Could you clarify the question.
Example: If I get the input line
___
I want this output line
___.

Subject: computations with backreferences
Hi all,
I have a regex, it's isolating some numbers in each
line of a text file and I want to add some computation
with those numbers on the same line. I know you can
basically stick any function in a regex but I don't
know how. Hence, the code below won't work:
$_=~s/^[A-Z]\t(\d{1,2})\t.*\t(\d{2})\t.*/$1\t$2\t($1+$2)/2/;
The forward slash that would terminate wrongly the
regex is actually a "divide by".
What is the correct way to do it?
Thanks,
Dan
