Re^4: Undefined value as a symbol reference

It looks like this is a version issue. I tracked down the 5.8.0 documentation, and according to that version of perlopentut, it looks like three-argument open and indirect file handles were not yet implemented.

No, the code posted only requires perl 5.6.0

If OP is getting an error he is not using perl 5.8.0

Looks like old perldeltas confirm your assertion: http://search.cpan.org/dist/perl-5.6.0/pod/perldelta.pod#File_and_directory_handles_can_be_autovivified http://search.cpan.org/dist/perl-5.6.0/pod/perldelta.pod#open%28%29_with_more_than_two_arguments Symbol was already CORE in the earliest version I could easily track down the docs for (5.003_7). Raises the question of where the OP got his version string; perhaps he'll be kind enough to post the output of `perl -e 'print "$]\n"'`. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l]

The perl -v that I posted in the original post was directly from the server I am using, I didn't make that mistake. That is why I was so confused as to why I was having trouble. I had the "camel book" right in front of me that said 5.6+ but it still wasn't working. All I can assume is when it was updated to 5.8 it didn't update correctly.	[reply]
