in reply to concat '\' with word
- De rigeur snarky answer to the question you've asked: yes.
- Somewhat more helpful answer to the question you should have asked: perlintro, and while we're at it, How to RTFM.
- Hand-fed answer:
# update Of course that should be '\' ... $foo = '/' . $bar;
If not P, what? Q maybe?
