These 2 web site are go reference, but what I am looking for is like the
example at the bottom of this memo, which tell you in RPG how the code it,
is there anything like that around using C within RPG.

Let me scream, holler, rant and rave yet again....
You guys may think it is progress to be sticking all this stuff into RPG,
and probably it is. But a few years from now when RPG is cluttered up with
all sorts of specialized little tricks, where will the programmers to
maintain it be found? What qualified C programmer is going to be doing RPG
maintenance work?
Jon thinks 10000.01 is a pain in the butt... wait til this stuff starts
hitting the update fan.
Sorry. I'll be quiet now. No need to call the authorities.

(Sigh)
Not more than a week ago, we had a very similar discussion
either here or on RPG400-L.
For a discussion on translating C prototypes to RPG, read
<http://www.springfieldtn.net/users/leslier/callc.html>
To see a list of function in the C runtime library, go to
<http://publib.boulder.ibm.com:80/cgi-bin/bookmgr/BOOKS/QBJAQY01/1.10>
Here's an example in RPG IV of calling rand and srand:
---------------------------------------------------------------
H dftactgrp(*no) bnddir('QC2LE')
D rand pr 10i 0 extproc('rand')
D srand pr extproc('srand')
D 10i 0 value
D num s 10i 0
D i s 10i 0
C callp srand(123)
C for i = 1 to 10
C eval num = rand
C num dsply
C endfor
C eval *inlr = *on
----------------------------------------------------------------
This program displays 10 pseudo-random numbers.
