Re: Long Constant Names -- RPG400-L

Antoine,

Personally I'm not sure why you need context in the variable name.  Context
should be provided by where the constant is defined.  Don't define the
constant in a global list but define it in the procedure where it is used.
If that requires multiple definitions of the constant in multiple procedures
then accept that or put
the constant definition in a /copy book.  If it's in a /copy book then the
name of the copied member would also provide the context (/Copy AppState).
wwUpdateFailMsg won't work as a variable name if it's defined 'close' to
where it is used?

I'd also try to take Msg out of the constant name.  That's really a 'type'
suffix you've added on to the name.  Lowercase m might suffice as either a
prefix (polish) or a suffix.  wwmUpdateFailure won't work as a variable
name?

the reason I'm talking about constant names specifically, and not variable
names in general. Generally speaking, the constant should state both the
context (e.g.,
