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???

here is what i want to accomplish: $self->&$testname($system). Execute sub '$testname' with '$system' as parameter in object '$self'. Depends what do you mean by "... in object $self"? I see two possible interpretations of that: You simply want to execute the sub named in `$testname` (whilst incidentally running inside a method of object `$self`); in which case all you need is: `$testname->( $system );` [download] You'll probably need `no strict 'refs';` for that. Alternatively, you might mean that you want to invoke the method of object `$self`, who's name is held in `$testname`; in which case all you need is: `$self->$testname( $system );` [download] Seems to work fine with full strict.
