Rob,

You can get by without the SQL toolkit, but it is worth having either way.  The 
real 
power comes into play when you realize that the fields and the return location 
are 
variables. Extending this out, you can then get down to a single procedure that 
handles all lookups. Once all of this code is centralized and shared by all of 
your 
programs it is easy to justify built in support for things like dynamic 
scanning, 
positioning, ordering, etc. The SQL is only one layer but it is an important 
and 
powerful one. 

That means that you can easily build your requests on the fly.  I agree that 
it is not hard to code a declare cursor, but when I look at code for SQL 
procedures 
that I have written I find a lot more.  In my code I find prepare, fetch, open, 
close, 
recover and error handling, etc.

Is this one of those techniques to use imbedded SQL without purchasing the
SQL toolkit?
Do you use CRTBNDRPG/CRTRPGMOD to compile this versus CRTSQLRPGI?  If so
what other binding directories, if any, are needed?

Frankly I find the 'Eval SQLHandle...' stuff more complicated that doing
the standard C/EXEC SQL technique.  How did you figure this stuff out -
looking at output from the SQL precompiler?

I take it that SQLOpen will take the fields returned from 'Select * from
...' and store it into the data structure whose address is based at
%ADDR(InputArea) when SQLFetch is executed?

If I study this for awhile, it makes sense, but then having a firm basis in
how the C/EXEC SQL stuff works helps, especially declaring, opening and
fetching from a cursor.
