Right, you can't have the same subfield in two unqualified different 
data structures.  There's no problem if you just have the same field in 
two different files; in that case, RPG happily moves the data to/from 
either file into that one program field.

If Booth's suggestion doesn't help, and you need to have two data 
structures, and if the database one could be qualified, I think it would 
work to use a single EVAL-CORR operation to automatically move all the 
same-name subfields between the two data structures.  (You need V5R4 for 
this.)

The idea of trying to do this with /copy files gives me the shivers, 
though.  It seems to me (probably naively) that it would be better in 
the long run just to do the required coding in each program.
