Stepping through a file

Hi there,

I have a file containg this:

aabbccddeeffgg

And i want the following output:

aa
ab
bb
bc
cc
cd
dd
de
..
..

I have tried with the following:

..
while (($n = read(F_IN, $data, 2, $offset)) != 0) {
print "$data
";
$offset += 1;
}
..

But the output looks all wrong:

aa
abb
abcc
abcdd
abcdee
abcdeff
abcdefgh
abcdefghi
abcdefghij
abcdefghijk
abcdefghijk

Can anyone come with some insight? I'd really appreciate it.

Thanks in advance!

saridski.
