Join fields from two files on a key - DFSORT TRICK 6

In this section, I will show some tricks for joining fields from two files in different ways using the JOIN KEYS function of DFSORT A customer asked the following question: I have two files with a key in bytes 1-3 and data in bytes 5-9. File A has the following records: 000 $$$$$ 001 AAAAA 002 CCCCC 003 EEEEE 004 GGGGG and File B has the following records: 001 BBBBB 003 DDDDD 004 FFFFF 005 HHHHH I want to join the data fields for pairs of records with the same key to get the following output: 001 AAAAA BBBBB 003 EEEEE DDDDD 004 GGGGG FFFFF Note that each file is already sorted by the key. Can I do that using DFSORT/ICETOOL? The answer is Yes, you will see the complete JCL in this Video.
