Ah, that's what I'd thought to do, however I think I've missed a step. I
want to hide the subroutine referencing code from the user thus I want to do
something like this:-
my $Papp=new
iBus::Papp('debug'=>1,'callback'="::MySub",'LogFile'=>'/var/log/MyPappLog.lo
g');
$Papp->Start;
sub MySub
{
print "Hello world"; #:-)
}
So what I want to be able to do is to take the '::MySub' string and make a
reference to that subroutine and then execute that reference.
