RPG is a language. Depending on who you ask it's either the best
language ever invented, or the worst. It's designed for producing
reports, but is often used for all sorts of "general purpose"
programming. Strong in file I/O, decimal arithmetic, and some sorts
of character manipulation. Weak in most of the things C is strong in.
ILE is an execution environment. Programs written in the ILE
versions of different languages can easily communicate with each
other. Programs written in the non-ILE versions can easily
communicate with other non-ILE programs, not so easily with ILE.
ILE is faster in call/return but has more initialization overhead
than non-ILE. Execution in general is faster -- better optimization
of code.
iSeries C/C++ and the newer versions of iSeries RPG and iSeries
COBOL are ILE.
With regard to RPG in particular, the differences between the
non-ILE and ILE versions are substantial -- essentially different
languages.
iSeries is the current name for the line of computers originally
known as S/38 and then AS/400. OS/400 is the operating system for
iSeries and AS/400 boxes. It is unlike any other operating system in
existence.
There are a few iSeries boxes on the internet that you can get time
on for free or a small charge, just to get your feet wet.
Post by SamI'm interested in a job that uses RPG programming with ILE. Are RPG
and ILE languages? I'm interested in the type of software the company
specializes in.
I've used C++ (unix), VB, Informix 4gl (unix), and VB.Net
Is this something that would be easy to learn? Are there some
websites w/ sample code/free intro's to it/them.
Also what exactly is AS/400? An Op System?
Thanks...
