Hi,

I have a file with Header, Detail and Trailer records. The file is having a length of 200 and is fixed block

The records looks as below:
A20070810
B12343567
B23456789
B34567890
B12343567
C2007081000004

The record starting with 'A' represents Header, B represents the detail records and C represents the Trailer.

The C record is having the number of count of detail records.

Using sort we need to remove the duplicates in detail records. After the duplicates are removed, the C records should be updated with the new count of detail records.

Please suggest, if this can be achieved using sort
