in reply to open to a scalar variable

I'm not very familiar with this technique, but try this instead:

open(MESSAGE, "+>>", \$message) or die "no message $!"; open(WHOM, ">>&=", MESSAGE) or die "no whom $!"; open (WHAT, ">>&=", MESSAGE) or die "no what $!";
If $message is already a reference, try dropping the backslash too.

It's all fine and dandy until someone has to look at the code.

    $message is declared but not defined until the reference assignment is made.

    Anyway, unquoting $message and putting the &= into the mode argument worked. Thank you.
