Re: Module source naming schemes -- RPG400-L

Scott,

Yeah, I'm not happy with the 'F' 'N' and 'C' myself.  I am contemplating,
and probably will, go into the //copy member for this and create some constants.
RNF_Open 'F'
RNF_Next 'N'
RNF_Close 'C'

One thing I have found irritating when I code this is that I only need the
first two parameters when I first call this thing.  And every other time I
actually don't need any parameters at all if used from a first to last 
situation,
and I really don't even think I have to set on LR for this thing, since it's
in activation group *Caller anyway.  And if you wanted a new set and passed it
the 'F' again it would resetup the pointers.

So, all I really need to know is if it's the first time or not, and if it is the
first time, what the username and system name are.  Hmm.. perhaps 2 calls then.

RtvNetFIni(UserName, SysName)
RtvNetFNxt()

The question then becomes, how do I define my variables so that both RtvNetFIni 
and
RtvNetF can see them?  I am thinking if I declare them at the top of the source 
file
outside any functions they will be global to that source file, and any module 
contained
in it, right?  But not visible to other programs, such as the RPG program.

Is this correct?

In which case, since they are global, I would want to define them as
RNF_Data
RNF_Options
RNF_Lib
RNF_Idx

My naming scheme for global variables (ones seen outside one program or 
function)
is three letters designating the function they are from, and underscore and 
their name.

Jim Langston
