RE: i/o module

The idea is that a program doesn't have to know anything about the database in order to use it. This has become a topic since we were joined by team of JAVA developers. Since I had to create a new PF, I got the order to create a separate I/O module as a kind of guinea pig for future developement, the idea being that we would do the same for every new file on the system.

All fors and againsts are extremely welcome and I thank all those who have responded so far.

Just because I am curious, and have some scenario based opinions on the matter, why are you looking to externalize your DB IO from RPG? Or rather, what are your ROI points given the work required to write the code?

Hi,

Does anyone have some code that they could post for externalizing file
i/o operations ?

I've had my first go at this and although it works I'm not fully happy
with it.

To replace an RPG CHAIN operation, my program does something like IF
NOT ReadFile ( ), and the function ReadFile will do a CHAIN.

However in replacing a loop like

SETLL File

DOU %eof

READ File

ENDDO

I use another function that uses an SQL cursor. I realise that this
last function could also do the same as the ReadFile ( ) , but should
I replace a simple CHAIN by SQL?
