Hi ,

I have a requirement to combine records of two input files and write into one single file.In addition to this i need to update the trailer count.

The two input files AAA and BBB are of record length 799 and FB.
The output file is also of same format and length

AAA file will have 1-n records .It has only detail records indicated by record code (REC-CD) = 10 in first two positions

BBB file can have details records but will always have header record and trailer record indicated by record code(REC-CD) = 0 and 9 respectively in first position.


Example:

Lets say if i have 5 records in input file AAA .

AAA file :

10ACCOUNTNUM:123451
10ACCOUNTNUM:123452
10ACCOUNTNUM:123453
10ACCOUNTNUM:123454
10ACCOUNTNUM:123455

And lets say if i have 2 records in input file BBB with just one header and trailer record

BBB File:

020152602SYSCD
912000000

There is a count field in trailer record which occupies position 2-9 with length 8 .
I need to append the records of both files and also I need to add the number 12000000 in BBB file with the number of records present in AAA file
and update trailer count in output.
The data records and header record are copied as it is but the trailer record count needs to be updated.

So the output file CCC should have the following data

10ACCOUNTNUM:123451
10ACCOUNTNUM:123452
10ACCOUNTNUM:123453
10ACCOUNTNUM:123454
10ACCOUNTNUM:123455
020152602SYSCD
912000005

Could you please guide me on how to achieve this using SYNCSORT/ICETOOL ?

Concatenate the two DSNs to the SORTIN DD in a COPY operation.
