Constants in RPG

Hi people,

I'd like some comments concerning the use of constants. I've been asked to prepare a presentation to the team for a discussion on good coding practices, as the boss is getting tired of seeing this sort of thing :

* Global figurative constants
* Type relation = aunt
D gA C 'A'

myRelation = gA;

Now, I'd have written :

D gAUNT C 'A'

D gUNCLE C 'U'

myRelation = gAUNT;



Some questions :

I would normally not use a commentaire at the declaration of a constant. What do you think?

We use a prefix g to indicate a globally defined constant, and w for a locally defined one. When would you locally define a constant in a sub procedure? I think it's nice to be able to see the definitions close to the calculation specs, but isn't a constant almost always global?

What is meant by figurative constant? I thought it was one with a fixed value like *BLANK.

Thanks
