RE: Activation Groups and Threadsafe -- RPG400-L

Hi Eric, Thank you for your reply.

If I am picking terms 'out of the air' then your reply is
similarly miss directed.
Did I say anything about ' Ingore the buzzwords and
study up on service programs, subprocedures, procedure prototyping, and
%Bifs. These are (to me) the best parts of RPGIV.' 
What makes you think that I do not use these things.

What makes you think that  'If you truly believe that RPGIV makes
 programming MORE difficult', I said nothing of the kind.
And you fail to answer my question on Activation Groups,
perhaps if you have nothing good to say than you should
say nothing.

I have the basic idea of threads and you have not shed more
light on the topic than I already know.
Thanks anyhow.

Frank,

You seem to be picking terms out of the air, here. Activation groups have
nothing to do with threading. I believe activation groups bear as much
resemblance to MRTs as your as400 appears to resemble a pocket calculator.
Sure, you can pick out one or two aspects of ILE that seem to be similar to
older technology you've abandoned. But, how long since you were that boy
playing with MRTs? 15 years? more? Gee, could IBM have really taken a decent
(though hard to implement) idea and made it better? simpler? faster? easier?
(Sorry for the rant, I've had this argument too many times with a former
boss who was reluctant to look at RPGIV because it reminded him of something
he disliked from years ago.) 

If you truly believe that RPGIV makes programming MORE difficult, then you'd
better think about retirement asap, cause you've totally missed the boat.
IMO, more than 80% of the benefit of RPGIV is the improved readability and
maintainability of the code. Ignore (for the most part) the parts about
override scoping. 

Threads are spawned processes. Think of SBMJOB and you've got the idea of
threading, though it does get a bit more devious. Don't worry about it too
much, since RPG doesn't support threading (afaik). It's more in the realm of
Java and Webshpere that you deal with threads. Ingore the buzzwords and
study up on service programs, subprocedures, procedure prototyping, and
%Bifs. These are (to me) the best parts of RPGIV.
