AAAAAAAAAAuuugggghhhhhhhhh!   Where the heck have I been?  Why isn't this
documented in the Query manual?  You should'a heard the head-banging when I
shared this response with the others in our office, which, several months ago,
undertook a _major_ project to convert user-written queries with hard-coded
selections to QM queries (both *QMQRY & *QMFORM objects).  It got so bad that I
ended up scrapping some of the conversions and wrote RPG/CL from scratch; much
faster to production.

Well, so, I guess, Thanks for the tip!  Next time..........

If I'm not the only one who didn't know about this (which I suppose _is_
possible), I think this would be an excellent tech tip in the trade rags.  Per,
go for it; it might net you $50!

BTW, this technique _does_ do a conversion to *QMQRY, it's just transparent.
This is important to know, because there are differences between WRKQRY output
and STRQMQRY *QMQRY output.  But it looks much cleaner than the conversions I
did in the past.  Oh, and character host variables have to be enclosed in triple
single quotes, i.e., SetVar((STATUS '''A'''))

Will sleep better tonight.......

IBM har written a nice little paper about the subject "Passing Parameters
to a query"

Click the link below
In the search field write :

Passing Parameters to a Query/400 Query

The basic idea of the solution is in the select statement to write in the
Select part:


// Yes the : has to be there

Save the query as normal i.e. a QRYDFN object.

Run the Query with STRQMQRY and ALWQRYDFN(*YES) and set the variables in

I.e. in the above case:

StrQmQry QmQRy(yourlib/yourqry) AlwQryDfn(*YES)
     QmForm(*QMQRY) SetVar((FROMDAT 19991122))
