in thread how to call a sub via variable in library

you have given the best understanding of which i did not even have... Although this is wrong here is what i want to accomplish: $self->&$testname($system). Execute sub '$testname' with '$system' as parameter in object '$self'. Could you help further with this???

    Depends what do you mean by "... in object $self"?

    I see two possible interpretations of that:

    1. You simply want to execute the sub named in $testname (whilst incidentally running inside a method of object $self); in which case all you need is:
      $testname->( $system );

      You'll probably need no strict 'refs'; for that.

    2. Alternatively, you might mean that you want to invoke the method of object $self, who's name is held in $testname; in which case all you need is:
      $self->$testname( $system );

      Seems to work fine with full strict.
