This is very confusing. You really need to stop and think clearly

about what it is you're trying to do, and explain it better. As it

is, from your description, I can only assume you wouldn't add up *ANY*

of the numbers in the third column of the file.

Using my PSI::ESP module, I guess that you have a file which defines a

set of records. Each set starts with a number of the form '2xx' in

the first column. The second column of that row contains the number

in the first column of the next entry in that set. When the number in

second column is of the form '2xx', then the set is over, and you

should record the start and end numbers of the set, and the total of

the numbers in the third column of each entry in the set, and start

over.

But that's only a guess. Please try to be clearer about what you're

asking for.
