The COMMON session I used for a few years was 
"Coding External I/O modules using RPG".

It was primarily to demonstate how to move more towards OOP 
even using RPG.   (Abstraction, Encapsulation, etc.)
The routines were to write to the IFS in a .CSV comma delimited
format.   (I have mailed it out at least to 25 or more people on these
types of lists. talking about code sharing)    

I think the feedback I got was real good.   A large number of people
who attended(200-300) never saw procedures before and the 
prototypes for the API's  ...... well they struggled with them.

So I guess (and since I do education)  I tend to voice my 
opinions for the masses so to speak.   I do think the majority
of AS/400 IT people are more focused on the "Business"
aspect of programming,   as opposed to the  C/Unix's
people's focus on the "Way Cool" aspect of programming.

Well  Soap Box (*off)

Joe,   Take the examples,  read the great articles in 
mags like News/400,  Midrangecomputing, etc.  and 
play with it.     The example you have of mine runs
quick and you can encapsulate it (that was the 
point of my session) to hide the gory details and 
just call it from other programs.

The API's themselves are one learning curve,
the other is Codepages,  CCIDs,  End of line(etc) 
characters,  and the other surrounding things 
you must learn to make it work.   

Like the realllllll inteligent things in Unix like
Opening the file once(to create it with the right
authority, etc.) then close the file,  then
open it again this time telling it (with a real intuitive 
number BTW) to tell it  to translate from EBCIDIC
to ASCII.    

Because of these things above that I humbly thought 
that if we had a "Read/Write" type function
in RPG that did those stupid things that
aLLLLLLLLLLLLOOOOOOOTTTTTT
more programmers would be using the 
IFS in their programs sooner.   Those
C examples in QSYSINC  Really help
someone at work,  stealing time outside
of a project to learn something new. 

End of Quote.  End of soapbox I semi promise.

Look at these,

 D     O_CODEPAGE      S             10I 0 INZ(8388608)
 D     O_TEXTDATA      S             10I 0 INZ(16777216)

Does anyone know why the CODEPAGE is that number?
No, and you won't see aaaaaaannnnnyyyyyy 
documentation anywhere of what the valid numbers
are, or why they are those numbers??  Its a 
"Trust me they work,  don't miss key them"
