my understanding is that true ILE should make the code shorter, is he using
true ILE?

Subject: RPG IV Performance




Hi all!  I've just heard some rather negative performance things on RPG IV,
and
wonder if anyone can give me some feedback on how true this might be.

We're working with a consulting company who is doing some performance
analysis
on some of our programs.  They seem very knowledgeable, and I have a lot of
confidence in what they've done up until now.  However, today they were
showing
us a mock-up of a trigger program they want to use.  As they explained it,
this
trigger program will be constantly running in the background for every user
on
the system to monitor changes to two files, and will feed data to a dataque.
The program they showed me was written in RPGIII, and I made my usual
request to
an outside contractor that this be done in RPGIV.  His response was "Sure,
if
you want the program size to be 5 - 10 times the size of an RPGIII program."
When I asked him to explain that, he only said that, in his experience, this
is
always true, and that it would have a very negative performance.  I even
mentioned removing observability (not that I really understand what that
means,
but I just read something the other day about that being a way to reduce
program
size!), and he said that might move it down to 3 - 5 times the size of an
equivalent RPGIII program.  The program will only be about 50 - 100 lines of
code.

Can someone explain if this is true, and, if so, why?  And, if true, what
does
this really mean from a performance standpoint?
