Re: Open Access for RPG

Thou dost protest too much! As Jon said, you are not the target, the 
audience for Open Access - you would develop a handler - not really the 
same kind of handler that you described as having already been written 
and so easy to do.

One point of all this is to let regular RPG programmers have access to 
non-traditional IO targets - not a DISK or DISPLAY or PRINTER. And let 
them use nothing that they don't already know. This lets them do their 
work as they already have - yes, maybe they should learn new things. Or 
maybe it's not really necessary in their shop.

We write software to sell - we use APIs all the time - this is a thin 
layer over some APIs, and we already do HTTP stuff using the CGI APIs. A 
question asked here is, why is this needed? Will it get a lot of 
interest? Again, we are not the target, we could be a handler developer.

IBM are betting that there will be a sizable group of developers that 
need to get their work done quickly and efficiently. If a tool could be 
provided that doesn't require learning a whole set of API function calls 
or procedure calls (such as one of our products provide), they will be 
up and running almost instantly. That's a good thing, methinks.

I can only assume you have not read the OA handler documentation, else 
you probably would not have put up the example you did of a handler - 
there is a slight functional similarity, but in implementation, not 
anything close. And we are not talking only about generic file handlers 
here.

Vern
