Re: C coding

Compared to C++, C is quite elegant, simple, and not overly complex as C++.
And if you're building a big system (not some one-off utility or tool), and
therefore have a need for OOP, choose Java or something else.

And C is also very platform independent, meaning you can compile your C
source without issues (if the code is a bit disciplined) on any known
platform known to man. Not so for C++.

Just a couple of quick comments - why C ? Other than folks writing
operating systems is anyone using it that much any more when there's C++?

As to training the C folks in RPG - we've done a lot of that lately and
most of them love it. Just ensure that you ONLY show them free-form and
that you keep them well away from SEU. Free-form and RDi only!

Thank you Marc and Buck

Much appreciate your feedback.
The key information I am hearing is to use C appropriately and
in a disciplined manner.
One can then leverage on the existing large C skill-set and
bring on expertise to the IBM i that would not usually be available,
at the same time I would introduce the C experts to the power
and simplicity of RPG and so have a win/win situation all round.

I think I have stumbled onto an interesting avenue to explore.

Thanks to all who have replied.

We do a lot of C++ coding and primarily benefit from its
cross-compilability between with windows and Linux (if you do it in a
disciplined fashion). It also allows us to leverage existing tools and
skill sets across the organization. We even use it for a fair bit of
database access as we've wrapped the SQL api's into a nice reusable
object. That said - most of the coding in our department is 'tools'

coding.

HTH,

Marc

So I am prompted to ask, is anyone doing serious coding in C on the

And if so what is the application and more interesting to me what style

C code is being used?

I have C code in production that I used for ASN.1 serialise/deserialise
operations. Also, for socket operations. Both of these are wrappered
so that ILE RPG programs can call the functions.

Today I'm not sure I'd recommend using C for sockets; there are plenty
of RPG examples these days (thanks Scott!) But there are some
programming chores which C works well for, AND for which one can find
examples on the web.

Generally speaking, I do all my IBM i database work in RPG. I'd use C
for tool / interface type work. At home I use C to program PIC
microprocessors; another chore that uses no database. ish.
