The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Short answer---Yes!
Long answer---I really like what someone else outlined briefly - use Query Management queries and forms. They are similar in concept to good old Query/400 queries - those put both the data retrieval (QM query) and presentation (QM form) into one object.
You can even import Query/400 query definitions into QM objects, which are compiled objects.
A QM query (*QMQRY object type) simply holds and SQL statement, SELECT for reports. It can have substitution variables, meaning you can call it from CL with input values.
A QM form (*QMFORM object type) holds the layout and is best created and maintained using STRQM - same for the *QMQRY.
Once you have the query and form worked out, all you need is a command with the parameters you want to use, a command-processing program that takes those parameters, and then that program uses the STRQMQRY command with the form specified and with SETVAR parameter set to the input values. Voila!!
There is a Query Manager - that is STRQM - and that has options for doing both queries and forms. It has an appearance similar to Query/400 if you want at first - then you can get an idea of how the SQL is going to look. And the forms part is very like Query/400 - with some nifty features, like 9-line column heading possible, wrapping text within columns, like that.
For ad hoc or quick reports I know nothing much better - very easy to do.
There is a Query Manager user guide that walks you through it nicely. It is at

And there is a programmer's guide that has helpful stuff - especially about converting from QRYDFN to QMQRY - at

There appears to be much SQL talent on this list, and I'm thinking I may be
way behind the times. So here's a "how are you guys doing it" question.
A typical example: A request comes in for a new report. It will require
the user to enter some selection data (let's say from and to dates), then
process a bunch of records within RPG. I'm still using open query files,
record select logic in RPG, etc. Are some of you using SQL to do this, is
it a better way, or just different? Would anyone like to share example code
of a clean lean application using SQL?
Thanks, Tim
