Document "DB2 Universal Database for iSeries SQL Reference" has this to say
about SELECT INTO statement:

"This statement can only be embedded in an application program. It is an
executable
   statement that cannot be dynamically prepared. It must not be specified
in REXX. "

All valid points.  Yes the assumed target for the output was the display.
Hence the term 'poor mans STRSQL'.

However I don't think a simple
select datafld into :Myhostvar
 from myfield
where primarykey='xyz'
Can be prepared and executed without a cursor.  And I've had to set up
some cursors for this.  Which, when you think of it, 'should have' only
one return row.

I do not understand your point...
By definition, SELECT statement returns a set of records.
To work with a set of records in a procedural language, you need a cursor
(to iterate through the set of records returned).
So yes, SELECT requires a cursor.

In your example

SELECT_STMT2 =  'SELECT RRN(T), QRECN, QTITY, QTISTY ',
                'FROM QAYPETIDX T',
                'ORDER BY 3   ',
                'FOR FETCH ONLY '
EXECSQL,
     'PREPARE S1 FROM :SELECT_STMT2'
(* ) EXECSQL,
     'EXECUTE S1'  <-- this won't work, you need a cursor

When statement (*) is executed without cursor - what is the target of
select?
Where values for RRN(T), QRECN, QTITY, QTISTY are supposed to go.
When you work with STRSQL or QM, there is an implicit target - display
screen or printable report - with a lot of rules, how this should look
like.
When you use procedural language, it is your responsibility to provide a
target for select list. And the vehicle to relate select list to program
variables is cursor (and a FETCH statement).
