Re: Validate client name

David,

Why stick with an RPGII naming convention when programming in ILE RPGIV?

Personally, I'd consider a CLIENT module. Then in keeping with Adam's
suggestion, and prefixing the procedure with the module to prevent name
clashes...

CLIENT_CheckName.

Though I prefer procedures that return Boolean values to be named so they
read well in an if statement..

CLIENT_HasValidName()

Notice that not only do you remove the "noise" of a xxx999 module name, but
it becomes obvious what module your procedures should go into.
CheckCompanyName becomes COMPANY_CheckName (or COMPANY_HasValidName).

Now in six months when you say, hey I need to see is a client has a valid
name, it's easy to see that you'd want to look in the CLIENT module instead
of trying to figure out if you put the procedure into module CHR000, or
STR000 or TXT000. In fact, more likly when you're in doing something with
clients, you'd copy the CLIENT prototypes in automatically. Then if you're
using WDSCi or RDi, a refresh of the outline would show you the procedures
available.

To reiterate....

You're beginning a new paradigm of development. Don't tie yourself down
with old and unnecessary rules.

Thanks again to all who responded.

Now I might sound a bit picky here but here goes.

Checking that a field has only characters A-Z is not dependant on a client,
so I suddenly had the following brainwave :

Create a new module.

Copy Barbara's code into a function like CheckClientName or something. For
a company name I'll add CheckCompanyName and change the constant containing
the accepted characters.

Profit from the simplicity of this module to persuade the boss to let us
integrate it as our first service program.

I'm already realising, however, that the names of the functions and the
module aren't that easy to think up, bearing in mind that it could be used
universally.

So putting Client into the names of the functions might not be a good idea.
What about the module name? I have to respect a rule of 3 characters and 3
numbers. Should I call it CHR000 or STR000 or TXT000?

Thanks
