hakkr,

The first example works because the lexical @files is visible to the FileName subroutine (since both are defined within the Get_Saves subroutine block). This works because you have the scope correct.

The second example will not work for several reasons: 1, File::Find::find does not return anything; 2, \&FileName(\@files) is not a reference to a subroutine (only \&FileName is); and three, the @files in Get_Saves is a different beastie than the @files in FileName (the first is a lexical and the second is a global.

To use File::Find with the two seperate functions, you would need to use either global @files or a lexical @files defined outside of Get_Saves and FileName:

#!/usr/bin/perl

use strict;
use File::Find;
my @files; # could leave this out and just let FileName
           # auto-vificate global @files

Get_Saves();

sub Get_Saves {
   find( \&FileName, "/usr/local/apache/htdocs/service/" );
}

sub FileName {
   unless( ($_ eq ".") or ($_ eq "temp.svd"))
      push( @files, $_ );
   # This @files is either the lexical declared above
   # or an auto-vifified global if nothing was declared 
   # above.
}

update I really like goldclaw's Re: Sub in a Sub & Recursion but you would need to remove the "@files=" from the find since File::Find::find always returns nothing. Just do this:

#where to add stuff.
find(FileName(\@files),"/usr/local/apache/htdocs/service/");
return  \@files, $#files+1;
