Think of the R/A as a sort of list of pointers to the records, ordered 
by the sort.  The compiler does all the magic of fetching in the record 
that relates to the pointer, so all you the RPG programmer need to do is 
assume that the records are being read like a primary file, ordered by 
the sort.  You can basically ignore the R/A part of it.

What do you need to change?  This is almost certainly a report, so I 
can't imagine the change is too drastic to be done with the program in 
its current state.  If you really can't wrap your head around it, the 
next step is OPNQRYF to replace the sort, delete the E spec and change 
the F spec to IP.  If it's the cycle that's causing blurry vision then I 
guess a rewrite is in the cards.  Just think of the ADDROUT (address 
record output) file as a black box that lets you read the records in order.
