I have three files.

Code:

File A.
-------
000001         AAAAA  - Header
000010policy1
000020policy1
000020policy1
000010policy2
000020policy2
000020policy2
000099         AAAAAAAA  - Trailer

File B.
-------
000001         BBBBBBB  - Header
000010policy3
000020policy3
000020policy3
000010policy4
000020policy4
000020policy4
000099         BBBBBBBB  - Trailer

File C.
-------
000001         CCCCCCC  - Header
000010policy5
000020policy5
000020policy5
000010policy6
000020policy6
000020policy6
000099         CCCCCCCC  - Trailer




My requirement is I need to merge all these files to a single file .
but the header of first file (file A) should be maintained as a header for the final file and the Trailer of the last file (File C) should be maintained as last trailer for final file.
and the records in the file should be merged in the same order as its in the file a,b,c.

the output should be like below.


Code:

000001         AAAAA  - Header
000010policy1
000020policy1
000020policy1
000010policy2
000020policy2
000020policy2
000010policy3
000020policy3
000020policy3
000010policy4
000020policy4
000020policy4
000010policy5
000020policy5
000020policy5
000010policy6
000020policy6
000020policy6
000099         CCCCCCCC  - Trailer

mainframemouli,

How do you identify the header and trailer in the files? What is the LRECL and RECFM of all the 3 files?

All the three files are of length 80 and they are Fixed block.
The header can be identified by the position 5 to 6.
(i.e) if the position of the (5,2) is '01' then its a header and if its
'99' then its a Trailer.
