OPNQRY reference book

Yes, I'm sure both of the major aS/400 trade rags have had comprehensive
articles on OPNQRYF, which, IMO, is one of OS/400's jewels.  An extremely
flexible and powerful command.  Check out AS400Network.com and
MidrangeComputing.com and search their article indexes for OPNQRYF.

Here's my take on the single quotes / double quotes issue you raised.  I
*ALWAYS* use double quotes to surround character data.  Which is easier to
read - #1 or #2?:

#1: QRYSLT(' OHSTS *EQ %VALUES( '''A''' '''I''' '''C''' ) ')
#2: QRYSLT(' OHSTS *EQ %VALUES( "A" "I" "C" ) ')

Another thing, if I'm dealing with CL varibles in the QRYSLT, I always use
QRYSLT( &QRYSLT ) and build the QRYSLT string in the variable beforehand.
Since its been at least 10 years I've been using this method, I forget exactly
the problem that it solves, but I seem to recall that numeric CL variables are
a real PITA to deal with in QRYSLT.
