hi. i've wrriten an ftp program that every hour with check a directory for files and if there are any it will upload them then move them to a different folder. i get the file list like this.....

tie %Dir, IO::Dir, "p:/charts/Sendtray/." or &WriteToListView2("Error opening directory: $!"); 

foreach (keys %Dir) {
     unless ($_ eq "." or $_ eq ".." or $_ eq "GONE" or $_ eq "") {
     push(@FileList,$_);
     }
 }

[download]

then upload then move.

the first time the files are uploaded everything works fine. when it uploads a second time i keep on getting bad file descriptor errors with a space instead of a file name. because i can't remove the files from @FileList because they're uploaded in a foreach loop, i undef them after they're uploaded and moved....

foreach $oFile(@FileList) {
         if ($oFTP->put("p:/charts/Sendtray/$oFile")) {
            if (move("p:/charts/Sendtray/$oFile","p:/charts/Sendtray/G
+ONE/$oFile")) {
            &LogSentFiles($oFile);
            $oFile = undef;
            }
       }
   }

[download]

so i figure the error is because of the undef working unlike how i expect it to. does anyone now how to stop this from happening?
