Use a lexical filehandle and pass it back, it behaves just as a scalar.

$ cat > rubbish
sdfhi
rtrthr
dgdf
$ perl -Mstrict -Mwarnings -e '
> my $file = q{rubbish};
> my $fh = openFunc( $file );
> print while <$fh>;
> 
> sub openFunc
> {
>     my $fileToOpen = shift;
>     open my $fileHandle, q{<}, $fileToOpen
>        or die qq{open: $fileToOpen: $!\n};
>     return $fileHandle;
> }'

I hope this was what you meant from your rather terse question and that I have answered your question.

Although the question was terse, I think that is what the OP most probably meant. And yes, using a lexical filehandle enables you to use it almost as any scalar variable: to pass it to a function, to return it from a function, to take a reference to it, to store it in an array of filehandles or in a hash, to make it a local persistent object in a closure, etc., even if you don't know or don't want to know anything on typeglobs.

Ok. This is what I need. Thanks for answers.

Hi solomon243,
Welcome to the Monastery.
Your questions are more likely to gets a more accurate answers if they are more elaborate.
Since, you are just starting out here I think it would be good you check How do I post a question effectively?.
That been said, I think there is a trends here that might be of help Difference between File Handles and File Descriptors in function parameters..

Now I will conform to the rules

Could you give a little more of the "bigger picture"? ...some context will lead to more useful answers. We need to know more about what you're trying to do.
