What is a lexical file handle? I'm working my way through Ford's "Perl
Programming for the Absolute Beginner" (2007) and Lee's "Beginning Perl"
(2004), and they both use the FH style of file handle. Should I do
differently?
Thanks.

what's happening.

You can use substr() to get the string starting at 16 and going to

I think that Rob was onto something, here
is my 2 cents.
The print line should be like this:
print <
and not
print< < EOF
like you have. I think maybe that what is
happening is that the error that is being printed is saying that it cannot find
“EOF” before end of file

Thanks very much. It runs a LOT faster now.
Like 20 times or maybe even a bit more.
I'm now trying to verify that the result is still the same,
but I believe so.
So, thanks very much :)

Interesting,
I see from your regexp you use a \A and \z, from Perldoc this means:
\A Match only at beginning of string
\z Match only at end of string
I am not sure I understand this requirement?
^ and $ depend on flags, and
33 matches
