Re: Tracking down "uninitialized value" errs

You could use a WARN handler. Something like:

    $SIG {__WARN__} = sub {
        require "Carp.pm";
        Carp::cluck @_;
    }

This will give you a stack trace of from where the warning occurred.

Thank you so much! This led me right to the problem, if rather verbosely. It turns out that whilst streamlining my code, I made incorrect use of a hash slice that brought in more values--some of which were undef--than I had intended; these had no effect on the display but generated errors.	[reply]
