in reply to Returning multiple values from a subroutine

Hi, You are returning an Array reference and scalar reference, but the value get assigned into an array, So both the returning reference saved into @subs array

.

change the code as

my ( $subs, $SubId ) = getsubsFromAcct( $currAcct ); my $length = @$subs; print ("No of subs : $length and subs are @$subs");

    Thanks for the quick reply :) it worked

      I'm glad it does. However, what I find more interesting is whether you understand why it works. References can be a tough subject to grasp. But you do, it's an immensely powerful tool that you should be glad to have in your toolbox. So are you just taking ree's solution as-is, happy it solves your problem, or do you see what he did and how that works?

[Discipulus]: while (readdir DIR) was wrong too; it is while ($_ = readdir DIR)
[Corion]: Discipulus: I have to admit that nowadays I either use Path::Class or use File::Find or simply File::Glob:: bsd_glob to read a directory, depending on how fancy my needs are
[shmem]: Discipulus: while (readdir DIR) works fine
