First C Program

Hi James



Thank you for your reply. You have corrected an impresion I had.

hmmm I am tempted to use a macro to code !> as <>.

FWIW I got the guidelines directly from Paul Contes book.

Looks like you have discovered a typo in the book.



Yes you are correct I ported an RPG program to C as a training exercise,

but also I had in mind 2 other goals.

1. How to use the i5 data base using record I/O in C

2. Compare an RPG program with an equivalent C.

I believe the exercise has opened my mind to the world of C on the i5.

Without the 'function libraries' C is a very limited and difficult.

With the function libraries C becomes as practical as any other language.

Possibly the only place C would be used without function libraries is

on PLC controllers but even then I doubt that.

2. (and possibly NE instead of <>),

Uh, I don't think I've ever encountered a C compiler

for which "<>" had any meaning whatsoever.

In C, the "not equal" operator is "!=" rather than "<>"

(and that is also true of such C-derived languages as Java).

And what is the point of porting an RPG program into C,

unless it's simply a training exercise?
