Thanks,
but the problem actually lies deeper in my script, for example :
$test = "hello";
$s = "(hello)";
$r = "$1 world";
$test =~ s/$s/$r/;
print $test;
output : hello and not hello world as I would expect.
Is there any way I could do this ?

Similar problem, different context. In perl, double quotes
causes interpolation, so in
$r = "$1 world";
$1 is substituted with whatever was matched in a previous
regex. To prevent interpolation, use single quotes.
That doesn't solve the whole problem, however. Now we need
to substitute the strings, including metacharacters, into
s///. To interpolate, then substitute, I'll use an eval:
$s = '(hello)';
$r = '$1 world';
$_ = 'hello';
eval "s/$s/$r/";
print $_;
A good general rule to follow is to use single quotes
if you want the string as is, and use double quotes if
you want interpolation.

Thanks, it was the eval function that does the trick. Believe me, I have tried quotes, double quotes and everything that goes along with it many times before posting my question here but it never seemed to do what I wanted.
Thanks again !
Cheers,
Mario.
