The following is from a single text file that contains several
batches.
Each batch is seperated by the Batch Delimiter.
Each batch can have multiple 6 records (first field), but only one of
all the other records (1,5,8,9).

My Problem:
The third field of the 6 record is totaled within each batch and that
amount is inserted into position 4 of the 8 record and position 5 of
the 9 record.
On some batches this amount has been calculated incorrectly. How can
I fix this programatically? The number of batches varies within each
file and the number of 6 records varies within each batch.

While the first batch is correct, the second batch has two 6 records
and this amount is incorrect on the 8 and 9 records.
