Minoru Massaki,
Norbert had an excellent idea to overcome the issue of having spaces at
the beginning or at the end. Converting to hex would overcome the issue of
truncation with JFY.
However you do NOT require 2 passes of data to insert the trailing
character using VLTRAIL and then use Joinkeys.
I have optimized the Job. The trick here is to use the same input file for
Joinkeys. The subtask2 file is where we convert to hex and perform the
JUSTIFY to RIGHT and pick of the last 16 bytes and then unhex that 16
bytes back to 8 bytes.
we are appending a 4 byte sequence number to match the 2 files. And since
they are already in order, we also have SORTED and NOSEQCK so that we use
a copy operation for Joinkeys.
Please note that this approach of converting to HEX can be used only
1. If your input file is F, the max LRECL you can process is 32760/2 =
16380 and you are using 4 bytes for the key there by reducing the LRECL to
32756. So you can only process a file whose LRECL is 32756/2 <= 16378
2. If your input file is V, the max LRECL you can process is 32756/2 =
163780 and you are using 4 bytes for the key there by reducing the LRECL
to 32752. So you can only process a file whose LRECL is 32752/2 <= 16376
