I am trying to find any text in a file with the following characters in it:
r+c.mod
and doing a substitution as follows:
s'r+c.mod'D:/spice/r+c.mod';
but, for some reason (tell me what I am doing wrong please) PERL cannot
find the instances of r+c
Anyone have any ideas on how to get this to work?
Thanks!

See `perldoc -f quotemeta`.
s{(\Qr+c.mod\E)}{D:/spice/$1};
s{(?:=\Qr+c.mod\E)}{D:/spice/};

You need to escape the + and the . characters with a \ . So it should
look like below (not tested though)
s'r\+c\.mod'D:/spice/r+c.mod';

You'd better skip that colon.
But personally I would choose pinaki's solution with two plain backslashes.

But it could find instances of rrrrrrc.
A plus sign in a regex means "one or more of the previous thing".
You need to backslash it if you want to match a literal plus sign.

s#\Qr+c.mod#D:/spice/r+c.mod#;

Yes, thanks for the correction.

And I wouldn't. Often these things head for using a variable.
Many s/$search/replace/ constructs should have been written
as s/\Q$search/replace/.
(The clearest exception is when $search is built with qr{}.)

You must escape + and . characters. Maybe you can use this
s#(r\+c\.mod)#D:/spice/$1#;
Note: I rather use # as alternative parentheses. The apostrophe is bad
readable for my eyes ;-)
