Thanks Tom. It's not homework. I'm trying to parse html chess notation
from a site into FEN. I labeled the blank spaces 1, now I need to add
them up wherever they occur. Just for fun.
What I have tried failed miserably and I'm not sure why.
for ($n = 8; $n <=1; $n--) {
if ($temp =~ /(1){$n}/) {$board =~ s/(1){$n}/$n/;}
}
My Thoughts were:
$temp holds the string I am searching through. What I thought I would
get is:
if $temp matches 1 {8 times} then replace 1 {8 times} with 8. It would
count down. 8 1's would get an 8, 7 1's a 7 etc... Didn't work.
I'll check out what you suggested.
Cheers,
Eric

I have a string like:

I would like to replace the 1's with the total of 1's like this:
5xxx2xxxx6xx2x1xxxx
Hmmm.... Smells like homework. What have you tried so far?
Your missing pieces of the puzzle may be: the /e flag on an s///
substitution, the length() function.
Good luck with it!
