What is reformat fields in Joinkeys?
A REFORMAT statement can always be used for a JOINKEYS application, and is required unless a JOIN statement with the ONLY operand is specified. The REFORMAT statement indicates the fields from the F1 file and/or the F2 file you want to include in the joined records, and the order in which you want the fields to appear.
How do you use join keys?

- FILE=F1 or F1=ddname must be used to indicate that the JOINKEYS statement applies to the F1 input file. FILE=F1 associates the F1 file with a ddname of SORTJNF1.
- FILE=F2 or F2=ddname must be used to indicate that the JOINKEYS statement applies to the F2 input file.
What is the use of Icetool in JCL?

What happens to the joined Records in joinkeys?
If you don’t specify a JOIN statement for a JOINKEYS application, only paired records from F1 and F2 are kept and processed by the main task as the joined records. This is known as an inner join. The joined records will be the original unpaired F1 records. If the F1 records are fixed-length, the joined records will be fixed-length.

How to sort unmatched records in joinkeys JCL?
FNAMES gives you the DDname to put in the JCL. For CHANGE, the INCLUDE is for the first record (known to match due to the test for ‘B’) not being equal to the second. It is not exactly clear what output you want here. Currently those are output as F2 appended to F1, and entire (twice the size) record written.
