Looks like the K&R book is the way to go. No one has mentioned any other.
Have you still got your solution for exercise 5.20.
If so can I have the code please?

I am using the iSeries C compiler, so far so good.
I dont have a tutor, so my problems are my own.

I certainly intend to not use "C-style" but its a two edged sword
what to dont use you lose.

I know the problem of function upon function upon function etc. I
have seen this is RPG ILE and I am wary of it.

I am up to Ch 5 in K&R and I think I have a good understanding so far.
>From another old programmer I understand what you mean.
I am learning C because I got bored.


>Good luck!
Thanks
