Re: What is the difference in RPGIII and RPG/400

[Scott Klement <klemscot@xxxxxxxxxxxx>]

Hi Susan,

As I understand it...

RPG/400 is an implementation of RPG III.  In other words, RPG III is a 
language, and RPG/400 is a compiler that compiles that language.

What your boss may be thinking of is that in RPG III on the Sys/38, the
compiler was also simply called "RPG III".  He may be comparing the
changes that IBM between the AS/400 compiler and the S/38-compatable 
compiler.

To make matters more confusing, the compiler for RPG IV is called "ILE
RPG/400" which is basically just saying "RPG/400 for the Integrated
Language Environment".  (Which is confusing, since people associate
RPG/400 with RPG III)

So...   hope that helps.
