I have two files , where one file is having LRECL = 6 (FB) and another file having LRECL = 90 (FB), File 1 has only one record of length 6 bytes and File 2 can have many records ,
My query is , can I put the value in File 1 which is of length 6 bytes into the header record of File 2 at position 5 leaving rest of the record and fields as it is. Example is as below.
If your one-record file had something identifiable on, and was a 90-byte record, you could do it with a concatenation and IFTHEN=(WHEN=GROUP and RECORDS=2. Even with no identification, you could do it by generating a sequence number (use more resources that way, though). There's JOINKEYS (more resources).
Or a two-step approach where you generate a symbol/SYMANES for your one-record file, and use the generated symbols on SYMNAMES in the second step. There are examples here. For instance.
