It is always discouraging when the very first
'Hello World' program in a book fails on a
syntax error (needs quotes). I have now tried
the program on three different Linux installations
of Perl/Tk (800.014), but they all fail on
this first program with a 'undefined subroutine'
message. I bought the book only last night,
without realizing that the January version
is obsolete given the huge errata.
I am disappointed in this book so far, this is
not up to what I have come to expect from O'Reilly.
[I have bought over 40 of their books and found
them superb with one or two exceptions only.]
If this were software, I would demand an upgrade.
Can one trade in these obsolete versions?
-or am I stuck with this $32.95+tx turkey?

If you want to buy this book, make sure you
get a recent revision.
