Re: Generic RPG File Handler for File I/O using OA

Thanks. Just wondering how does OA get name/value pairs of the fields from
a record, I always dreamed of looping through fields and their values in a
generic way without using field names.

Following article is very old but this gave me this crazy thought :)

That's not what RPG OA does... RPG OA lets you use traditional RPG
native I/O file operations, but instead of accessing the table, it calls
your code.

So you couldn't use it to create a procedure with parameters like you
suggest.

Instead, I would simply write a procedure like the one you describe.

update/insert/read only those fields in field names/values. Now I can

use

this procedure in my programs to do I/Os. RPG OA allows some kind of
handler program to do similar functions. But I can't find any good
example :)
