  • Your deref $self->_getGood() twice, but the dump shows it's just a reference to an array of strings.
  • Your map returns a list of file names, but you assign it to a scalar. That sets $files_to_send to 6, the number of file names.
    Your map would return a list of file names, but you assign the result to a scalar. This causes map to return 6, the number of file names.
sub _getGood { my ($self,@args) = @_; print "_getGood()", Dumper $self->{_good}; # Returns a list of of 'Cxxxx' codes. return @{$self->{_good}}; } my @files_to_send = map {"$stage/$_.pdf"} $self->_getGood(); print map {"$_\n"} @files_to_send;

Update: The word "twice" was missing.
Update: Adjusted the wording for clarity in response to merlyn's reply.
