Using a look-ahead with pos can save having to do the sums.

knoppix@Microknoppix:~$ perl -E ' > $s1 = q{ACTGGACGTATGCA}; > $s2 = q{AGTG-ACGC-CGCA}; > $m = $s1 ^ $s2; > push @pos, pos( $m ) while $m =~ m{(?=([^\x00]))}g; > $m =~ tr{[\x01-\xfe]}{\xff}; > $c1 = $s1 & $m; > @p1 = $c1 =~ m{([^\x00])}g; > $c2 = $s2 & $m; > @p2 = $c2 =~ m{([^\x00])}g; > printf qq{%-2s%-2s%6d\n}, $p1[ $_ ], $p2[ $_ ], $pos[ $_ ] > for 0 .. $#pos;' C G 1 G - 4 T C 8 A - 9 T C 10 knoppix@Microknoppix:~$

I hope this is of interest.
