RE: *INZSR - I still love you!!!

Having said that, if I could walking in someone else's shoes for a moment
and suppose I was using another language (primarily) and not familiar with
RPG, then yes, *INZSR would present an interesting learning curve to me.

RPG isn't the only language that has initialize type functions that only
execute the first time they are called.  When I was programming Java
Servlets awhile ago I used a init method to create a pool of iSeries
connections.  I only wanted that to execute when the Java class was first
loaded by Tomcat and the init methods were my ticket.  I am sure there are
many other languages out there with the same thing.  Constructors (in any
language) would also be a comparable to *INZSR. . .

To put it short *INZSR adds functionality to RPG.  If you need it you can
use it, but make just make sure you understand how it works and you will be
set (like Cozzi said).

Maybe *INZSR is the poor mans constructor ;-)

Tony,
I'd have to both agree and disagree with this one.
I think the use of the *INZSR was very viable in RPGIII and is still viable
today with RPG IV. 
I've never bought into the notion that just because you can't see the code
in front of you, the feature shouldn't be used. This is the kind of excuse I
hear all the time when I ask people why they avoid /COPY like the plague. 
Having said that, if I could walking in someone else's shoes for a moment
and suppose I was using another language (primarily) and not familiar with
RPG, then yes, *INZSR would present an interesting learning curve to me. I
would probably spend hours (days?) trying to figure out what the heck was
going on.... But then I'd learn *INZSR and its function and I'd be set for
the rest of my career.

IMHO, if there are tasks that need to be done at the beginning of the task
at hand, I simply code them at the beginning of the C-specs.  Perhaps this
is because I don't rely on the eternal repeating of the entirety of the
C-specs.  

I could see the enhanced 'neatness' of moving these 'initialization' items
to a subroutine, but beyond that, *INZSR simply adds to the 'mystique' of
the program, by not having to EXSR that initialization subroutine.  At a
glance, it forces you to first look towards the bottom of the code, or
search for the *INZSR text to see the program flow.  

Just my opinion.  Take it or leave it.
