to. I usually prefix my arrayref and hashref variables with ar_ and hr_ respectively, so I can easily see what kind of reference I'm dealing with. This is not required, but imo easier to spot.
