Impressive post except for the shortsighted statement:
"Note to people debating RPG vs COBOL: if you are in your 50's or 60's
that's OK - retirement is soon. If younger, RUN to learn another
language. I think it will be amazing how quickly they will both be a
footnote in history!"
I seem to remember this being said in 1990. It is as incorrect today as
it was then.
Wake up. COBOL and RPG will be here in 2100. I cannot be sure of the
same for C and Java.

OK so there were dozens of responses but no right answers :)
The reason why RPG is the preferred language on iseries (and not COBOL):
follow the money!
IBM was bringing thousands of organizations into the IBM 360 computer
age back in the 1960s & 1970s, only to see them move to the "B.U.N.C.H."
three years later - where they could run COBOL for less $.
(Burroughs, Univac, NCR, Control Data, or Honeywell)
IBM had a choice way back when.
Guide clients to purchase IBM hardware and develop in COBOL ... and then
the clients would be running a "commodity" platform where they could
more easily jump ship in a few years;
OR
Guide clients to RPG - where the client was then CAPTIVE since no other
machine had a serious RPG compiler.
It's the same marketing philosophy as Gillete razors, Apple OS, and
Lionel model trains. Give away the shaver and the client cant go
elsewhere - they HAVE to buy your razors/software/train-cars!
COBOL was governed by a standards organization and also the federal
government had their FIPS standards - so IBMs hands were tied regarding
COBOL. With RPG, IBM owned it all and they could do whatever they
wanted to keep RPG from becoming a commodity.
Simple as that.
RPG has HUGE advantages over COBOL on iseries. Mostly not due to the
language itself, but the fact that so many users have created so many
widgets that users share knowledge, experience, books, and even code.
But RPG on iseries does offer the following huge language benefits over
COBOL:
Functions: with RPG one can create their own functions. COBOL doesn't
offer this, which is 100 nails in its coffin.
READE: in RPG this is one line of code; in COBOL it can be dozens of
lines of messy code (load the keys, read the file until keys not =, then
check the last record read for matching keys)
Note to people debating RPG vs COBOL: if you are in your 50's or 60's
that's OK - retirement is soon. If younger, RUN to learn another
language. I think it will be amazing how quickly they will both be a
footnote in history!

Hi,
I would like to know why RPG is the principal language on the i. Has it
always been so since the days of the AS400 and beyond? Is it just an IBM
thing?
Thanks
