Move field from Header to Detail records in each group

I have input file with records in below structure -
HDR <ACCT. NO.1>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TRL <count>
HDR <ACCT. NO.2>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TRL <count>
HDR <ACCT. NO.3>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TTT <TXN Details>
TRL <count>

I want above records to be transformed into

TTT <ACCT.No.1> <TXN Details>
TTT <ACCT.No.1> <TXN Details>
TTT <ACCT.No.1> <TXN Details>
TTT <ACCT.No.2> <TXN Details>
TTT <ACCT.No.2> <TXN Details>
TTT <ACCT.No.2> <TXN Details>
TTT <ACCT.No.2> <TXN Details>
..
..
TTT <ACCT.No.3> <TXN Details>
TTT <ACCT.No.3> <TXN Details>

Can anyone suggest me the way to go forward with sample code?

Use OMIT to get rid of TRL

Use IFTHEN=(WHEN=GROUP to identify the HDR and PUSH the values from the HDR to each detail record.

Use OUTFIL OMIT to get rid of the by now redundant header, and BUILD to create your desired output.

By your reply, I can understand that my case can achievable.
But I want to know what each of those keywords does?
If any sample code is there, then this would be great.

Thank you very much.

This is what Bill has suggested. Bill..Please correct me if I'm wrong.

Try the below code. You can modify it as per your exact data length and offsets.

I would add the OMIT COND= for the "TRL" and the OUTFIL OMIT= for the "HDR".

If there is data you don't want, it is always good to OMIT COND= (or INCLUDE the data that you do want) so that fewer records are processed - plus, it is clearer what is being processed.

With OMIT= for the header on the OUTFIL, it is then easier to understand the whole process:

We don't want trailers, at all, they are nothing to us. First line of code.
We process informaiton from the headers onto thte data.
Now we don't want the headers.

thisak.

Note that you should read the 81:as "a temporary data position at the end of my record". If your records area variable, then it needs to be at the start of the record.

Thanks Bill.

Thisak,
First try to understand what this code is doing and then modify it as per your requirements.

Thank you very much - Bill & Mistah

Mistah, Thanks again for explaining that with code.
I'll try this and surely reply with the outcome.

Thanks,
Thisak
