Two things:
First, it's better if you post to the list by NOT replying to someone else's
post. When you do this, it references the previous post via the message-id,
and appears threaded below a post with a completely different Subject line.
If you are starting a completely new thread, don't reply .. just create a
new e-mail to the list address.
(the problem with the above is that if I "mark the thread as 'read'", your
post gets ignored, and I never see it since it's buried below the other
thread's subject.)
On to your question.
s{\Q$var1\E}{$var2} is usually what you want, except that may very well
'quote' out the $ in $var.
I suspect what you really want is
$var1 = qr{roger? what the @*$!};
( perldoc -f qr ) (perldoc perlre) and (perldoc perlop) for more details.
I'd also recommend you add
use warnings;
use strict;
to the top of every script you write. This will catch a LOT of potential
mess-ups that would be hard to find otherwise.
