Is it the final report that you are really after?  Then perhaps the GROUP BY, 
or HAVING clauses, are what you want.
If you want to
a) print a detail report
b) print a summary report by one control break
c) Print a tighter summary report by another control break.
Then you might be better off to use SQL, (OPNQRYF if you just have to), to 
select and sort data for step A and write out data at control break time to a 
temp file.
You could then process that temp file.  Whether or not you have to use SQL (or 
OPNQRYF) may depend if you have a different sort (sales by city sorted on 
sales).  Again writing out data to another temp file at control break time.
Then again process that last temp file.  Whether or not you have to use SQL (or 
OPNQRYF) may depend if you have a different sort (sales by region sorted on 
sales).
You might get some suggestions for CPYFRMQRYF but that may not be the best 
solution for this situation.  As this may imply 5 OPNQRYF's versus 3.  The 
CPYFRMQRYF would make RPG cycle programming easier.

Method CPYFRMQRYF
OPNQRYF/CPYFRMQRYF
RPGLE with no disk output
OPNQRYF/CPYFRMQRYF
RPGLE with no disk output
OPNQRYF
RPGLE with no disk output

Method 2)
OPNQRYF
RPGLE with disk output
OPNQRYF
RPGLE with disk output
OPNQRYF
RPGLE

Method 3)
One single SQLRPGLE program with 2 temp files.

Subject:        OPNQRYF questions...

1.  I want to use a series of OPNQRYFs where the results of the first is
used in the second and those results used in a third, is this even possible?

2.  If the OPNQRYF is joined with the record format specified, what file is
the opened one?  Is it the first one specified in the join, or the one
specified as the record format?

Examples would be helpful as the books aren't...  Thanks!
